Peter Coates, of South Huish, near Kingsbridge, writes:

With regard to Katie Reville's letter, Gazette, March 29, the cost of electricity is made complicated as the breakdown of costs is not clearly shown on our bills – this incidentally is something we should all be striving for.

The financial results of Centrica were shown in the Times about a month ago and these were one of the sources for my comments about renewable energy subsidies.

Consistently, we are told that the average bill is around £1,300 per annum – my comment of £110 per annum for renewable subsidy is possibly understated. Ms Reville's annual bill would only be £286 per annum if the subsidy were £20, seven per cent of her energy bill.

The problem of wind turbines and solar panels is that they only work when it is windy and the sun is shining. We are not investing enough in permanent supply whether it is nuclear, coal, gas or oil and are now in real danger of having continuous power cuts.

On the basis that you cannot store electricity, I would be interested to know how your readers would expect the continuous generation of electricity to be provided.
