The Green Edge

  CLEAN & GREEN

Electric bikes obviously consume energy, where a conventional bikes does not (provided we ignore the environmental cost of growing and processing food - see below). However, the amount of energy used is very small compared to a moped, motorcycle or car. Besides fuel, the only consumables are the batteries, and these can normally be recycled when life-expired. As for energy use, electric bikes typically consume fuel at an average rate of 100 to 150 watts of electrical energy, against 15,000 or so for a car (admittedly travelling faster, out of town at least). In terms of fuel consumption, an electric bike achieves about 800-2,000mpg (280 - 700 km/litre) (d). No other commercially available vehicle can match figures of this kind. If it's hard to place these numbers in your own lifestyle, a 100 watt electric light bulb burning for an evening uses enough energy to propel an electrically-assisted bike for 20 to 40 miles.
