Let's work out just how useful wind farms really are

Would it not be possible for your readers to have a credible cost analysis of wind power, embracing (1) capital cost of a typical wind turbine installed (excluding subsidies) and its maximum rated output, (2) life expectancy of turbine, (3) estimated cost of maintenance during service life, (4) minimum wind speed to activate turbine, and (5) the expected number of days per year when there will be insufficient wind to operate the turbine.

A separate analysis would be required for on-shore and off-shore installations.
