Read this the other day as I'm in the market for sparks-on-wheels.
Elec is 20% better than petrol. Or, it takes 80% of the energy to make one. Over a "lifecycle".
' the same report estimated that over its whole lifecycle, the electric car would still be responsible for 80% of the emissions of the petrol car. "
Sounds like a great deal, biiiig tax savings for a kinda-half-dacent reduction in CO2. If you're seriously green, keep riding that bike.
