Home wind turbines in UK warming the planet

Many wind turbines mounted on homes in British cities are contributing to global warming, not fighting it, according to a new study.
The study analyzed the likely performance of three of the most common household wind turbines in Manchester and Portsmouth in England and Wick in Scotland.

In many cases -- and across most of Manchester -- more climate-warming carbon dioxide is produced in the manufacture, installation and maintenance of the turbines than they save by generating "green" power over their expected lifetime.

"These studies have shown a large variation in the expected CO2 payback periods from a few months in good locations to situations where they never pay back, in poor locations," the report says.

Only those climate-conscious homeowners in the best locations in the two smaller cities studied can expect to save more carbon dioxide than their turbines are responsible for producing.
