ESS Unit 7 Energy Sources & Energy Use in the U.S. & the World

Which of the following would NOT be considered a renewable energy source?

• Nuclear Energy

• Solar Power

• Wind Power

• Hydropower

Which of the following is considered a non-renewable energy source?

• Solar Power

• Coal

• Bioenergy

• Geothermal

Which of the following is NOT a benefit to using solar energy?

• It's plentiful & free

• The energy use itself generates little air pollution or greenhouse gas emissions

• Lots of energy is available from the sun

• The sun is not always available & its energy can be expensive & can be challenging to store.

Which of the following IS a drawback to wind power?

• It's plentiful & free

• The energy use itself generates little air pollution or greenhouse gas emissions

• The turbines require large amounts of land, can be considered noisy, & can often cause harm to birds.

• The turbines, once built, cause relatively low harm to the surrounding ecosystems.

Which of the following is NOT a drawback to hydropower?

• Water power can be generated day or night, year round

• Water power can vary with seasons & geographic location.

• Areas near man-made reservoirs & dams can be at flood risk.

• Damming rivers can cause major harm to river habitats & ecosystems.

Which of the following renewable energy sources does NOT use a turbine to generate electricity?

• Hydropower

• Wind Power

• Solar Power

• Geothermal

What is a benefit to using nuclear energy?

• Nuclear energy gives off large amounts of energy from a relatively small reaction & has low chemical air emissions.

• Nuclear energy can cause concern for human safety due to radioactivity.

• The waste from nuclear reactions can be harmful to living organisms & can be challenging to store.

• The risk of nuclear energy being used in non-peaceful ways can be of concern.

What is a benefit to geothermal energy?

• The power plants to harness geothermal energy can be expensive.

• Geothermal energy provides a constant flow of energy & there is an incredible amount available.

• Geothermal energy has geographic restrictions.

• The drilling for geothermal energy can cause environmental impacts & may cause risk for earthquakes.

Bioenergy comes from...

• municipal wastes (like trash!)

• crop residue & by-products of lumber & paper industries

• animal manure

• all of the above!

Which of the following is NOT a drawback to the use of Bioenergy?

• Using plant matter as energy can take decomposing plants away from the soil & cause soil infertility.

• Burning biomass or combusting biofuels still puts carbon emissions & air pollutants in the atmosphere.

• Using plant matter as energy disrupts carbon sinks.

• Bioenergy processes wastes & is relatively an inexpensive alternative energy source.
