Which comparison between natural gas and coal-fired electricity is best supported by the material?
- A
Natural gas has no greenhouse-gas impacts because it burns cleanly.
- B
Natural gas generally emits less carbon dioxide per unit of electricity than coal, but methane leakage is a concern.
- C
Natural gas is renewable because methane forms naturally.

Which statement best explains why electricity is classified as a secondary energy source rather than as renewable or nonrenewable itself?
- A
Electricity is always a renewable primary energy source.
- B
Electricity is a secondary energy source whose impacts depend largely on how it is generated.
- C
Electricity is always a nonrenewable resource because power plants require fuel.
- D
Electricity is a useful energy service rather than an energy carrier.

A wind farm is rated at 200 megawatts but produces less electricity than that rating over a year. Which statement correctly distinguishes its capacity from its generation?
- A
Capacity measures electricity actually produced over a year, while generation measures maximum possible output.
- B
Capacity and generation are two names for the same measurement.
- C
Capacity is maximum instantaneous power output, while generation is electricity actually produced over time.
- D
Capacity measures transmission losses, while generation measures electricity delivered to consumers.
