Hydroelectric Energy

By Henry Charles

What is Hydroelectric Power?

Hydroelectric Energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed.

What is a dam?

A Dam is a barrier constructed to hold back water and raise its level, the resulting reservoir being used in the generation of electricity or as a water supply. It creates a type of energy that is called hydroelectric energy.

Disadvantages

Some of the disadvantages of having a dam is because they reduce water levels, block rivers, slows rivers down, alter water temperatures, timing of flow, fluctuate and all kinds of other things. But there are ways to solve those problems.

Advantages

There are many advantages of having a dam, or creating ways for hydroelectric power. One of the many advantages of having a dam for creating hydroelectric power is that you create more energy than usual. Another advantage of having a dam is that it reduces the amount of floods there are and it can control and prevent floods from happening. It also is a good way to create energy because there are many types of ways to create hydroelectric energy. Also there are other many ways to overcome the disadvantages. It might be bad in different ways but then, they have a clean energy source, they are renewable, Reliable and stable, and they don't cost a lot for the operating cost. Another advantage of hydroelectric power is that there is no fuel being burned and won't cause pollution.

Waterwheel

Waterwheels are another way of creating hydroelectricity. It creates energy by the free flowing water.
