Hydroelectric Energy: The Benefits
In our quest for becoming a greener Earth, one of the best solutions is the continued usage and utilization of hydroelectric energy. Hydroelectric energy is created by utilizing the gravitational force of falling or flowing water. This process is quite reminiscent of the way that wind energy is created. Most people dont know, but roughly 7% of the utilized power in the United States is created using hydroelectric energy.
One of the major ways of utilizing hydroelectric energy is through dams. By damming up water flow behind a large concrete wall, it is possible to generate an enormous amount of potential energy. Once the water is released, it flows through a turbine and an electric current is created. This electric current can be used to power both businesses and homes.
This rather elegant method of creating energy without drilling for coal or burning fossil fuels enables us to benefit from a natural resource to create hydroelectric energy. This energy source not only does not pollute the Earths atmosphere but also reduces green house gasses, and consequently, the threat of global warming. Better yet, this energy is virtually limitless, as the water from streams and rivers is provided by rain fall and is naturally replenished.
Obviously, hydroelectric energy can only be used in countries where such water sources are available. However, fortunately this is the case in many countries. An additional advantage of this energy source is that it is relatively cheap; after the hydroelectric power plants are built, they are easy to operate and do not require a lot of expenses. Better yet, this is just the beginning: the technology continues to mature, so it is expected to become cheaper and more widely spread.
Whether the source of energy is wind, water, fuel, coal or the sun, the benefits we gain are unlimited as electricity can be harnessed in so many ways. That being said, obtaining electricity using water is one of the best methods of all. By continuing research and development on this energy source, we guarantee that in the future it will play a larger part, and will be used to power everything from home appliances, to televisions, to factories. It is even possible to store this energy and later use it in a vehicle, and this reduces our dependency on fuel.
