Traditional solar cells only use up to 20% of the visible light they collect, and more efficient solar cells are too expensive for mass production. Now researchers at the US Department of Energy’s Idaho Laboratory have figured out a way to capture solar energy on the cheap: plastic sheets filled … [continued]
Renewable forms of energy such as solar and wind are notorious for being unpredictable. That may change with the advent of the Previento System, a new type of software developed at Oldenburg University in Germany. The software, which uses weather models from multiple weather reporting services, is able to predict … [continued]
What if you could drastically reduce greenhouse gases just by changing your eating habits? According to a new study by the University of New South Wales, farming kangaroos instead of sheep or cattle could lower national greenhouse gases in Australia by 3 percent a year.
