In reply to the question asked by JC Joel (NCE 14 June) about the alternatives to nuclear power; the answer is not more coal, oil or gas. We must try more hydroelectric power, more onshore and offshore wind farms and more solar power.
And have we any tidal power yet? The Severn Barrage alone - if it is built - is calculated to provide 10% of our energy needs and there are many more potential sites around our coasts. Let us also make a start on wave power. We still have geothermal energy in reserve and on the other side of the coin, we are very wasteful with the energy we do produce. The throw away society never did make any sense.
