RuralZED zero carbon homes

2010-01-05T21:38:00.018Z

I have mentioned zero carbon homes a couple of times on this blog.

The first one I mentioned way back in July 06 was the Earthips made from recycled materials. See article. The problem with Earthships is that they are lot of work to build.

This problem is solved by the land arks and garden arks that I wrote about in in July 09. See article. The arks are ready made and can simply be placed anywhere. The problem is that are very small and will never be a realistic replacement for the average family home.

Luckily ZEDFactory, the company behind the land ark has a solution, the RuralZED. An upgradable 3 bedroom house that is a pleasant realistic family home. It ranges from from level 3 to level 6 on the code for sustainable homes. Level 6 is the maximum level and is assigned to true zero carbon homes. The RuralZED can even surpass level 6 becoming carbon negative by using a vertical axis wind turbine to produce an excess of electricity that can be sold back to the grid.

The name RuralZed comes from rural in reference to the fact that 70% of UK homes are in rural low density setting of less than 50 houses per hectare and ZED (Zero Energy Demand).

The feature and technologies in the full level 6 house are very impressive: -

Southern side of the roof covered with 21 180 Watt PV panels

2 Water heating solar thermal panels

Vertical axis wind turbine

Northern side of the roof is green using sedum

Northern side of the roof used for rain water harvesting for non potable water

Wind catchers to continually supply fresh air in all rooms

Air sent to rooms warmed by heat exchangers that reclaim heat from outbound air.

Internal materials include stone and high density wood for thermal mass

All light fittings use LED's

All taps use aerating low flow fittings

Entire house uses 300mm of rockwool insulation

AAA high efficiency appliances such as an induction hob

Entire southern house is a pleasant glazed sun space allowing solar heat capture

Passive heating of space and water can be augmented by wood pellet burner

The house is REALLY nice

Ecotricity vs EDF

2009-07-23T09:49:00.003+01:00

EDF are running a 'green britain' campaign at the moment to support a national renewables awareness day. Leaving aside the debate as to whether their mix of coal and nuclear can be considered green, what's really cheeky is that they nicked Ecotricity's logo for it:

Npower and british gas are having a dig as well, claiming they are green every day of the year. Let the greenwashing begin !

LandArks zero carbon off grid homes

2009-07-19T10:20:00.012+01:00

Off grid zero carbon homes are about the most environmentally sound lifestyle choice you can make. Producing their own electricity and collecting and filtering their own water they have virtually no impact environment whatsoever.

The last time I wrote about zero carbon homes that could be completely detached from the grid (water, electricity, drains) it was Earthships. These homes are made of recycled materials (tyres, aluminium cans, etc) and adobe. They user solar energy (photo-voltaic and thermal), thermal mass and reed bed water filtration. and are very cool.

However Earthships are a quite large investment in time and effort to build. If you are looking for a simpler zero carbon off grid home solution then LandArks or GardenArks could be the perfect choice. These homes are easy to construct kits that can be built by the buyer or the company and have the following design features: -

They are made of wood sourced from FSC managed forests with cavity insulation made from sheep's wool.
They have a curved living green roof that has a greater surface area than the land taken up by the Ark itself and can be planted with species that match the local grasses, heathers, etc. This roof makes the Ark far more pleasant to look at allowing it to blend in with the landscape, produces oxygen, insulates the Ark and acts as a rainwater collection and filtration system.
Power is generated by a rotatable solar array and a wind turbine.
The Ark can be connected to the grid to allow it to use grid electricity when it is not producing enough and to sell electricity back when it is producing too much.
The Ark is raised off of the ground which provides thermal insulation and also minimises the damage done to the land when the ark is built or removed.
The Ark contains a log burner for heating and cooking.
People wanting a larger home could have multiple arks joined together.

The Ark comes in two sizes, The GardenArk is perfect for a place in a large garden, a home office, spare bedroom, etc. Here are some pics including two I took at the Hampton Court flower show.

The LandArk is a larger building that can be used as a holiday home or primary home. Ideal for a group of friend wanting to buy some land and creating a small eco community. Here are some pics.

The Company site can be found here, good information can be found here and here is a page from the Grand Designs show website.

2009-01-12T16:40:00.003Z

An expedition is being mounted this year to drive from London to Tombouctou. The big difference is the expedition will use a Biofuel powered flying car. The car is a 2 seater buggy with a huge fan on the back that can fly by deploying a large paragliding wing. They are also hoping to make a production model by 2010. This will offer the performance of a sports car and a light aircraft and I WANT ONE.

You can also calculate your own index here:

Silliest idea ever

2008-05-06T21:47:00.002+01:00

This one actually works though. UPS now plan their routes in the US so that they make right turns in preference to left turns. This means they spend less time waiting to cross the flow of oncoming traffic and therefore use less fuel. Over the entire fleet this seemingly daft idea has saved them 30 millions miles and 3 million gallons of fuel. Scarily that implies their vans only do 10 miles to the gallon - even taking into account the smaller US gallon they should be able to improve on that.

Nice bike (there, I said it):

It's an electric scooter - and for once, someone's come out with electric transport that isn't crippled and hideous. OK, the top speed is 100kph - but it's a scooter; they're usually speed limited to less than that anyway. 0-50 in 3.8 seconds. Range is a little low at 110Km, but for commuting to work or running errands in town it would be ideal.

The video on their website ( http://www.vectrix.com/live/uk.php ) is quite interesting; the number of parts in the bike is about a tenth of an equivalent petrol powered bike; I've not found anyone willing to divulge a price yet though !

Why can't we be like the Swedes?

Low Energy Lighbulbs

2008-03-08T10:14:00.003Z

Huraah!!! I have finally replaced the last incandescent bulb in my house. The reason I took so long is that it was connected to a dimmer switch which have been a real problem for low energy bulbs. Homebase have finally started selling dimmable low energy bulbs made by a company called Varilight.

The bulb was a lot more expensive than an ordinary low energy bulb (£11.99) but I had wanted to replace the incandescent bulb for a long time and I expect the price will start to drop sooner or later. The bulb works pretty well with the dimmer although it take a significant fraction of a second to adjust so if you change the dimmer to quickly the light increases or decreases in sudden steps.

Overall the bulb is good but I think the price needs to come down before they'll really start selling.

Cool Looking Zero Emission Car!!!!!

2008-03-03T10:23:00.006Z

The subject of why alternative fuel source cars look like plastic bricks has come up a few times on this blog. Antony is particularly passionate about the subject, often flying into extreme rants and demanding answers that we all want. This post should provide warm fuzzy feelings and calm all of our doubts about whether a cool looking car can be ever be environmentally friendly.

That great manufacturer of classic cars Morgan has developed a new vehicle it has called the Morgan Life Car (to be unveiled this month at the Geneva Motor Show). The Life Car motor is powered by hydrogen fuel cells and so only emits water. The Life Car itself however emits an look of classic elegance and style. The specs are not too bad: -

22KW motor
150 mpg
250 miles per tank
0-60mph in 7 seconds
100mph top speed.
50% energy recovered from regenerative braking

Air Powered Car pt2

2008-02-13T14:39:00.002Z

I while ago I posted a story about a French design for a compressed air powered car read it here.

BBC news have done a story on the development. The car should be on sale within a year and may cost as little as £2500 for a 5 seater. It can be refueled from a compressor in 3 minutes or plugged into a domestic supply overnight and refuel with an onboard compressor in 4 hours. It can also burn various liquid fuels to preheat the air increasing it's range.

The company MDI is planning a range of products from sales of the actual motors, through a range of small cars and even including buses. Their website can be found here.

Read the BBC story here.

Here is an artist's impression of one of the small car models.

Cycling in London

2008-02-13T14:20:00.002Z

London is about to receive a £500 million investment towards improving cycling in the city. The scheme will include 6000 hire bikes. These will be available from docking stations where users of the scheme can unlock them, use them and then place them in another docking station when they are finished. This is similar to the Velib scheme in Paris shown below.

The scheme will also include 12 new cycling routes as well as clearly marked bike zones linking parks, waterways and key destination around the city. The aim is 5% of all journeys in London being made by bike by 2025. Personally I think that 5% in 17 years is pretty unambitious and that it will take a hell of a lot more than £500m to change the way Londoners travel. However I have seen the system in Paris and it was very popular so it may take off (assuming Londoners don't steal or vandalise all of the bikes).

Renewable Suber Grid pt2

2008-02-07T13:15:00.000Z

In August 2006 I wrote a post about a plan for a renewable energy super grid covering Europe and North Africa read it here.

The plan is now going ahead. The company behind this is the Trans-Mediterranean Renewable Energy Company (TREC). The plan is to build commercial concentrated solar power stations in North Africa that would sell electricity to Europe while simultaneously desalinating sea water as a by product of energy production.

Germany and Algeria have already reportedly signed a deal to lay cables stretching as far north as Aachen on the German-Belgian border. read more here.

Excuse me my good man this wine is errr.....bagged.

2008-01-20T19:37:00.000Z

One of the areas of environmental concern that is thankfully gaining increased attention is the carbon footprint of food production and distribution. Many producers are now starting to reduce packaging in their products while retailers are starting to make more local produce available (there is still a very long way to go but it is a start). Now changes are coming to that most traditional and civilised of packages, the wine bottle.

Australian producer Wolf Blass have started to use PET plastic bottles while Banrock Station are using my least favourite packaging the infamous Tetra Pak. However the prize for ingenious packaging must go to Arniston Bay with their resealable bag. They claim the bag uses 80% less of a carbon footprint than glass bottle. It also uses 90% volume in landfill (for those too damn lazy to recycle) and can be taken to public events where glass is not allowed. All this may be true, it may also be a good thing but it does not bode well for the traditional images of the snooty wine waiter, the dust covered bottle in a musty wine cellar, the scrunch of a champagne bottle in a silver ice bucket or the homeless person reduced to drinking blue nun or black tower from a bottle inside a brown paper bag. Oh well here is a picture: -

new battery tech

2008-01-10T12:46:00.000Z

Silicon nanowires have been used in a lithium battery to increase the capacity by a factor of ten - should lay waste to the 'milik float' arguement against electric cars.

hybrids, solar and google

2007-11-28T15:27:00.000Z

Google are getting into the renewable energy market by investing (through google.org) in solar, and in hybrid cars.

here's a link to the stats on one of their hybrid cars - this one has been fitted with an extra battery to improve performance.

http://www.google.org/recharge/dashboard/car?car=Machu%20Picchu&evy=3&evd=20071128&evt=000000

Note the MPG is a rather pathetic 54.4 - which is about what we get from our petrol C2. Shockingly the average MPG for an american car is 19.8 - this presumably is why the americans think the Prius is great, where as the rest of the world views it as a waste of space, or more charitably, a testing ground for mass production and marketing of electrically powered cars. Some little diesels can get at least /double/ the milage without the complication and cost of having batteries and generators on board.

Gas Fire

2007-10-24T21:14:00.000+01:00

Our gas fire broke last winter and we've just got round to thinking about getting it replaced. Gas is more efficient than electricity for heating, as the combustion is done at the point of use. Power stations on the other hand use heat to turn water into stream, drive turbines which drive generators, which send electricity down miles of cable just for you to turn it back into heat again. The generators are typically 40-60% efficient, and a further 6-8% or more is lost in the power cables and substations. (see here for more info)

Clearly then, the sensible choice is for us to replace our gas fire with an electric one and just not use it. We've been quoted £1600 + £400 installation for a gas fire, and £200 all up for an electric one. This includes a fireplace and mantle (£700 for the gas one). This isn't just about choosing the one that is most efficient, or makes most financial sense - this is about not actually owning sufficient money to buy the environmentally more friendly option.

Hanbury Hall and the national trust

2007-09-25T17:06:00.000+01:00

The national trust are going all green - as a conservational body they approve of the idea of reducing their impact on the environment, so they are starting a number of 'green' initiatives. One of which is a green energy tarrif in association with npower. Another is using renewables where possible.

I spotted this anomoly at Hanbury Hall - I couldn't find out much about it, but it does look rather incongruous seeing the ultra modern thin film solar panels, mounted on a 300 year old wall in front of a 500 year old house:

I /think/ its for powering a fountain - if anyone figures it out for sure, let me know !

The last horse finally crosses the finishing line

2007-09-14T14:14:00.000+01:00

According to Professor John Marburger scientific advisor to President Bush, climate change is almost certainly due to the activities of mankind and we need to start reducing CO2 emissions. President Bush is going to invite leaders from major nations to the White House this month to discuss the problem.

Thanks for the timely response guys.

US energy policy

2007-08-31T09:59:00.000+01:00

According to this, Carter came up with a energy policy proposal in 1979, specifically to prevent the US from having to go to war with the middle east to secure oil. Naturally it was opposed by many, and led to the bin Laden family essentially getting Bush2.0 in as the presedent.

oil subsidies

2007-08-31T09:35:00.000+01:00

Just found this article detailing the extent of the US oil subsidies. It boils town to tax breaks - the oil industry gets taxed at 11%, other industries at 18%, which if you do the math comes out to about $6billion. This clearly doesn't square with the $16billion mentioned below - which demonstrates the saying that there are lies, damned lies and statistics :-)

Wozniak Green Plans

2007-08-31T09:18:00.000+01:00

Steve Wozniak, of Apple fame, is jumping on the green bandwagon in a big way. He's discovered the idea of building homes that require little or no power to heat. Some of his ideas are a little misguided (eg, he suggested in an interview that one should knock down energy inefficient housing and replace it with shiney efficient housing - neatly ignoring the aount of energy required to build a home, not to mention the landfill required to dispose of the old one), but it's excellent that someone in his position has publicly declared energy efficiency to be a Good Thing&tm;, particularly as there is a certain class of Apple customer who will do everything the Steves tell them to :-)

One facinating idea he's come across (and no doubt will invest in) is that of using a particular wood for your core building material. Southern Yellow pine has sap that melts at about 22C, so as the external temperature rises above that, an enormous amount of energy is absorbed by the wood to melt the pine - keeping the internal temperature down. Neat idea - there's a few complications that I see - eg, sap tends to dry out over time, so it may lose effectiveness over time. Also, many people are allergic to pine sap, and as it evaporates (which surely it must if it becomes liquid) the house is going to be infused with vapourised sap. Not so good. Perhaps a synthetic version could be produced, with the working fluid sealed inside the structure of the building.

Oil industry in US

2007-08-06T10:16:00.000+01:00

Finally, the oil industry is getting attention from the US government. For all those people who bleat on about the millions of pounds of subsidy that renewable energy companies receive, here's an extract from the BBC news site today:

"The draft law details support for "clean" energy sources like biofuels, wind, solar and geothermal resources. It would withdraw some $16bn (£8bn) in annual subsidies from the oil industry."

Obviously, it is opposed by Bush, who is entitled to veto it, but at least it's an indication that people who matter in the US government are starting to realise that there are other ways of generating energy.

Sixteen billion dollars is quite a lot of money, though a tiny fraction of what has been spent invading the middle east in recent years to support America's oil addiction.

Wind Power For Campers

2007-07-22T20:06:00.000+01:00

I recently made a post on this blog about inflatable wind turbines. Trudy commented that it would be nice if there was a smaller version for campers. Orange clearly thought the same thing and commisioned a prototype tent mounted wind generator. The resulting device charges up a battery which in turn can charge up another device. Here's a picture: -

The good news is that it only weighs 150 grammes.
The bad news is that to generate enough energy to fully charge a mobile requires 24 hours of 12mph wind (I guess it won't run a cool box).

Still it is only a prototype and may improve. Find out more here and here.

Tesco improves carrier bag policy

2007-06-13T10:46:00.000+01:00

Tesco have improved their drive to reduce plastic carrier bag use. They have finally realised that there is no point in including carrier bags in home deliveries that already come in tough reusable crates and now offer delivery without them. I am a little surprised that it took them this long to work that out but well done all the same.

In the mean time I have signed up with Abel & Cole that deliver all of their food in re-usable boxes that are collected by the delivery guy next time they arrive. (I hope you enjoyed the wine Tony).

Inflatable wind turbines!!!

2007-04-25T06:25:00.000+01:00

A company in Canada called Magenn Power have developed a lighter than air inflatable wind turbine called MARS (Magenn Air Rotor System). I love conventional wind turbines and hope to see many more spring up across the country (especially outsde the homes of countryside alliance members). However they are not exactly portable. The Magenn system would allow a 4KW turbine to be packed into the boot of a family hatchback and be deployed anywhere with speed and ease. They are planning version capable of 1-2MW. These can be used for anything from the supply for a small town to power for emergency aid locations. They also have little or no chance of killing birds because they have no long blades and they are bouncy. Magenn's website is here.

Solar powered sausages

2007-04-25T06:04:00.000+01:00

Spring has arrived with a vengance and summer is clearly not far behind. With such wonderful weather many people are starting to have barbeques. While I will gladly admit that charcoal and gas powered barbeques are not that important in the grand scheme of planetary climate change it is still possible to take the green option. The technology for solar cookers is not new or complicated and has been used in countries around the world. This is useful in places where firewood is scarce and it also removes smoke from cooking fires which kills millions every year. However this is the first time I have seen a solar cooker targetted at the European barbeque market. A Swiss company have prduce a solar grill based on a simple parabolic mirror. It requires no gas, wood or charcoal only a reasonably sunny day (which we get even in the UK). It is also reasonably priced (about £120 plus postage and packing). You can find out more and order here.

Air Powered Car

2007-03-29T14:54:00.000+01:00

A french company called MDI (Moteur Developpement International) have developed an engine powered by compressed air and a car for it it to go in. The car called the MiniCat should sell for about £5,500, have a top speed of about 70 mph and be able to cover about 125 miles on fully charged tank. The cost of charging a tank of air should be about £1 and could be done from home or fuel stations. This is hardly a performance car but it is a very economic and practical solution for everyday use.

Tetrapak attempt 2

2007-03-12T22:11:00.000Z

Well, I wrote a short blog about how to recycle tetrapaks - you know, those little boxes that spill orange juice over you every morning. Sadly, it went the way of many things blogger, and disappeared. Poo. Anyway, there's an address of a specialist recycling place on the tetrapak website to post them to once they are empty. Most councils wont touch them as they are a made of several different materials all laminated together. I'd be interested to know if the energy you have to put in to recycle them is more than that required to make a new one - I suspect it is, but saving landfil is usually a worthy aim.

Could just burn the damn things I guess.

Are they taking this seriously?

2007-03-04T09:18:00.000Z

The government has just allocated £500,000 to grants for domestic renewable energy projects. I can't help but feel this amount shows a less than total commitment to renewable energy and domestic micro generation. To demonstrate how woefully inadiquate this allocation heres what happened: -

Greenpeace has produce a short (18 min approx) film about decentralised combined heat and power systems. It explains problems with the current centralised system that is used in the UK. It also shows some fantastic examples of decentralised multi-fuel combined heat and power systems being used elswhere in Europe. Such examples include: -

Systems that get 95% efficiency as apposed to the british average of 35%.
Powerplants that supply thousands of hectares of greenhouses with heat and CO2 as fertiliser.
Powerplants that use multiple fuel types including locally produced biofuel.

More on the Tesla roadster

2006-12-27T12:44:00.000Z

The BBC ran a story on the tesla roadster recently - there's speculation that it'll be available in the UK for about £50,000 in 2008. Start saving :-)

Carbon Trading

2006-12-22T10:48:00.000Z

Ebico do a handy online CO2 calculator which takes your energy usage details and has a guess at how much CO2 you produce - in my case, it's about 6 tonnes per year. They then go on to suggest that you buy CO2 credits to cover it. I'm not entirely convinced by that - the theory is, because you are buying the credits from the general industrial trading scheme, you are capping the amount that industry as a whole is allowed to produce. But the caps are fairly generous, and people wouldn't be selling them if they needed to produce that amount of pollution. And if a company starts polluting more, who's going to stop them - or measure it precisely enough to prove it ?

I would have thought it would be far better to spend the money on renewables schemes, or planting trees, or sending Goats to Chili, or on a few low energy lightbulbs - otherwise you're just lining the pockets of some market trader with no net practical outcome. In particular, a quick google for 'carbon scheme' came up with a stack of articles entitled 'carbon scheme doomed' and similar.

Recycling

2006-12-22T09:43:00.000Z

A report has come out recently suggesting that recycling is saving 10-15 million tonnes of CO2 per year, and that we are now recycling nearly a third of rubbish. A couple of years back, there were claims that recyling was 'burning trees to reuse trees' - ie, that it was pointless and we should just make stuff and put it in landfill. I suspect the people making those claims are the same ones moaning about new landfill sites. To be fair, I think their arguement was based on people driving 5 miles once per week with a few newspapers to recycle, which is clearly daft.

Our council are apparently going to replace all our wheelybins with compartmentalised ones - to help lazy people sort their rubbish. One of our neigbours always fills their bin to the brim - there's usually a wadge of paper or something recyclable or compostable preventing the lid from closing - and there's only one person in their houshold. We've got a baby (about the most un-environmental think you can do!) and we only produce a third of the rubbish - mainly just through sorting out paper, glass and cardboard. The new scheme claims to take plastic bottles as well - excellent news as there hasn't been anywhere local that could do that - and I'm not going to drive miles to the nearest plastic recycling plant!

Carbon neutral housing

2006-12-15T15:46:00.000Z

The government has finally made some attempt to change the building standards in the UK to be more ecologically sound. This is good news as there seems to have been little improvement in housing technology in the 100 years. A new proposal from Communities and Local Government secratary Ruth Kelly will require new homes to be carbon neutral by 2016. Houses will also be given a star rating for energy efficiency and zero emmision homes will be exempt from stamp duty. It is hoped this will act as an incentive for property developers.

Housing accounts for 27% of the carbon produced in the UK so this move could be a major part of the government's attempt to reduce carbon emmisions by 60% by 2050.

Electric car cont'd

2006-12-14T09:39:00.000Z

Found an even nicer looking electric car - the Tesla Roadster.

How annoying it this ? According to the FAQ, they are built by Lotus in the UK (thought the backend looked familiar) and shipped over to the US. They have no intention whatsoever to sell them over here *groan*. For a performance car, they're not even that expensive - $92,000 .

Fetish

2006-12-12T22:25:00.000Z

245 bhp

0-60 in 4.3 seconds

range about 200km

Looks, well, rather nice I think. It's the venturi fetish - costs about £300k or thereabouts. Oh, and it's electric.

Yup, you read right - someone has built a proper electric car that's road worthy, isn't just 'not slow' but actually 'really fast' and looks like a proper car. OK, it looks like a proper sports car, but the point is, it doesn't look like one of those stupid concept cars that are designed to look futuristic and end up looking like something from either thunderbirds or the teletubbies.

That's a real pet peeve of mine - just because a car uses an electric power source, why on earth should it look like anything other than a normal car ? No, the designers insist on making them look completely stupid.

There's a film coming out called who killed the electric car, looking into why GM crushed all their electric cars. Basically the public think that all electric cars are milkfloats, requiring 16 hours to charge, range 30 miles and top speed of 5 mph. The fact is, since the 1890s when the first electric cars were about, the technology has got far, far better than that. Even in the early 1900s, 20mph was quite normal for an electric vehicle, which was comparible with internal combustion driven cars at the time. Now, they are at least as good in most respects - just the cost of the batteries to sort out now !

And before anyone asks 'filling up a petrol car is really easy' - well, if you're out and about, that is true - however, you can't fill up with petrol at home, or at work. Swings and roundabouts I guess, but if I could plug the car in for a few hours and get 200 miles in the tank, well, that's as far as I really want to drive in a day so that would be enough.

speeding ticket

2006-12-12T20:53:00.000Z

Just discovered an electric car in the US recently got aspeeding ticket. It is suspected that it's a publicity stunt, though it's a good'un. mygreenwheels.com is a good looking uk based blog about electric transport; headover and take a look.

On the same site is a list of electric cars which kind of proves my earlier point about how stupid people make them look. There are about three or four on there I wouldn't be ashamed to own; the rest look utterly ridiculous - imagine the smart car with all the style removed, crossed with that BMW motorbike with the roof and you'll get an inkling...

Solar generation getting more cost effective

2006-12-12T20:19:00.000Z

The payback time on photovoltaics is getting better. Not, you might thinkk, because economies of scale are making the manufacturing process cheaper. Not because they are getting more efficient. Nope, it's because the unit cost of electricity generated by other means is going up *groan*.More here.

I spotted a letter in the guardian today - complaining about the 'hidden' CO2 emmissions of wind turbines. Yup, the anti wind league is now bleating on about the energy used to make the 'wretched things' - for example in the concrete bases. Funny that, what do coal fired power stations use for foundations then ? I don't think they publish the enbergy payback time for fossil fuel plants.

Abandon hope. We're doomed.

2006-11-24T11:25:00.000Z

Tom DeWeese ( the president of the american policy centre ) said:

"To save liberty in America, Sustainable Development must be stopped."

"And I will tell you now, if you want to keep your guns, your property, your children and your God… if you love liberty… Then Sustainable Development is your enemy!"

Obviously 'Sustainable Development' could have been replaced with almost anything. Simply slot in your least favourite religious, racial or idealistic group and repeat. Still, this seems to be official American policy now. (insert favourite deity) help us all.

Energy Statistics

2006-11-14T20:49:00.000Z

From the Ecotricity website:

"It is worth noting that a 1994 briefing note from the Parliamentary Office of Science and Technology to the Welsh Affairs Select Committee identified that each unit of electricity produced from fossil fuels, such as coal, results in excess of 860g of carbon dioxide, 10g of sulphur dioxide and 3g of nitrogen oxides being produced."

Impovements in solar power

2006-11-14T10:53:00.000Z

The problem with solar panels is that they cost too much and produce too little electricity per square meter. An example of this problem can be seen with major high street stores selling panels for £10,000 that will save £200/year. Most consumers don't want to spend on a micro-generation system that will pay for itself in 50 years (if it lasts that long). To be commercially viable pv solar panels need to undergo a dramatic reduction in cost, a dramatic increase in efficiency or both.

Researchers at Lawrence Berkeley National Laboratory have created solar panels that generate from a greater range of the EM spectrum. By doping a zinc-manganese-tellurium alloy with oxygen atoms they have produced a solar panel that responds to lower energy photons. This panel has an estimated efficiency 45%. Find out more here.

Old smoke detectors

2006-11-11T20:14:00.000Z

We've had a smoke detector fail. I'm sure it's not 7500 years since it was installed; that being the half-life of the radioactive material they use to make them.

So, what do you do with a busted smoke alarm ? Apparently the best thing to do is throw it in the rubbish bin - that seems to be the recommended practice. The radioactive material costs about £1000 per gram, so you can imagine how little of it there is in the smoke alarm (clue: about 0.0002g). Allegedly it's even safe to swallow it - it doesn't get absorbed by the gut as it's not soluble in water or fat, so apart from a few stray gamma rays passing straight through you, there should be no harm done.

Still, I'm not entirely comfortable with chucking it into landfill - or even incineration.

Let's go fly a kite

2006-10-22T12:25:00.000+01:00

Researchers in Italy have developed a new a form of wind turbine called KiteGen. The vertical axis turbine uses power kites. The kites are computer controlled by winches that are able to adjust the altitude (up to 2000m) and orientation continually to give optimum performance. Also with the assistance of radar the kites can avoid aircraft and even birds. The researchers believe a 100 metre diameter KiteGencould provide up to 500 MW at about £1 per GWh, the current average cost for electricity generation in Europe is about £30 per GWh. They also envision a KiteGen 2000 metres in diameter that could generate 5GW.

Here is an artist's impression: -

Solar stuff

2006-10-20T16:54:00.000+01:00

Mini solar update, from solarbuzz.com - Corus, you remember, British Steel that sold most of itself to a Dutch consortium and then sold itself in its entirity to an Indian firm - they are going into the integrated solar roofing market with PowerFilm

BP are investing heavily in the Chinese solar market

Cardiff is the new home of G24 Innovations, who will be manufacturing very high efficiency solar panels

So despite the lack of interest from Westminster, the market for renewables in the UK is looking better.

I've discovered that having a 2kw electric heater in a 2.5m x 3m shed, with all the insulation I've put in, is serious overkill; it went from being freezing cold to unbearably hot inside two minutes. It seems that my PC chucking out about 150W, is more than enough to keep the room comfortably warm.

Tesco's carrier bag craziness

2006-10-18T21:52:00.000+01:00

Tesco have recently begun a campaign to reduce the number of carrier bags people use. They have a launched television adverts containing famous people transporting their shopping in alternative containers that are in some way humorously related to the line of work that made them famous (Whoever thought of showing Alan Titchmarsh transporting his shopping in a wheel barrow is clearly a genius.). They are also offering extra loyalty card points to anyone bringing their own bags into the supermarket.

Don't get me wrong, this is a good thing and I applaud any effort to reduce our use carrier bags. The environmental damage caused by discarded carrier bags cannot be underestimated. While in Tenerife I heard about a turtle that had been pulled out of the ocean with 5kg of plastic bags inside it (It is surprising how many millions of carrier bags are estimated to be drifting through the worlds oceans and also how similar they appear to jellyfish if you are a hungry turtle.).

What I don't understand is why if they are so keen to reduce the use of these bags does the Tesco online groceries always arrive in carrier bags despite being in reusable crates. Why also do their shiny new self service checkouts force you to use their carrier bags. I understand that these checkouts use scales to detect when an item has been put in the bag but if the scales where tared when you press the start button you could put you own bag own the scales beforehand.

I have searched my local Tesco's as well as their website and have not found a place where I can post a suggestion to have this changed. Any ideas?

Richard Branson hurls cash at environment

2006-09-22T11:45:00.000+01:00

Spotted this piece on the BBC today - Sir Richard Branson is apparently going to hand over all the profits from his travel businesses to go to environmental research, via a company called Virgin Fuels - in the region of three billion dollars. Looks like they're starting off with ethonol etc sourced from biological processes - makes sense, as that could easily replace diesel in his trains, for example. Some prop drivel aircraft (see here) can run on a bio-diesel blend already, so with a bit of research cash it could be used for shorthaul flights too.

Well done Richard Branson, for having the courage and the cash to make a stand on the environment. Lets hope that a few more multibillionaires have the same idea; clearly the governments aren't interested so as usual scientific progress is up to a few people with the will and the cash to do it.

Now if someone could bung an odd million or so towards equipment for the Great Ormond Street neonatal unit, I'd be really happy :-)

Greenpeace looses its taste for juice pt3

2006-09-04T22:45:00.000+01:00

Here is NPower's explaination. They were trying to correct an error in the government calculations for reduced UK carbon emmisions :-0

---------------------------------------

Good afternoon Mr Payne,

Thanks for your email.

Earlier in the year all European countries published figures for reductions in the amount of carbon dioxide (CO2) emitted from power stations. However, the UK Government miscalculated its figures for the basis of these reductions. As a result npower, together with other energy businesses, decided to initiate legal action against the European Commission to get approval for this major error to be corrected.

Although Greenpeace understands our position, they are completely opposed to any increase in the level of CO2 emissions. On this fundamental point of principle we have been unable to find common ground and, as a result, the formal relationship between us will end in August.

Although Greenpeace will no longer formally endorse Juice, they will be happy to recommend it as the best non-premium green electricity product.

Trust this has answered your query.

Regards.

new solar panel manuf facity

2006-09-04T12:55:00.000+01:00

A few people have figured out how to print solar panels, and with a little backing from people like the founders of Google and Swiss Re.

http://www.energybulletin.net/19262.html

They hope to get up and running next year, producing panels at about a tenth of current prices. How long then before we can actually /afford/ (as cash stapped proles) to use solar extensively for domestic power production ?

Tornado powered ?

more ski

2006-08-31T10:44:00.000+01:00

Found a bit more about Les Gets and their solar powered lifts. They claim to have a number of envi9ronmentally friendly policies, frmo the elimination of cars to managing water supplies more effectively. Here is their website.

Cynics might say that the ski resorts are jumping on the environmental bandwagon and duping 'rich' punters into staying somewhere the wouldn't otherwise stay. Every little helps though, and it would be nice to go boarding in a mountain that doesn't smell of diesel...

That's another pet peeve of mine - why is skiing seen as a rich man's sport in the UK, whereas in countries with mountains it's just what people do in the winter to keep themselves amused ? I blame the british ski club...

Greenpeace looses its taste for juice pt2

2006-08-22T23:58:00.000+01:00

Here is the reply from Greenpeace

Hello Colin,

Thank you for your enquiry regarding Greenpeace's relationship
with Juice and npower.

As you know, for the past five years we have been working with
npower to promote Juice, a green electricity scheme linked to
offshore wind. Partly as a result of Juice the UK's first offshore
wind farm was built at North Hoyle off North Wales.  The green
electricity market has also been transformed and now several
non-premium tariffs are available.  So we can be pleased with
what we have achieved in campaign terms through the relationship
with npower.

Offshore wind is now on the way to becoming established as an
energy source in the UK.  Npower have plans to build a second
farm next to North Hoyle and a third, much bigger one, in the
area over the next few years.  Gaining public support for
offshore wind through Juice greatly helped to get the first wind
farm under way, however such campaigning and our involvement
should not be necessary in order to get the subsequent projects
built.

In addition, we learned recently from npower that they have
decided to join with other electricity generators to take the]
UK Government to court to try to secure an increase in their
emissions allocation under the European Emissions Trading System.
In other words, they want to be allowed to emit more carbon than
the Government wants to allow them.  At a time when the UK is
off course o meet its carbon targets, and when scientific news
on climate change is becoming ever more alarming, we do
not think that this decision by npower is justifiable.

In the light of this court case we have now decided to end our
formal partnership with npower and, therefore, our pro-active
promotion of Juice.  We have given npower notice of termination
of contract. This does not mean that Juice has suddenly become
a bad product.  We continue to believe that it is the best non
price premium green electricity scheme on the market, and will
continue to recommend it to people contacting us to enquire
about green energy.  I personally get my electricity at home
from Juice, as does our Executive Director, and we have no plans
to switch suppliers.

I hope that helps,

Truly fantastic news

2006-08-21T17:41:00.000+01:00

I know many of you come to this blog because of your concern for the environment and how our growing need for energy has become a threat to the world we live on. Tonight I want you to sleep soundly in your beds. We have no need to concern ourselves with the petty ideas of domestic solar panels or wind turbines. Biodiesel and biogas plants are redundent. Fossil fuels and nuclear power can be placed in the dustbin of history. Rejoice brothers and sisters for the holy grail of energy is in the hands of man at last.

A company called Steorn have produced a limitless energy supply with no impact on the environment and an effective efficiency greater than 100% !!!!!! They do not explain how it works or what it looks like and they have not had it verified by any scientist whatsoever. They also undertsndibly claim that their idea "represents a significant challenge to our current understanding of the universe".

I am confident that within the next five years the worlds energy problems will be solved giving us time to abolish war, famine and disease as well as invent jetpacks and meals in pill form.

Greenpeace looses its taste for juice

2006-08-19T19:46:00.000+01:00

I received a letter today from NPower Juice saying that they are aiming to increase their capacity to allow a further 50,000 homes to join. Juice accounts for a third of all green energy homes in the UK. This move would increase the total green energy homes in the UK by 30%.

The letter also says that Greenpeace are ending their partnership with NPower and no longer formally endorse Juice (although they still recommend it). I have emailed Greenpeace to find out their reason for this decision and will post their reply when it arrives.

Ski holidays

2006-08-15T21:22:00.000+01:00

Mid august - time to start thinking about a ski trip. Found this on babyworld.co.uk ; I've not checked it yet but if true it's a fab idea - ski resorts get lots of high-energy UV radiation so should be ideal for solar power :

"Thumbs up to Les Gets for taking steps to reduce the huge environmental impact skiing has by replacing its diesel generators with solar panels to power the ski lifts." ( from babyworld.co.uk )

Simple solutions to major problems.

2006-08-14T18:27:00.000+01:00

I studied engineering at university and now work in the IT industry. Some people might think that this would make me a fan of advanced technology. In all fairness they would be correct, I have a very fast PC, a mobile phone, MP3 player and even a GPS. However I am also a fan of appropriate technology. By this I mean technical solutions that are no more advanced than they need to be. This philosophy can best be summed up by two well known sayings: -

The right tool for the right job.
If it's not broke, don't fix it.

Why put nails in a piece of wood with the nail-o-matic ultra 4000 when a hammer is cheaper, simpler, doesn't require batteries and if properly cared for can last a lifetime? I suppose this does tie in with my time studying engineering. Engineers like to solve problems and they usually like their solutions to be simple and elegant.

It is when market forces come into play that technology is driven forward further than is really required. I want a phone that can make calls, send text messages and has a decent battery life. As a consumer, phone manufacturers want me to be able to stream TV clips over 3G networks because if I don't they won't be able to sell me their new phone. These market forces have given us a population desperate to buy gadgets that will only have 5% of their features used.

But what about people who can in no way be called consumers. People in the developing world are among the most vulnerable in the world. For people whose main concern is getting clean water and a steady supply of food appropriate technology can have a profound effect on their lives. It can help them solve problems such as transport, agriculture, home building, energy, water supply and purification. It can help them create successful and profitable industries. Because the technology is simple it is reliable and can easily be maintained, improved and replicated by local people using locally available materials. It doesn't need to be complicated, it just needs to work and it certainly never needs to be able to stream TV clips over 3G networks.

I used to walk past a bookshop on my way to work. It was called "The Intermediate Technology Bookshop". The books in the window fascinated me, they covered such topics as wind energy, water purification, solar cookers, human and animal powered transport, hut building, agriculture and international trade on a small scale. If an asteroid hit us and civilization went back to the stone age this shop would tell the lucky finder everything they needed to know to pick up the pieces and start again. The shop closed (perhaps I should have gone inside and actually bought something) to be replaced by a down-market Italian restaurant which also closed to be replaced by an empty shop.

Fortunately the shop was just one part of the Intermediate Technology Development Group who have renamed themselves to Practical Action (Their site is even more fascinating than the bookshop was). Practical Action are a charity that design and implement a range of solutions to problems faced by people in developing nations around the world. They also make many of their designs freely available online along with a host of technical information. Go on, try making some of them, I dare you. Practical Action have provided such life changing solutions as: -

Solar powered cookers.
Improved wood burning stoves that require less fuel and produce less smoke (Excess levels of cooking smoke kills 1.5 million people a year.).
Gravity powered rope ways in Nepal.
Composting toilets.
Wind and hand powered water pumps.
Bicycle trailers and bicycle ambulances.
Small scale electricity generation from wind, hydro, and biogas.
Solar water distillation.

Practical Action was founded by a guy called E.F. Schumacher, an economist who wrote a book called "small is beautiful: a study of economics as if people mattered" The book suggested that the current economic model of profit and progress that leads to large corporations was damaging both the environment and the developing world. It is hard to watch the news without at least considering that he might have a point. Schumacher attempts to befriend tree-hugging hippies and scruffy communists alike by suggesting that a better way for man to move forward is the use of intermediate technology based on communal ownership and regional workplaces using local materials. When he published the book 33 years ago it caused a sensation and although the developed world clearly didn't pay that much attention the methods he described are being used by people through the developing world (aided by many fine NGO's) to create improved resilience, prosperity and quality of life for themselves. It can put the lives and futures of people across the world into their own hands. It can help make a better world.

btw I have bought the book and may write a short review when I have finished (or not).

Renewable Super Grid

2006-08-14T17:38:00.000+01:00

The German government has recently commissioned a plan for a collaborative multinational electricity grid covering Europe, north Africa and some countries in the middle east. The grid would link together a range of large scale renewable energy generation plants of types most suited to the local climate. A simplified map is shown below.

As you can see the vast majority of plants on the north African coast are solar and rather than using low efficiency photo-voltaic panels they are using concentrated solar power. This method uses mirrors to direct sunlight onto fluid filled tubes which heat up and are then used to boil sea water. Many of you may remember that boiling water is often considered a good starting point for generating electricity. Boiling sea water is also a major part of de-salination so these plants would produce clean water as a by-product of generating clean electricity. The system is also able to store heat in rocks to continue production at night.

The grid is intended to use high-voltage direct current transmission and it is anticipated that it could transfer energy across 3000 miles (Morocco to mid-European latitudes) with only 15% loss. at about 4p/KWh delivered.

By adopting concentrated solar power north African countries could produce energy and fresh water, two things that are in ever growing demand in that region. 90% of the world's population lives within 3000 miles of hot desert and to supply the worlds energy needs would require 0.3% of that desert. The map below shows the potential for this method of energy production.

More about the plan can be found here and the executive report can be downloaded as a pdf here.

Toilet madness

2006-08-04T11:43:00.000+01:00

We've been looking for a toilet for a while now - our current one has a leaky cistern, and uses quite a lot of water per flush. It's also 20 years old, and it's huge and ugly.

However, almost all the retailers insist on selling complete bathroom suites - it is generaly more economical to buy a loo, sink and taps (and often a bath too), and then take the bits you don't want to the dump (after all, there is no market in second hand sinks) than it is to get just a toilet on special order. We were looking at toilets that were close to £200, and complete suites for less than that. This is just a crazy situation; it's so wasteful. The sellers try and lure you in with discounts on suites just to make sure consumers waste as many resources as possible.

Luckily, the new B&Q in gillingham now sells 'Toliets to go' for £50. Yup, that's what they call them. It's a complete toilet in a box, with all the cistern fittings etc. And if you just want a cistern float valve or other spares, they'll sell you that too. Amazing - the application of a bit of common sense. Now we've got the almost-as-silly situation where we need to pay a plumber probably double the cost of the loo to install it !

Power meter readings

Laptop: 60W
PC: 120W for the CRT monitor, 90W for the base unit
Upstairs Routing hardware: 40W (cable modem, wireless router, Lex PC for linking with work)
Downstairs Routing hardware: 24W (Voip phone, hub, wireless bridge)

The question is, is my 64W x 24hr energy expenditure on homeworking equipment more than what I used to use commuting by train up to london every day ?

Consumer solar ?

2006-07-31T16:00:00.000+01:00

Currys have started selling solar panels in retain outlets :

http://www.theregister.co.uk/2006/07/31/currys_offer_solar/

Maybe the start of a solar revolution ? We desparately need the price of solar to come down; it's just not affordable for anyone but the very rich at the moment; from a financial point of view it's crazy installing solar panels; you're looking at £10,000 to install enough to knock say £200 per year off your electricity bill. The panels are rated to last about 30 years.

Power meter

2006-07-17T11:35:00.000+01:00

I bought a power meter the other day from Doctor Energy - their customer communications could do with some work but it was only a tenner and turned up within about 2 weeks. It measures current, voltage and power factor, and from that derives total power consumption and cost. So the oxygen generator for Jamie uses about 400 W, the steriliser costs about 1p/day and the phone charger doesn't even register. I'll hook it up to a few different things to see what they use - I'm interested to see what the video and cable box consume when they are on standby; also my intenet gear is on all the time so must gobble up a fair amount over time.

Solar anyone ?

2006-07-11T15:03:00.000+01:00

Popped out on my bike for half an hour - two things struck me. Firstly, how nice and sunny it was. Secondly, on all of the thousands of new houses around here that heve been put up recently, there was not one with any kind of solar collector on - whether for hot water or photovoltaics. Seeing as the cost for the hot water collectors is only a grand or so it's amazing they don't bother putting them on from new - I'd have thought it was a good selling point that the heating bills will be about half what they would otherwise be.

And yes, I know ultimately the builders don't make that saving so they don't give a damn, but really, it's irresponsible.

Water usage

2006-07-10T22:00:00.000+01:00

Meat production uses an astonishing amount of water. Example: to produce a kilo of beef takes about 50,000 litres of water. Compare that with rice, which takes about 1000 litres, or chicken a mere 4,500 litres. As people are getting wealthier, they are eating more beef,so water demands are going up.

Apparently in the USA, the averge water usage per head is 500litres - in the UK it's 200 and in places like Gambia it's less than 10.

Must get the leak fixed in the header tank...

I recently discovered a fantastic site for anyone who wants to travel abroad but doesn't want to fly. The site is called "The man in seat 61" and gives vast amounts of info on how to travel from the UK to places all across Europe and the rest of the world by train and ship. There are lots or reasons to avoid flying: -

It creates a lot of pollution.
Some people are afraid of flying (although it is very safe).
Some people feel the journey is as important as the destination and an adventure in it's own right.
Lining up at the baggage check in followed by hours sitting in an airport then spending hours in a plane being served vile food while trying to avoid DVT and having the seat in front slowly crush your kneecaps only to have to make your way through passport control and then finding your luggage took a much more luxurious trip than you to a different continent IS NOT FUN.

I know many of the people likely to visit this blog would probably use the train where possible anyway. For those who wouldn't, give it a go. If you have to fly and are wracked with guilt over the pollution created to to get you where you were going you could try carbon offsetting. Some companies will plant and maintain trees for you. They will even calculate how many trees are required to absorb the carbon created by your journey (or household utilities). Some companies will offset carbon use through a range of different project. All they ask in return is that you give them your money.

Two such companies are: -

CO2Balance.com

The CarbonNeutral Company
(They take part in various carbon reduction schemes and also sell a range of environmentally friendly gifts and gadgets.)

Green electricity

2006-07-07T17:44:00.000+01:00

About 2 years ago I signed up with Juice. Juice is an electricity tarrif from npower. It costs their same as their standard tarrif but is produced from 100% renewable sources (mostly offshore wind farms like North Hoyle). It is also run in partnership with Greenpeace who ensure that the 100% renewable agreement is adhered to. They also give £10 a year for every Juice customer to renewable energy research projects.

I personally feel that the best future for electricity generation is decentralised generation by homes, offices, etc across the country. However it will take a while to happen and for people to save up for roof mounted solar panels and wind turbines. In the meanwhile signing up to one of the many green electricity providers is a good alternative.

Washing

2006-07-07T15:16:00.000+01:00

We bought a washing machine recently - we ended up with a Bosch one, mainly because it used 11 litres less water per wash than the hotpoint one. It also uses less electricity - and seems to wash a bit better than our old hotpoint as well. Sharon spent quite some time crawling round the floor in the showroom trying to read the efficiency data on each model; why don't they stick that data on the top ?!

It's getting good usage now - Jamie gets through quite a lot of nappies, and even factoring the cost of the washing machine into account, we should break even inside 2 years now that we have reusable nappies.

Portable Solar

2006-07-07T13:18:00.000+01:00

I recently bought a sunlinq set of solar panels with the idea of recharging various gadgets (GPS, MP3 player, phone, AA batteries, etc) when I was away from home and had no access to mains. The solar panels are light, flexible, waterproof and very durable they also fold down to the size of a thin book. The come with a range of of adapters including clips and a female car lighter socket which when combined with a 12v dc to 5v usb adapter can charge virtually any gadget you care to name. Unfortunately it is pretty expensive but comes in a range of sizes and costs (I went for the 12 watt one)

More info can be found here and a UK supplier can be found here.

This is a book with lots of simple tips for reducing your impact on the environment while often saving money.

Saving The Planet Without Costing The Earth

For those who are a little more hardcore in their environmentalism this book explains how to build a house that from building materials to energy generation and water collection and re-use will have virtually no impact on the Earth at all!

A book about keeping your house at a sensible temperature regardless of the weather:

The Solar House: Passive Heating and Cooling

House cooling

2006-07-05T09:12:00.000+01:00

Nick asked,"What is the most acceptable way of cooling down a house?"

I think the most acceptable way is to stop it getting hot in the first place! My shed now has foil-backed bubble wrap inside the roof and on the windows, which reflects heat back out - between the foil and the roof the temperature was about 46 degrees; in the shed it was a mere 30 degrees while the outside temperature was 27 degrees. In our baby's room I've put the same stuff on the windows (kitchen foil would do), as well as a blackout blind, plus we keep all the curtains shut on the side of the house that gets the sun. Oh, and open windows on both sides of the house to get a breeze through - even if there's no wind you should get a bit of movement through convection.

After that, paint the roof white (ideally silver), grow tall trees on the north and west sides, face the house south and have minimal size windows on the west side, use shutters and have an overhang over all the windows to reduce the heat coming in in the middle of the day. Um, not too practical for a rented house though :-)

Aircon ?

2006-07-04T11:48:00.000+01:00

Aircon isn't particularly environmentally friendly, but running it in reverse to do heating can be, as you are moving thermal energy from outside to inside rather than converting it directly from the electricity supply. Finally someone has released a device that works both ways, and doesn't have a stupid price tag.

Tony pointed out that if you have a wind turbine, this would be a completely free way to heat your house, particularly at night when it is often a) cold, b) windy c) you don't have anything much using electricity .

Windsave

2006-07-04T09:44:00.000+01:00

Windsave are doing mini wind turbines to fit on your roof for about £1500 - they generate 1Kw in a stiff breeze and thanks to some new planning laws are fairly simple to get approval for. When we get our big house in the country (ie, about 30years after I'm dead at current progress) maybe we'll get a couple.

lightbulbs

2006-06-30T11:55:00.000+01:00

How many compact fluorescent lightbulbs do you have ? We've only got six, but they are in the rooms we light most often. We still have halogen lamps in the kitchen; I /think/ they tolorate being turned on and off more often than CF lights, but that's a debatable issue.

Dr Matt Prescott wrote an article about them on the bbc site recently.

Food miles

2006-06-30T09:51:00.000+01:00

We've started getting an organic veg box delivered from Abel and Cole. They've got quite a nice website where you can place standing orders for various size boxes which they fill with in-season veg from local suppliers.

We started buying 'organic' veg when we got Jamie home, as we figured he'd had enough random chemicals in hospital without adding pesticides etc. In the supermarkets though, the tiny amount of organic stuff they have is typically imported from a long way away - Egypt, Israel and Argentina seem to be popular. It does seem silly to me to transport, say, butternut squash from 8000 miles away. Seeing as we live in Kent, it's even sillier to ship apples from more than 10 miles away - we accidentally bought some recently that had come from some far flung corner of Europe.

I read somewhere that Germany send as many potatoes to the UK as we ship to Germany - the bbc did a piece about it if you want to read more.

Kettle

2006-06-29T17:50:00.000+01:00

Here's an easy one - when using a kettle, put as much water in as you expect to use, and turn the kettle off when it's at the right temperature.

Here's the maths: for every degree temperature raised, and for every 1ml of water, you need 4.3joules of energy. So raising one litre by eighty degrees takes 1000x80x4.3=344,000 joules.

To figure a cost for that, convert to kilowatt-hours:

1 watt == one joule per second

1 kwh == 1000 joules used continuously over a period of 3600 seconds, ie, 3,600,000 joules

At about 10p/kwh, that's roughly a penny, to raise a litre of water to just under boiling point from room temperature.

Trouble is, if you actually boil the water, you use a lot of energy just to turn the water into steam - and you don't pour steam into your tea so it's just wasted.
