Something I and other wind energy folks have been saying for some time now. Rooftop wind turbines just don't make a lot of sense even if they are well intentioned.
Wind Turbine Grant Testing Urged - BBC - 07 Aug 08
"The Carbon Trust study says turbines in urban homes may not generate enough electricity to counter CO2 emissions created by their manufacture and use. It said grant schemes should consider whether the likely carbon savings of small wind turbines are 'reasonable'."
PDFs of the report, "Small Scale Wind Energy", and a technical supplement are available.
And they have a press release, "Carbon Trust Study Clarifies The Potential Of Small-Scale Wind Energy".
