Renewable energy is energy that comes from a source that does not run out, no matter how much we use it. Non renewable energy is energy that comes from a source that is depleted as we use it.
Hydropower is an example of a renewable type of energy. This is because no matter how much we use hydropower, it will not run out.
Why is hydropower renewable? Hydropower is a type of energy source that comes from the earth’s water cycle. It can be generated by any type of water movement, from a natural waterfall to water that flows through a man made dam. Usually, hydropower comes in the form of hydroelectric energy. This is power that is generated by converting water in motion into electrical energy. Hydropower is also an eco friendly source of energy. Thus, as well as being highly sustainable (and thus a reliable option for the future for humans) it is a good option for the planet too.
