The correct answer is **B. All use generators to produce electrical current.**
Wind turbines, hydroelectric dams, and ethanol plants all involve processes that ultimately include generators to convert mechanical energy or chemical energy into electrical energy. However, it's important to note that not all produce electrical current without pollution, nor do they all convert gravitational potential energy or thermal energy directly into electricity.
