"Oh my dear - you do look poorly. Come into my caravan and look at all the remedies I have. There must be something which will help you. Ahh - yes snake-oil - just the thing for a temperature. Oh...h! "You're so hot - better take two or three bottles. That's fifty quid each. Expensive? Worth it if it cures you deary"

Where have I met a sales spiel before similar to that of the MD of Renewable Energy Systems, Dr Mays (Act now to halt global catastrophe, January 3)?

Government's own figure for saving of the UK's CO2 emission by renewable power generation, mainly wind, is just 9.2 million tonnes per year by 2010.

This is less than the emission from a medium sized coal fired power station and more to the point is less than four ten-thousandths (0.0004) of global total CO2 emission and stands no chance of altering atmospheric CO2 concentration, still less deflecting climate change.
