Wind, water and sun beat biofuels, nuclear and coal for clean energy

摘要

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineer- ing at Stanford. And 'clean coal,' which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.
