Explanation:

1. Coal, natural gas, nuclear, and some solar power plants all use thermal energy to drive the turbine generator. Coal and natural gas burn fuel to produce thermal energy, nuclear fission releases thermal energy, and some solar power plants (like concentrated solar power) use thermal energy. Cooling towers are not used by all (e.g., some solar), nuclear and solar don't burn fuel, and nuclear doesn't emit CO₂.
2. Canada has long been the largest provider of imported oil to the U.S. due to its proximity, large oil sands reserves, and established trade relationships.
3. Hydropower has historically generated the largest percentage of renewable electricity in the U.S. due to its large - scale infrastructure like dams.
4. Nitrogen (\(N_2\)) is not a greenhouse gas. Water vapor (\(H_2O\)), carbon dioxide (\(CO_2\)), and methane (\(CH_4\)) are well - known greenhouse gases.
5. Most thermal power plants have an efficiency of roughly one - third (\(1/3\)). Energy is lost in various forms like heat during the conversion process.

Answer:

1. D. all use thermal energy to drive the turbine generator
2. D. Canada
3. C. hydropower
4. D. \(N_2\) (nitrogen)
5. A. one - third (1/3)
