My experiences in installing a Bergey Excel 10kW turbine.
The Times ran a report on 20 Feb 08 entitled "Forget biofuel, try a car that runs on air" - see http://www.timesonline.co.uk/tol/business/industry_sectors/transport/article3399532.ece
Does anyone have any further insight?
I have recently come across this spreadsheet calculator, which may be a helpful tool to compare the costs of a number of alternative forms of heating. Unfortunately, the numbers are calculated in $ and US gallons etc, but I guess (for someone who is conversant with Excel), it should not be too hard to convert the spreadsheet for use in the UK?

The attached article appeared in Home Power Magazine April/May 2004 edition and provides a useful review of the African Wind Power (AWP) 3.6 grid-tied small wind turbine & SMA Windy Boy Inverter. It was written by Dr Bernd Geisler in a US context.
Home Power Magazine, the US journal for hands-on enthusiasts, has a useful article on wind turbines in the June/July 2007 edition. Written by Mick Sagrillo & Ian Woofenden, guru's of small wind systems, it provides an update of previous buyer’s guides produced by Mick Sagrillo.
A report from the US National Research Council suggests that Wind farms could generate as much as 7 percent of U.S. electricity in 15 years, but scientists want to spend more time studying the threat spinning turbine blades pose to birds and bats.
(N.B. I have not witnessed any bird or bat strike from my relatively small 10kW Bergey turbine. Mike Bergey tells me that, in over 20 years, Bergey have not had a single turbine returned for repair as a result of this issue. Likewise, this 22 ft diameter turbine has had no effect on local radio & TV signals. A combined Orange & Vodafone base station is located within 150m of the turbine).
In November 2006 we installed a Bergey Excel 10 kW grid-intertied system for domestic use on a 24m. guyed latticed tower. In the first four months of operation the system has generated 6,900 kWh (we would expect these winter months to be the most productive).
