Global warming is slowly heating up the Earth, and fossil fuels are only making the situation worse.
That's why we should switch to hydropower for our energy needs.
Hydroelectricity is a clean, renewable source of energy that emits few pollutants and doesn’t damage the environment.
In fact, according to the Department of Energy, hydroelectricity utilizes the power of flowing water to turn a turbine, and generate electricity.
The Department of Energy says that hydropower can provide back-up power, as in certain kinds of hydropower, such as impoundment hydropower, water is dammed, and creates a large reservoir. These can be opened and closed, depending on the energy required at any certain time.
Also, as hydropower can generate power to the grid immediately, they can provide back-up power during power outages.
In fact, the Department of Energy explains that hydroelectric power relies on the water cycle, which is driven by the sun. The sun rises and sets every day, making hydropower very reliable.
Finally, Hydropower is very reliable.
However, a dam that creates a reservoir may obstruct fish migration. They can also change natural water temperatures, water chemistry, river flow characteristics, and silt loads.
But you forgot that the US Department of Energy has sponsored research that could reduce fish deaths to lower than 2%, in comparison to the current 5% kill rate.
We should stop looking to fossil fuels; hydroelectricity is what will truly carry us through the future.
