Recently I am writing a paper about hydropower. This is an assignment for me which is given by my instructor in PHYS 1001W. To tell you the truth, I have no idea about hydropower until I find this page in internet. This is a website from National Geographic, which is my favorite journal in US. In this website, it tells us the definitions of hydropower, the history of hydropower, the usage of hydropower, and its impact on environment.
It is known to all, hydropower is an integral part of the overall renewable energy. Nowadays, with the increasing serious concerns about shortage of fossil energy and greenhouse gas emissions around the world. Hydropower has become the energy that could not only be cycle, but also be environment friendly. As hydropower is generated electricity from water, we could use this electricity with a very low price. It could also help to irrigate fields and control the flood. So it seems that the hydropower really takes an important role in our lives. However, it still has some bad influences. For example, while building dams for hydropower, it may destroy some natural scenery and habitats. What’s more, it may cause geological disasters in the future. That’s why we should treat it in a more impartial way.
Above all, hydropower could be a gift for us which is presented by the sun. Once we make full use of it, we should have more good feedback in the future.
