Harnessing some of the sun’s energy that shines on the deserts of North Africa and the Middle East would solve all of Europe’s electricity demands.
"The sun is the hidden asset of North Africa and the Middle East," says Gerhard Knies of the Trans-Mediterranean Renewable Energy Cooperation (TREC), a network of international scientists and politicians committed to solving Europe's energy problem. TREC’s mission, called Desertec, is to spin electricity out of sunshine.
Every year, 630,000 terawatt hours in the form of solar energy fall on the deserts of the Middle East and North Africa. Europe consumes just 4000 terawatt hours of energy a year. The benefits are glaringly obvious - so why aren’t affluent societies investing in this generous renewable resource? To read the full article, click mouse here.
The square at left is around the size of Austria. If that area were covered in solar thermal power plants, it could produce enough electricity to meet world demand. The area in the centre would be required to meet European demand. The one on the right corresponds to Germany's energy demand.
