  • Renewable Energy And Alternative Energy

    Hydroelectricity is the utilization of flowing water to create electricity, usually through the use of a dam. Wind energy is classified as the use of wind to turn a turbine blade in order to produce electricity (Ellabban et al., 2014). Among all the renewable energies, hydroelectricity is the most widely used as it makes up 85% of the renewable energy market, has a capacity of 970 GW, and produced 3500 TWh of electricity in 2011. This is due mainly to the fact that hydroelectricity produces the cheapest electricity, because of its long history of use and low cost implementation. Wind energy is second among renewable energies with a total capacity of 238 GW. It is one of the fastest growing renewable energies as it grew by 28% each year from 2001-2011 (Pazheri et al., 2014). Wind and hydro energy are by far the most popular renewable energies, but the others have bright futures in the market as the share of renewable energy increases in the energy…

  • Hydrokinetic Energy Essay

    In human History the use of water has been used for a thousand years the starting point of creating energy using water has been in progress for centuries from theory to experimentation, and in real life possible applications. It gave birth in modern time as Hydroelectricity a term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. In engineer’s eye’s it is a debatable energy source due to…

  • Do Companies Use Renewable Energy?

    way into homes across the area of the wind turbine. These turbines usually take up a large portion of land or sea, but it is not uncommon for farmers with a lot of land to have one. Hydroelectric Dams Hydroelectricity is obtained most efficiently through the use of a dam. These dams are usually built on rivers or lakes where massive amounts of water can flow through them. The way they work is when a control gate is open the water flows through a channel that spins a turbine that is connected to…

  • The Benefits Of Solar Energy In Cameroon

    By doing this, the cost of providing hydroelectricity for individuals in Cameroon - who have no energy - will be transferred to the non-profit organizations. The government will then have residents with better healthcare access, eco-friendly energy, and a reduced carbon dioxide footprint. By granting this opportunity to the government of Cameroon, through non-profit organizations, we also establish a reliable relationship with them. In the future, if or when the country of Cameroon decides to…

  • Hoover Dam Advantages And Disadvantages

    produced for an average of 0.85 cents per kilowatt-hour (kwh). This is about 50% the cost of nuclear, 40% the cost of fossil fuel, and 25% the cost of using natural gas,”. If one takes in to consideration that the Hoover Dam produces averagely 4.2 billion kilowatt hours, it acquires a lot of money. More than that though, although it is pricey to construct a hydropower plant, it pays for itself in the long run. Another draw back from having a hydropower plant is “ "Dams hold back silt, debris,…

  • Why Do People Use Renewable Energy?

    until the sun is gone. In addition, another form of energy source that produces electricity is water. A renewable energy source that uses the water is hydro-power. Hydro-power means using water to make electricity. Water is the most well-known renewable source in the U.S. today. Hydroelectric power plants use dams or rivers to hold water. Water flows through a little gate that runs through a spinning turbine, activating a generator that accounts for the electricity. A hydroelectric power plant…

  • The Benefits Of Renewable Clean Energy

    In today’s world our growing need for energy has created more demand for more resources. The population and technology influences the need for energy. This energy is not just in our lights and heat but in our transportation needs as well as other life systems. Currently coal, gas, and oils power most of our needs while renewable energy is following behind and being used in some portions. The need to bring renewable energies into focus is one in which our business and communities can do.…

  • The Potenning Factor In The Different Forms Of Power Water And Hydroelectric Energy

    The binding factor in nearly all kinds of power plants is how the power is actually produced: something heats water, turning it into steam, which then turns a turbine that generates electricity. The differentiating factor in the differents forms of power plants is how that water is heated. Nuclear plants fancy splitting atoms, coal plants burn coal, and geothermal plants skip the middle man, let Earth do the heating, and simply reap the benefits. Below the surface of Earth is a layer of rock so…
