The use of hydroelectric dams have been in place since the early 1960’s. As far as the environment is concerned, hydroelectric dams are an excellent choice. They don’t burn fossil fuels so they aren’t polluting the air. They also aren’t consuming valuable natural resources that we have in limited supply on Earth.
Yet they aren’t always reliable though and that is a major concern in society. They have been know to fail at times and resulted in hundreds of thousands of people being killed. There is also plenty of concern that these types of dams will be compromised by terrorists as a way to attack our country. After the 09/11/01 attacks we can’t be too careful about what could take place.
There are plenty of benefits from hydroelectric dams though. They provide plenty of power which we all rely on for personal use and for businesses to be able to continue production. Approximately ¼ of all the electricity in the world is the result of hydroelectric dams. That means millions of people rely on it each day for their supply of power. It is considered to be a breakthrough in the making of renewable energy.
With a hydroelectric dam water can be controlled to help prevent flooding. This means if too much water is coming in it can be released to other areas so that things in the way of water aren’t destroyed. If there isn’t enough water it can be turned the other way so that there won’t be a shortage.
Huge generators are in place along the hydroelectric dams in order for the electricity to be produced. Thousands of megawatts of power are produced each day from these facilities. While it does cost millions of dollars to make them, they are very valuable to us. The more we can preserve our natural resources the better off the world will be for future generations.
There are approximately 2,000 hydroelectric dams found around the world. One of the most well known hydroelectric dams in the world is the Hoover Dam. It is a very popular tourist attraction along the border of Nevada and Arizona. It was built in the 1930’s and for a decade it was the largest hydroelectric dam in the world. Today that top honor belongs to the Grand Coulee Dam.
