Renewable and Nonrenewable

All are examples of non renewable except

• Coal

• Natural Gas

• Hydropower

• Uranium (Nuclear)

What is a disadvantage of wind power?

• We have too many rainy days in US
• It is not always windy in some places
• Companies charge too much to make the wind blow
• The sun is not always out

Heat energy generated and stored in the Earth.

• Geothermal
• Solar energy
• Wind Power
• Electromagnetic 

An inexhaustible resource is 

• coal
• solar
• oil
• petroelum

What is a reason that nonrenewable energy sources are used?

• they are more expensive

• they are less expensive

• they pollute

• we will never use them all

Fossil fuels are considered nonrenewable because they

• produce pollution

• are no longer used by humans

• often contain microscopic animals

• take millions of years to form

What are the 3 main fossil fuels?

• Coal, Oil, and Gasoline
• Coal, Oil, and Natural Gas
• Electricity, Gasoline, Petroleum
• Coal, Oil, Non-renewable Resources

Which of the following is NOT an advantage of coal?

• It is very abundant
• It is relatively cheap
• It does not need much processing after it is mined
• It does not release any greenhouse gases when burned  

Which of the following is NOT an advantage of using wind as an energy source?

• Wind decreases the need to burn fossil fuels.

• Wind is a renewable resource.

• Wind does not produce air pollution.

• Wind turbines increase the availability of wind for energy in the future

Natural gas is a fossil fuel formed within oil fields and coal beds. What is an advantage of using natural gas as a form of energy?

• Burning natural gas releases relatively low emissions compared to other fossil fuels

• The stored energy in burning natural gas is less concentrated, so more needs to be burned

• There is a limited supply since natural gas is a non-renewable resource

• Burning natural gas tends to be more expensive compared to other fossil fuels
