Hydroelectric EnergyEarth ScienceBy Austin EdwardsHydroelectric energy was one of the first sources of energy used. It is used by the powerful flow of water currents. The first dam ever built for the exploitation of hydroelectric energy was built on September 30, 1882 in Appleton Wisconsin. After that dam, over 2,044 billion kilowatt hours are produced every day in all parts of the world. Initially not very popular, its production has steadily increased over the years. The reason for its growing number is due to its reliability. Why is it so reliable? There is always water constantly flowing everywhere in the world. Dams are built in areas where water moves quickly, such as rivers and streams. It is so reliable because no matter what happens with the weather or anywhere on earth, unless the river or stream runs dry, the water will always be in constant flow. Some days the flow may be faster than others producing more energy, even though it wouldn't produce as much energy, a slow and steady pace will still produce a decent amount of energy throughout the day. How do these dams work? There are many steps involved in the process of producing this energy, although the first step of production is that the water must enter a series of huge pipes and collide with the turbine blades which causes the blades to rotate. . As these blades spin, outside is a long stick, which is connected to a generator, filled with magnets where all the electrons are produced. After all these steps, all the electrons produced are pushed through power lines to power homes, businesses, and schools in the area. After all these steps have been completed, the water used to push these turbines is now... half paper... that's about 80,000 people evacuated. So a single dam can cause thousands of people to lose their homes and properties. Finding a place to fit a giant dam is also a difficult process, even if you are able to remove people's homes, the dam must be placed in the right spot to have maximum production. Plus, more things in the way means more things to remove from the area, resulting in more manpower, more equipment, and more labor, all costing thousands of dollars to add to your budget. All in all, hydroelectric energy is a very useful and powerful tool that the world has at its disposal. With all this data and debate there are more pros than cons and with the pollution problem, this solution is a must. It is correct to say that the world should use as much hydroelectric energy as possible to keep the earth clean and healthy and at the same time be able to produce the electricity needed by humans in everyday life..
