ES 9.2 Renewable Sources of energy

Energy source that uses moving air directly to spin a turbine. The only issue is that they provide an unsteady energy supply.

• wind

• solar

• hydroelectric

• geothermal

Energy source that uses the heat or light energy from the Sun to form electricity. It will not run out for billions of years but it is only available when the sun is shining.

• solar

• wind

• geothermal

• hydroelectric

Energy source that uses moving water to spin the turbine directly. Dams affect the natural spawning routes of many fish though.

• solar

• wind

• hydroelectric

• geothermal

A device which blades are turned by a force (that of wind, water, or steam).

• biomass

• generator

• turbine

• gasohol

____ energy comes from sources that are infinite like the sun, wind, and water, or from sources that replenish themselves naturally like geothermal and biomass.

• geothermal

• solar

• renewable

• generator

What is the greenhouse gas emitted when you burn fossil fuels?

• greenhouse gasses

• hydroelectric

• carbon dioxide

• turbine

Energy source that uses the heat below the Earth's surface to produce steam to spin a turbine. It is expensive to drill deep into the ground.

• geothermal

• renewable

• solar

• hydroelectric
