Cooking on gas


With reference to recent correspondence (NCE 6 April) regarding the extent to which Britain's energy needs can be met from renewable sources, this surely depends upon the premium we are prepared to pay to eliminate CO 2 emissions, while avoiding the nuclear option.

Hypothetically, the whole of the UK electricity demand could be met by wind-power, provided enough storage were available to maintain supplies when the wind was not blowing, or blowing too hard.

For instance, hydrogen, produced while the wind blows, could be used in fuel cells or gas-turbines to maintain the supply when it doesn't.

No doubt, the cost would be enormous, but, if expense were no constraint, it's a possibility - at least in theory!

Another thought, though: would we be happy to see the country covered by windmills from coast to coast?
