Just so you know, a study commissioned by the Low Carbon Vehicle Partnership, jointly funded by the British government and the car industry, found that a mid-size electric car would produce 23.1 tons of CO2 over its lifetime compared with 24 tons for a similar gas car. Emissions from manufacturing electric cars are at least 50 per cent higher because the batteries are made from materials such as lithium, copper and refined silicon which require much more energy to be processed. And as to ethanol, running maize in cars has only distorted the economics of agriculture; we are now staring straight into another artificially induced, government manufactured asset bubble.
