Turn fans down to reduce emissions
If just half of Britain's electric motors were reduced in speed by 10%, it would have the net effect of mitigating for the carbon emissions of 9.8 million cars every year. While this fact might not enthuse Jeremy Clarkson, it has a far more serious message and that is that governments subscribing to the Kyoto Protocol, and its greenhouse gas emissions reduction targets, continue to ignore the low hanging fruit that electric motor control presents.
