Which statement about wind energy is true?

• A. It uses wind to generate electricity via wind turbines.
• B. It uses water flow to spin turbines.
• C. It absorbs wind to desalinate water.
• D. It uses fossil fuels to power turbines.

Answer: (A)

Wind energy captures the kinetic energy of moving air and converts it into electrical energy with wind turbines. When wind blows, it pushes the turbine blades, causing the rotor to turn. That rotational motion drives a generator, which converts mechanical energy into electricity that can be fed into the power grid. Because wind is renewable and the turbine itself doesn’t burn fuel during operation, the electricity produced has no fuel-related emissions at the point of use. The other statements point to different concepts: using water flow to spin turbines describes hydroelectric power; using wind to desalinate water isn’t how wind energy is described as the energy conversion; and using fossil fuels to power turbines would produce energy without relying on wind, which is contrary to wind energy.
