In the 1930s, windmills were widely used to generate electricity on most farms in the United States. Which kind of energy resource is used in windmills?

A. recyclable energy
B. nonrenewable energy
C. renewable energy
D. potential energy

The answer for that question is C: renewable energy

The kind of energy resource used in windmills is renewable energy. To determine the answer, we can start by understanding what windmills are. Windmills are devices that convert the kinetic energy of the wind into mechanical energy, which is then used to generate electricity. Since wind is an abundant and naturally occurring resource, it is considered renewable. Renewable energy refers to energy sources that can be replenished or regenerated naturally, such as solar, wind, hydro, and geothermal energy. Windmills harness the power of the wind, which can be constantly replenished, making it a renewable energy resource. Therefore, the correct answer is C. renewable energy.
