Energy Resources

Renewable energy is energy from sources that

• are constantly being formed

• humans can manufacture

• will take years to deplete

The decay of tiny marine organisms that accumulated on the ocean floor millions of years ago create

• uranium

• coal

• oil and natural gas

Electric generators work by

• converting oil into electricity

• turning mechanical energy into electrical energy

• turning the turbines in a dam

The fastest growing source of energy in the world is

• hydroelectric

• fossil fuels

• wind

Hydroelectric energy is generated from

• wind

• moving water

• geothermal heat

Inside the combustion chamber of a coal-fired power plant,

• the turbine sets the generator in motion.

• electricity is generated.

• burning fossil fuels release energy in the form of heat.

Which of the following is an advantage of using fossil fuels for energy?

• versatility in their use

• air pollution

A fuel's suitability is dependent on all the following factors, EXCEPT

• cost

• availability

• magnetism

Wind turbines convert the movement if the wind into

• electrical energy

• solar energy

• natural gas

Most of the energy consumed in the United States is used for
