Answer :

Final answer:

Hydropower is a clean and renewable energy source, along with solar, geothermal, and wind power, which are environmentally friendly and do not produce pollutants or contribute to climate change.


Explanation:

Hydropower is considered a 'clean' energy source because it relies on water to spin turbines and create electricity without directly producing pollutants. It is also renewable as the power source is regenerated. Hydropower provides 35% of the United States' renewable energy consumption.

Other clean energy sources include solar, geothermal, and wind power. These sources do not contribute to climate change or local air pollution as they do not involve combustion of fuels.

Renewable energy sources like hydropower, wind, solar, geothermal, and biofuels are replenishable and generate electricity efficiently, making them environmentally friendly options.
