Hydroelectric Energy Alternative To Fossil Fuels

824 words - 4 pages

  Earth is fill with abundant resources that us, humans, use to heat our homes, make the cars move, produce electricities and many other activities that we do. We mainly use fossil fuels as the main energy sources for these jobs, however with centuries of digging for fossil fuels and use them up, their supplies is running low because they are a non-renewable resource which means you will use them all up before they can be replenish. With their supplies running low, we need to find an alternative resources to replace fossil fuels for electricities and for the fuel for our transportations. Hydroelectric energy is the perfect choice of replacement.
  Hydroelectric energy is an alternative energy source that can be use to power houses. Hydroelectric energy came from a water dam or a hydroelectric power plant in which water is channeled through tunnels in the dam and the power of the water causes turbines inside the dam to turn. Then the turbines make generators inside the power plant to move and the generators produce electricity which is send through a system of transmissions lines that all major power sources are connected to called the grid, for everyone in the nation to use. Just like all energies, hydroelectric energy is not all perfect, it has both advantages and disadvantages over the environment and the economic. The first advantage of hydroelectric energy is that the water which is being used to run the power plant is provided free by nature which means it is a clean resource, and that leads to less pollution, and the reduction of greenhouse gas emissions that contributes to global warming. The second advantage of hydroelectric energy is that the cost of hydroelectric energy is cheap with a daily cost of only 12 cents, with a yearly cost of only $44.11 to produce them. The cost of hydroelectric energy for an individual person is only 8 cents a day and the cost of hydroelectric energy for a home is 24 cents per days for a typical 3 member family. The third advantage of hydroelectric energy is the dam or the hydro-power plant is reliable and strong for centuries, and this means relatively low operations and maintenance costs on the dam. The fourth advantage of hydroelectric energy is that it is a renewable resource which means we will run out of this resource. The fifth advantage of hydroelectric energy is that hydroelectric energy is very efficient. Modern hydro-turbines can convert as much as 90% of the available energy...

The ending amount of fossil fuels are in sight, therefore the prices continue to climb without bound (Nelder). This is where the United States must find alternative to fossil fuels. However, even when converting to renewable energy, the cons to this conversion still happen to show up. Just because it’s

Energy and the Environment: Fossil Fuels

498 words - 2 pages Energy and the Environment: Fossil Fuels Fossil Fuels are one of the most important things on this planet to the human race. Without fossil fuels we wouldn't have today's current means of transportation, we would have less heating for the general population, energy uses would be more expensive, and overall the economy and the world would not be able to sustain themselves. Even still, the fact that fossil fuels are on this planet will never

Is Biodiesel a Viable Alternative To Diesel From Fossil Fuels For Trucks And Buses?

1029 words - 4 pages of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as

Assess The Potential Of Three Sources Of Renewable Energy As Alternatives To Using Fossil Fuels

1793 words - 7 pages After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution, cheap fossil fuels then became the main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more

Replacement of Fossil Fuels with Nuclear Energy for Electricity

1282 words - 5 pages Replacement of Fossil Fuels with Nuclear Energy for Electricity ABSTRACT Our nation is on the brink of an energy crisis and alternative means to produce electricity must be found. Fossil fuel resources are declining sharply and nuclear energy is the leading form of replacement. Our research shows that the advantages to this new energy source are extraordinary and that there are many ways to minimize its negative aspects. Due to the
