• Geothermal

Water is stored in a reservoir, the penstock carries the water to the turbine, the rotating turbine generates electricity. This describes what type of alternative energy?

• Solar Energy

• Hydropower

• Geothermal Energy

• Wind Power

Wind energy is 

• generated from moving water

• starts with moving air and generates electricity

• starts with the sun

• comes from the earth

The poster shown below advertises tours of a power plant.

What is a negative aspect of using solar energy?

• the sun is not strong enough to provide energy for a long time

• solar energy can only be used during the daytime

• solar energy cannot be stored to use later

• it is expensive to transfer stored solar energy to another location

When learning new information about alternative energy sources, what is a good practice to use?

• never apply new information to your life

• always take what someone tells you as a true statement

• research ideas on your own to make sure you have enough information

• ignore new ideas and information if it goes against what you already know

If an energy sources is considered green, what does that mean?

• its emissions come out green colored

• it is better for the environment because it has little to no emissions

• it has more emissions and pollution than most energy sources

• they have recently been approved by the Environmental Protection Agency

What is an advantage of using wind and solar energy?

• they will not run out

• they will harm the environment

• they will produce emissions

• they will eventually run out

Geothermal energy is energy from 

• the sun

• heat from deep in the earth

• wind

• inexhaustable
