The world is full of tradeoffs, and sometimes 'renewable power' activists fail to recognize that. Solar energy collectors must displace a tremendous amount of natural landscape to produce any significant amount of energy. And anything less requires a great deal of financial expenditures for very little and very inconsistent power.

Electric Vehicles

A vehicle with one or more electric motors for propulsion. In electric vehicles, the motion may be provided either by wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by linear motors. The energy used to propel the vehicle may be obtained from several sources: on-board batteries, on-board rechargeable energy storage system (RESS), on-board fuel cells, on-board nuclear energy or from more esoteric sources such as flywheels, wind and solar or from a direct connection to land-based generation plants, as is common in electric trains and trolley buses.

The reasons that electric motors are a good choice to drive vehicles are that they produce less air and noise polutions, they can be finely controlled, they deliver power efficiently and they are mechanically very simple. One widely used type of electric vehicles is golf carts.
