The Benefits of Hydroelectric Energy Essay - 683 Words

Hydroelectric Energy What is Hydroelectric energy? Hydroelectric is a form of energy it is a renewable resource. Hydroelectricity is the most important and widely used renewable source of energy. Hydroelectric relies on water, which is clean and renewable energy source. Renewable energy comes from natural resources. Non-Renewable energy source includes coal, oil and natural gas. Water is renewable because water continually recycles itself. To harness energy from flowing water, the water must be controlled; a large reservoir is created, usually by damming a river to create an artificial lake or reservoir. Water is channeled through tunnels in the dam. The energy of water flowing through the dam causes the turbines to turn and make the†¦show more content†¦Its powers most of the building like homes, hospitals, schools, factories and etc. Hydroelectricity comes in a human cost. The huge damn that required for hydroelectric energy projects create a reservoir that floods an entire valley. Like homes, communities, and towns that may have to relocate as a dam construction begins. However, the projects to make a hydroelectric power generator has forced more than millions of people to relocate. Lifestyles were disputed. We don’t have to burn fuels to cause pollution†¦ pollution free. Hydroelectric developments don’t generate toxic by-products. With an average lifetime of 50 to 100 years, hydroelectricity developments are a long term. It can easily be upgraded to incorporate more recent technologies and have very low operating and maintenance cost. Dams are designed to last decades and so can so contribute to the generation of electricity for many years and decades. Hydroelectricity is the cheapest way to provide energy. Once a dam is constructed, electricity can be produced at a constant rate. Large dams can be useful for flood control. It’s a clean energy source. It does not produce green house gases. When a hydroelectricity water storage dam is built, the water can be used as d rinking water and also a recreational purpose such as fishing and boating. Dams saves and reserves water so that it is not wasted into oceans and seas.

The most common medium for using solar power is the use of solar panels. Through the use of solar panels people can use that harnessed electricity to power their houses, household appliances, their cars, even their towns and cities. Before the use of solar power people were using other sources of energy such as wind, and hydroelectric energy. The use of wind is a niceRead MoreHydro Electric Power1518 Words   |  7 PagesHydroelectric power: The Worlds Established Renewable Energy Resource For over a century, hydroelectric power has been used to generate electricity from falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Hydroelectric dams create height for the water to fall and provide storage. In general, the higher the dam, the more potential energy is available. Building up behind a high dam, water accumulates potential energy.

This is the concept of hydropower. Hydropower is using the energy of moving water to create power. This clean and renewable method of power generation is used all throughout the globe, and accounts for a small percentage of global electricityRead MoreHydropower Power : Hydroelectric Power744 Words   |  3 Pageselectricity comes from hydroelectric power or that seven percent of the United States’ electricity comes from hydroelectric power? Hydroelectric power is one of the more well-known renewable sources of energy. Around the world, there are roughly 160 countries that have hydropower. Hydroelectric power comes from water; generating electricity from water is a process similar to coal power plants, though much cleaner. There are some difficulties with using hydropower, but the benefits outweigh the negativeRead MoreThe Environmental Impacts Of Fossil Fuels1417 Words   |  6 Pages In recent decades, energy needs have seen unprecedented growth. Everyone is using more electricity. Currently, around 80% of the worlds’ energy consumption is supplied by fossil fuels, which include petroleum, coal, and natural gas (â€Å"Our Energy Use in Numbers†). Generally, these resources are cheap and readily available. They are arguably one of the most stable sources of energy and release high amounts of heat upon combustion, thus giving them a high calorific value (â€Å"Fossil Fuels - IER†). UnfortunatelyRead MoreAlternative Energy Sources For Renewable Energy1511 Words   |  7 PagesRenewable energy has become a widely popular topic in society. With the rapid depletion of fossil fuels, scientist are looking to natural and renewable resources to create a means to produce sustainable energy. There are many alternative energy sources that have proven useful in the past couple of years. Some of the alternative energy sources are not only more useful than others but have proven to be easier to attain and also prove to create a more substantial amount of energy. Today, the most widelyRead MoreAnalysis Of The Current Energy Productions And Distribution Systems876 Words   |  4 Pages(Jong H) Lee Historically, most of the current energy productions and distribution systems are centrally controlled regardless whether it is operated by government or private sectors. Not to mention most of the current government policies on those energy sectors are highly tailored of the centralized structure. Part of the reasons I can think of that is because the framework of the current energy model is largely focused on a big scale energy system. Although this is not necessarily mean bad,Read MoreHydroelectric Power Technology and its Effects on the Environment1174 Words   |  5 PagesFor centuries, scientists and energy experts from all over the world have been making efforts to look for alternative resources in order to solve human being’s energy crisis. Consequently, a great number of renewable energy source have been discovered, including solar power, nuclear power, wind-generated power and hydroelectric power. This essay aims at giving some basic knowledge on hydroelectric pow er technology with focuses on its impacts on environment. Firstly, a brief introduction of hydroelectricityRead MoreEssay about The Importance and Benefits of Hydroelectric Power1661 Words   |  7 PagesIntroduction: Hydroelectric power plant is one of the major power plants all over the world in order to create electricity. It is also one of the best renewable energy sources on the planet earth. In ranking, Canada is the third largest country to produce hydroelectricity power. The efficiency of this power source is 90% and this is very impressive as the percentage of efficiency is very high. Hydro power plants generate 24% of the world’s electricity.
