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.
Additionally, wherever it can be used - which is quite a lot of places, since many countries have rivers - this is relatively a cheap source of energy. Once hydroelectric power plants are built their maintenance is not expensive nor are they hard to operate. Furthermore, this is just the beginning: it is estimated this technology will continue to mature, thus, the costs and benefits would just increase.
No matter where the energy comes from: sun, wind, water, fuel or coal, we clearly are dependent on it, as it is used in a great variety of ways. Thus, using water to obtain electricity is one of the best alternatives for the reasons we mentioned. Not only it can be used to power home appliances and factories, but it could also be used to store energy which is later reused in vehicles. In conclusion: it is expected that as this technology continues to mature, it will become cheaper and more widespread.
