Which energy source is derived from water and turbines?

• A. Geothermal energy
• B. Hydroelectric energy
• C. Coal energy
• D. Wind energy

Answer: (B)

Hydroelectric energy is derived from the movement of water, typically from rivers or dams, that drives turbines to generate electricity. In this process, the kinetic energy from flowing or falling water is converted into mechanical energy by the turbines, which are then transformed into electrical energy. This method harnesses a renewable source, as water cycles through the environment continually. In contrast, geothermal energy originates from heat stored in the Earth, typically accessed through steam wells or hot springs, while coal energy is obtained from burning fossilized carbon sources. Wind energy is generated by harnessing the wind's kinetic energy using wind turbines. Each of these other options represents a different source of energy that does not rely on the direct conversion of water flow into electrical power like hydroelectric energy does.
