Advantages of Hydroelectric Energy

By Sophia


There are many advantages of using hydroelectric power, the power of falling water. It is a clean source that doesn't have much of an impact on the environment. Water is a renewable source that never runs out and the water is saved when passing through the dam. Although the U.S. doesn't use it that much, there are many other countries that use it often. The picture on the right shows how much hydroelectric power is used in Canada compared to all the other sources of energy. More than half its energy is run by Hydroelectric power! That's how useful it is!

Hydroelectric power produces a useful amount of energy for electricity in homes and small processing machines. The picture below shows an example of what a dam looks like.

After the dam is built on a river, this useful source of energy is very inexpensive to maintain (only an average of 0.7 cents per kilowatt-hour!). That is one-third the cost of fossil fuels and one-sixth the cost of natural gas! The graph below shows the price to run hydroelectric power compared to all the other forms of energy. It is the cheapest energy source out there!


Look at how little Hydroelectric energy costs to maintain compared to the others!

The dams can also store rainwater and river water, so in case there's a drought, there will still be a supply of water. It controls flooding in rivers and in case of a problem, dams can be shut down instantly while thermal plants can take hours and nuclear plants can take days to shut down. The power plants and dams have very few break downs and when they do break they are easy and inexpensive to repair. Hydroelectric plants produce useful levels of energy, and because of the cost and how environmentally friendly it is, hydroelectric energy is a great source of energy to use.
