Unit 10 Energy Review

What characteristic do all renewable resources share?

• Produced by waste products of animals

• Easily accessible and affordable

• Form underground from organism remains

• Replaced in a reasonably short time period

This renewable resource uses photovoltaic (PV) cells.

• Wind

• Solar

• Natural Gas

• Biomass

Splits uranium atoms to produce tremendous amount of heat.

• Hydropower (dam)

• Solar Energy

• Natural Gas

• Nuclear Energy

Which is NOT an example of biomass?

• 
  wood

• manure

• crop leftovers (the part of the plant that isn't consumed)

• 
  petroleum

Which of these FOSSIL FUELS produces the least carbon emissions?

• coal

• crude oil

• natural gas

• petroleum

All of the following would increase carbon emissions EXCEPT

• replace coal power plants with solar energy

• use natural gas instead of hydroelectric

• reduce the number of nuclear power plants

• increase the use of biomass

The main advantage to using natural gas over coal or crude oil is that

• it is more abundant and cheaper to harvest/mine

• it is the most accessible energy source

• it burns cleaner and has less air pollutants

• it is better for the economy

Most oil in the US is used for what?

• Power Plants

• Transportation

• Cooking

• Supplements for human and animal health

Which energy production method produces the MOST air pollution?

• Natural gas

• Nuclear

• Coal

• Solar

What is the major drawback or risk of nuclear energy production?

• It creates air pollution.

• It creates radioactive waste.

• It creates water pollution.

• It destroys ecosystems.
