The bulk of the electric energy produced in the US is generated using what method?

• A. Hydro
• B. Nuclear
• C. Wind & Solar
• D. Fossil-Fuel

Answer: (D)

The main idea is that electricity in the U.S. is still produced mostly by burning fossil fuels. Fossil-fuel-fired plants, especially natural gas and coal, provide the largest share of power because they have high energy density, a long-standing, well-developed infrastructure, and the ability to run continuously to meet demand. Nuclear contributes a steady portion, but it’s not as large as the combined fossil-fuel total. Hydroelectric power and the growing wind and solar capacity add to the mix, but they have not yet surpassed the amount produced by fossil fuels. So, among the options, fossil-fuel generation best explains why the bulk of electricity comes from that method.
