Energy Resources

Wind Energy: the energy drawn from wind

windmills: wind energy ________ energy

wind turbines: wind energy electricity

Advantages: 1. renewable energy resource

2. does not produce any greenhouse gases

Disadvantages:

1. towers can ruin the beauty of the landscape

2. impossible to predict how fast the wind will blow.

3. wind energy cannot be stored (needs a backup)
