Renewable vs. NonRenewable Energy Review

What is one one disadvantage of hydroelectric energy?

• It doesn't work if you don't have volcanoes nearby.

• It doesn't work if it is not windy.

• It doesn't work if you don't have rivers or moving water nearby.

• It doesn't work unless you have plenty of fossil fuels.

Out of the choices below, which form of energy makes the most pollution?

• Hydroelectric

• Geothermal

• Fossil Fuels

• Only a few dams have been built

• They produce no carbon dioxide when making electricity

• They are cheap to build

Water stored behind the dam is known as …………..

• Dam
• Penstock
• Water reservoir
• Spillway

What type of energy is being produced when a dam is placed across a river and water is released to turn a turbine that produces electricity?

• Wind
• Geothermal
• Hydroelectric 
• Solar

Which of these hydroelectric dams has had a major impact on its surrounding ecosystems?

• DC

• Heat

• Mechanical

What kind of power does your house need to run on ?

• AC

• 10 V

• 540 V

What is an advantage of vertical axis wind turbine over the horizontal axis wind turbine?

• It can harness winds from every direction without the need to reposition the rotor.

• The blades are closer to the ground where the wind speed is higher.

• The tower is strong to handle the heavy equipment on top.

• The mechanical components are high off the ground so they don't have to be serviced periodically.
