Kotaro Kawajiri and his colleagues, in an article in the U.S. journal Environmental Science & Technology, say many cold regions at high elevations -- including the Himalaya Mountains, the Andes and even Antarctica --receive so much sunlight their potential for producing power from the sun is higher than some desert areas.
Part of their study took into account the effects of temperature on the output of solar cells, and future work will take into consideration variables such as transmission losses and snowfall, they said.
Still, they said, the potential of high, cold locations is attractive.
The Himalayas, for example, which include Mount Everest, could be an ideal locale for solar fields providing electricity for the fast-expanding economy of the People's Republic of China, the researchers said.
