Roof-mounted wind turbines 'no help in reducing carbon' http://apocadocs.com/s.pl?1264010557
Roof-mounted wind turbines and solar panels are "eco-bling" that allow their owners to flaunt their green credentials but contribute very little towards meeting Britain's carbon reduction targets, according to the Royal Academy of Engineering.... Field trials carried out last year by the government-funded Energy Saving Trust found that the most productive building-mounted wind turbines in urban or suburban areas generated only £26 of electricity a year. Many of these turbines, which cost about £1,500, were net consumers of electricity because their controls drew power from the grid when the wind was low.... Professor King said that for wind turbines on urban homes to be effective, they would have to be so big that their vibration would damage the building. He said that installing microgeneration devices could cost £10,000 to £12,000 per home and reduce its emissions by only a few per cent. He proposed an alternative policy under which developers would offset the entire emissions of new homes by contributing £3,000 per dwelling towards a wind farm on a hilltop.
