OTHER ENERGY SOURCES
type of energy
description advantages disadvantages
Wind energy
Wind turbines use energy from wind to spin generator
1. No air pollution
2. Land below turbines – used to grow crops
1. Wind doesn’t blow all the time
2. Kills birds
3. Noisy & ugly

type of energy
description advantages disadvantages
Moving water
Hydro-electric power plants-water flows thru dam-spins generator
1. No fuel needed
2. No pollution
1. Can only be built where moving water is
2. Must have place where lake can form
