A new study, commissioned by the German government, has found that solar energy can help Europe can meet all its electricity generation needs and cut CO2 emissions from electricity generation by 70% by the year 2050
The study says that by harnessing the sun's energy falling on the desert areas of the planet, the use of nuclear power could also be phased out by the middle of the century.
Key to the proposal is the development of a solar-energy collaboration between countries of Europe, the Middle East and North Africa.
The study estimates that every year, each square kilometre of desert receives solar energy equivalent to 1.5 million barrels of oil. Across the world's deserts this equates to nearly a thousand times the entire current energy consumption of the world.
