For now I'll spare commentary on the Honourable Leader of Her Maj's Opposition being a bit of a bandwagon chaser, and restrict myself to the turbine issue, which he in part is responsible for me getting all excited about, and shows that some caution is needed before rushing to be green.

Because to this point, I was pretty convinced these things were not a bad plan, though I had been, and still am, concerned on the ability of a domestic chimney handling the load. This, however, adds another dimension: "Trevor Butler, director of sustainability at the Building Design Partnership, says the kit amounts to little more than expensive gadgetry. “I would estimate the daily output of the turbine at roughly 1 kilowatt-hour per day,” he said. “The average price of electricity in London at the moment is 10p per kilowatt-hour. As the cost of the turbine is £2,600, the payback would be 71 years. The renewables can be seen as expensive gadgets — but they do raise awareness.”

Certainly something to bear in mind.
