IT was interesting to read last week that your correspondent Steve Stuart has seen our “countless numbers of wind turbines swirling away all day” and questions why his electricity bills haven’t reduced.

I would suggest the reason why they haven’t reduced, is largely contained in Kenneth Burnley’s excellent letter on the same page.

The fact is that these costly, inefficient structures only “swirl” randomly for about 30% of the time, and thus also need conventional back-up power to supply us with energy when the wind either isn’t blowing, or blowing too hard.

So, they are only commercially viable to erect off-shore when the overseas operators are able to be paid three times the commercial rate for any electricity they generate.

The Government then passes the extra costs of these green subsidies to us, the consumer, via our electricity bills which thus lessens the prospect of any price reduction.
