Pros and Cons of Energy Resources

The energy resource that is most affected by change in weather is_____________?

• geothermal 
• wind
• nuclear
• natural gas

What are two advantages of geothermal energy?

• cheap and a lot pollution
• expensive and a lot of pollution
• cheap and little pollution
• expensive and little pollution

What is a disadvantage to Hydroelectricity?

• lots and lots of pollution
• Kills wild bird population
• Radioactive waste
• Increases potential for flooding 

If a business is considered to be "green", how could you add to the electrical power system? 

• use hydroelectricity
• add solar panels to roof
• use nuclear power
• use a coal powered generator

If a river is located in a deep canyon, and has  changing amounts of water , how can this be developed as an energy source?

• A dam could be built to store water
• A well could be dug to hold the water
• Wind turbines could be built on the banks.
• You could fish in the river.

Hydropower 

• produces no air pollution
• can be built in any location
• has no construction costs
• uses a nonrenewable resource

Which is an advantage of installing solar panels?

• Reduced amount of air polllution
• High cost to install
• Number of cloudy days
• Use of nonrenewable resources

Some power plants pump water down deep holes into hot rock. The hot rock heats the water, which turns the water into steam. The steam rushes back to Earth’s surface and is used to make electricity. This plant is generating which alternative energy resource?

• biomass
• wind
• solar energy
• geothermal energy

Why is burning fossil fuels harmful? 

• then we won't have any fossil fuels if we burn them all
• They can get extremely hot
• Increases the amount of greenhouse gases in the air
• this would destroy fossils

One benefit of geothermal energy is that ________________________________.

• a plant can be built ANYWHERE

• it doesn't cost a lot of money to build

• it can provide power 24 hours a day

• it harms ecosystems where it's built
