Hydroelectric Energy
Hydroelectric energy is made by flowing water. / Most hydroelectric power plants are located on dams, / which block the river and create an artificial lake. / A controlled amount of water is forced through tunnels in the dam to produce electricity. /
Hydroelectric energy has some advantages. / First, it’s fairly inexpensive to produce. / Dams don’t need to be complex, / and the resources to build them are not difficult to obtain. / Second, its source is available to many people as rivers flow all over the world. / Third, it’s fairly reliable for the flow doesn’t depend on the weather but the control by engineers. /
However, it has certain disadvantages too. / Hydroelectric power plants are damaging to the environment. / The lake created behind the dam drowns the original river habitat deep underwater. / Besides, these plants don’t work for a very long time, / because the dirt from a river bed builds up behind the dam and slows the flow of water. /
解析
水电能源
水电能源是通过流动的水制造的。水力发电站大多位于水坝上,这些水坝阻截河流,制造出一个人工湖。人们通过控制一定量的水从水坝内的渠道流过来发电。
水电能源有若干优势。首先,它的生产成本还算低廉。水坝不需要很复杂,而建造它们的资源也不会太难获取。其二,它的来源可以为多数人所得,因为全世界都有河流流过。其三,它较为可靠,因为水流不需要依靠天气而是受工程师的控制。
