"... the most ambitious solar project is in north Africa. The Desertec Industrial Initiative is a plan to build a vast network of solar power plants and wind farms, covering the desert and stretching for hundreds of miles, and connected to an advanced electricity grid that will carry power generated round or under the Mediterranean sea to feed Europe’s appetite for energy.
Desertec – backed by a coalition of more than 10 big name companies, including Munich Re, the German insurer, Deutsche Bank, utilities RWE and Eon and Siemens – is likely to cost about $400bn (€302bn, £262bn). If successful, the project could supply as much as 15 per cent of Europe’s electricity needs by 2050."
What I found interesting is Desertec's request for donations for the project via the web, see here. Desertec is empowering the individual to act through a validated message of need, yet the value needs to be made clear for the "call to action" to be advocated.
