Answer is blowing in the wind – really

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 energy crops on a grand scale or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University in the US. He says that currently fashionable "clean coal" - which involves capturing carbon emissions and sequestering them in the earth, and which is currently flavour of the political month here in Britain - is not clean at all.
