mdsolar (1045926) writes ""Amid polemics over rising electricity prices in Europe and the level of green energy subsidies in various countries, it is easy to lose sight of the fact that the growth in clean-energy generation is a huge success story.
Solar photovoltaic generation, known as PV, like wind power before it, is coming into the mainstream — at great environmental benefit.
Based on comparative life-cycle analyses of power sources, “PV electricity contributes 96 percent to 98 percent less greenhouse gases than electricity generated from 100 percent coal and 92 percent to 96 percent less greenhouse gases than the European electricity mix,” said Carol Olson, a researcher at the Energy Research Center of the Netherlands.
Photovoltaic generation offers several additional environmental advantages, Ms. Olson said in an interview.
“Compared with electricity from coal, PV electricity over its lifetime uses 86 to 89 percent less water, occupies or transforms over 80 percent less land, presents approximately 95 percent lower toxicity to humans, contributes 92 to 97 percent less to acid rain, and 97 to 98 percent less to marine eutrophication,” she said. Eutrophication is the discharge of excess nutrients that causes algal blooms.""
