Solar may cover the world’s electricity demand with 0.3% of its land area

Solar energy could theoretically cover the world’s electricity demand by just 0.3% of its land area. This is one of the main conclusions of new research by a group of academic institutions, led by Aarhus University in Denmark. The researchers claim that raw materials and land availability will not present real barriers to PV in its race to dominate the global energy landscape.

The scientists claim that, for an average annual generation for solar of 1,370 kWh/kW, 38 million hectares would be needed. They noted that the world has a total area of 13,003 million hectares.
