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.
