Title: Alternative Energy Self Assessment
Course: 2016FA-MCO-115-401

Please read the questions and possible answers carefully. Provide the best possible answer.

Q: The power of the wind can only be used to generate electricity.
- True
- False
A: False
If right: Very good! That is correct, it can also be used to create mechanical power which makes mechanical devices work.
If wrong: The correct answer is false. It can also be used to create mechanical power which makes mechanical devices work.

Q: Hydrosolar energy is the term used to describe energy that comes from moving water.
- True
- False
A: False
If right: Wonderful! You knew that hydrokinetic energy is the term used to describe energy that comes from moving water.
If wrong: Incorrect. The answer is False. Hydrokinetic energy is the term used to describe energy that comes from moving water.

Q: Solar energy can be used to generate electricity, heat water, and as a source of heat for homes.
- True
- False
A: True
If right: This is correct!
If wrong: The correct answer is true.

Q: A dam is never used as a part of the hydropower process.
- True
- False
A: False
If right: Correct. A dam is often used as part of the hydropower process.
If wrong: The correct answer is False. A dam is often used as part of the hydropower process.

Q: A geothermal heat pump system takes advantage of ___________________________________________.
- the fact that temperatures remain fairly constant underground
- moving water can be used to create electricity
- biological matter can be used to create energy
- water can be used from oceans, rivers, or streams
A: the fact that temperatures remain fairly constant underground
If right: Very good! You knew that underground temperatures remain fairly constant and are generally cooler than the outside temperature in the summer and warmer than the outside temperature during winter.
If wrong: No, that is not correct. Underground temperatures remain fairly constant and are generally cooler than the outside temperature in the summer and warmer than the outside temperature during winter.

Q: Alternative energy generally is a term used to describe energy sources that do not rely on fossil fuels.
- True
- False
A: True
If right: Great!
If wrong: No, this is true.

Q: Biomass is biological matter that can be used as a source of energy and often refers to plant matter.
- True
- False
A: True
If right: Good!
If wrong: No, this is true.

Q: Both green energy and renewable energy would fit the definition of alternative energy.
- True
- False
A: True
If right: Great!
If wrong: This is true.

Q: Green energy would include burning fossil fuels to create electricity.
- True
- False
A: False
If right: Great!
If wrong: No, this is false. green energy must not have a negative impact on our environment. Burning fossil fuels creates higher levels of carbon dioxide in the environment.

Q: Plant matter burned for fuel is biomass.
- True
- False
A: True
If right: Great!
If wrong: This is true. Biomass refers to biological matter used as a source of energy. Biomass often refers to plant matter. It can be burned for heat or converted to biofuel.

Q: Thermal energy that is stored in the Earth is _________________ energy.
- geothermal
- hydropower
- hydrokinetic
- all of these
A: geothermal
If right: Good! Geothermal energy is, thermal energy that is stored in the Earth.
If wrong: No, that is not correct. Geothermal energy is, thermal energy that is stored in the Earth.

Q: Some people collect solar energy to heat water for bathing and to heat their homes in addition to generate electricity, while others collect it solely to generate electricity.
- True
- False
A: True
If right: Yes, this is true.
If wrong: This is true.

Q: In wind energy, a generator is used to harness the power of the wind and then a turbine is used to generate electricity.
- True
- False
A: False
If right: Great! In wind energy, a turbine is used to harness the power of the wind and then a generator is used to generate electricity.
If wrong: No, this is false. In wind energy, a turbine is used to harness the power of the wind and then a generator is used to generate electricity.

Q: Which of the following is not associated with geothermal energy?
- Photovoltaics create direct current electricity.
- In an EGS water is forcefully injected into wells to be heated and then gets pumped back out.
- A heatpump used in this type of system can provide central heating and air.
A: Photovoltaics create direct current electricity.
If right: That is great! Photovoltaics is associated with solar energy - not with geothermal energy.
If wrong: Incorrect. Photovoltaics is associated with solar energy - not with geothermal energy. Both the EGS and the geothermal heatpump are associated with geothermal energy.

Q: Which of the following is an advantage of wind energy?
- The process requires no fossil fuels to work.
- Methane is a natural byproduct of landfills.
- Extra energy from this source can be saved for use later.
A: The process requires no fossil fuels to work.
If right: Correct! The wind power process requires no fossil fuels.
If wrong: Incorrect. The wind power process requires no fossil fuels. (Methane gas would be used in a biofuel process. Extra wind cannot be stored for later use.)

Q: Only rivers and streams can be used when harnessing the power of water.
- True
- False
A: False
If right: Good. The power of the ocean tides can also be used.
If wrong: This is false. The power of the ocean tides can also be used.
