Report: Solar Could Meet All The World's Electricity Needs In 2050 Using Under One Percent Of World's Land | ThinkProgress
Highlighting the fact that a global switch to renewable energy is not just necessary, but doable, a new report released by the WWF concludes that the solar arrays necessary to meet all the world’s projected energy needs in 2050 would cover under one percent of global land area. Obviously this is a theoretical exercise, and 100 percent of the planet’s electricity needs are not actually going to be filled through solar. But several credible scenarios suggest that solar could provide about 30 percent of global total electricity in 2050, up from the 0.1 percent it provides now.
By going through the numbers, the Solar PV Atlas demonstrates both the practical feasibility of renewable energy, and the possibility of harmonizing solar energy with conservation goals:
