Tidal energy cannot become a significant resource worldwide because
- the accompanying tidal waves cause too much environmental destruction.
- the equipment required to harness this energy is not yet.
- few areas have large enough differences in water level between high and low tides to make power generation feasible.
- sand damages the equipment.
- tidal energy can become a significant resource worldwide.
All of the following have potential to produce geothermal energy except
- hot springs.
- deep ocean hydrothermal vents.
Where does the energy needed to run a geothermal plant in California originate?
- subsurface coal mining

Energy efficiency is defined as
- energy that escapes in an unusable form.
- energy in bonds broken (minus) energy in bonds formed.
- using fossil fuels instead of renewable alternative energy.
- using less energy to accomplish a given task, by using new technology, for example.

Electric meters can run backward for homeowners participating in net metering. What does this mean?
- homeowners receive meter credit for excess energy they generate and supply to the utility’s power grid
- the up front costs for installing renewable energy is recovered by rewinding the home’s electric meter
- if a homeowner uses less energy in one month than the previous month, then the difference is subtracted from the electric meter
- homeowners who voluntarily cut back on air conditioning use are granted an electric credit
- a radio controlled electric meter for remote monitoring allows the utility company to stop the meter during peak demand periods
