Understanding Renewable Energy: Sources and Impact

Hydropower is generated by harnessing the energy from flowing water, commonly from rivers or dams. Coal, solar, and wind are also sources of energy, but they are not specifically related to hydropower.

Wind energy is generated by harnessing the movement of air to produce electricity. The other options listed are different sources of energy generation.

The Sun is the primary source of energy on Earth, providing sunlight that enables photosynthesis and powers various ecological processes.

Geothermal energy is derived from the heat of the Earth's core, whereas solar energy comes from the sun, wind energy comes from moving air currents, and hydroelectric energy is generated from flowing water.

Biomass refers to organic materials that can be used as a source of energy, such as wood, crops, or waste. Solar, wind, and hydroelectric are also renewable energy sources, but they do not fall under the category of biomass.
