So, How Much Power Could Solar Cells Contribute To The World?

Solar cells, also known as photovoltaics, use semiconductor materials to convert sunlight into direct electrical current. As of now, they provide just a small portion of the world’s electricity. Their global generating capacity is about 5000 MW, or only 0.15% of the total generating capacity from all sources. Still, sunlight could provide as much as 4500 times as much energy as the world currently consumes. Read more
