Fossil fuels have been a means of obtaining energy for decades. In 2006, humankind uses one billion barrels of fossil fuels per year and in 2012, it multiplies up to 30 billion barrels per year. Chris Nelder, an energy futurist and analyst, says, “[Soon] You will never see cheap gasoline again. You will probably never see cheap energy again (Nelder).” Indeed, scientists predict that we are extremely close to the peak oil production, a state of extracting the maximum oil each year ("The Peak Oil Theory Explained"). After the occurrence, oil output will drastically deplete while the price increases. Therefore, since energy is essential in life, we are in need of alternative sources. This essay will be explaining the solution, which is hydroelectricity: what it is, how it works and the implications it brings.
Hydro is derived from Greek origins meaning water. In other words, hydroelectricity is a form of energy generated by converting water into electricity. Hydroelectricity is considered a type of renewable energy due to its use of water. There is an unlimited supply of water in the world because of its continued and unending cycle: rain, evaporation and condensation. Ancient Romans were recorded as the first to develop the turbine method, which plays a major role in hydroelectric power plants.
Hydroelectricity’s driving force is gravity since it makes the water run from higher grounds to lower levels ("Hydropower's Unexpected Side Effects"). The falling of water creates the
Water turbines are near the oldest ways to run power without using fossil fuels. The new age had turned these into hydro turbines that generally reside in dams. These machines take similar shape to wind turbines. Hidden in the base of a dam, there is a very large turbine that, in a simple explanation, when water runs through it spins. With the energy used by the spinning turbo it is turned into different power sources that are stored into power cells. Way back in time, this idea was used in power mills. Those old spinning wheels on the side of houses that rotate with water pressure. The first power plant was constructed in 1879 at Niagara Falls, Canada. In the United States the first plant was in 1882 in Wisconsin. These extravagant machines seemed marvelous, but that is no longer the outcome. The current age hydroelectricity dams are currently being shut down for harmful aspects triggered from the giant production. Causing an environmental failure to marine life and habitats all around. The possible outcomes are: changing the oxygen levels in the water that cause organisms to perish; fluctuating water levels that cause different
Furthermore, generating hydroelectricity does not produce any kinds of greenhouse gases or smog emissions. Finding the balance between an efficient energy source that does not produce any greenhouse gases are crucial, especially in this day and time, where climate change is prominently becoming a large issue not just in Canada but all over the world. Between 1990 and 2013 Canada’s increase in emissions were caused by fossil fuels. Fortunately, there was a slight reduction from 2005 to 2013 and that was from the public electricity sector, for example, by using hydroelectric stations. If canada increased the percentage in which the hydroelectric stations supplied energy to, Canada could potentially cut down on greenhouse gas emissions and smog.
to get clean energy for use of cars planes and other things that we use everyday.
Hydropower is a renewable resource that is clean, affordable and durable. This resource is clean due to the way you gather the energy from it. hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller piece called a turbine, which then turns a metal shaft in an electric generator (the motor that produces electricity). A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric
The Hoover Dam, located on the common state boundary of Arizona and Nevada and operated and maintained by the U.S. Department of the Interior 's Bureau of Reclamation, is one of the largest hydropower projects in the United States. Completed in 1936, the primary purpose of the Hoover Dam is to control the waters of the Colorado River during flood seasons and to eliminate the annual threat of flood damage in order to protect the fertile regions below. The dam also provides a stable supply of irrigation water and various domestic use supplies for southern California and southwest and central Arizona by storing the annual Colorado River runoff. Finally, the Hoover Dam produces hydroelectric power at an average generation rate of 4.5 million kilowatt hours per year in order to serve nearly 8 million California, Arizona and Nevada residents. This paper will discuss a broad overview of hydroelectricity, the construction of the Hoover Dam and Hoover Powerplant, the specifics of the electricity produced at the Hoover Powerplant, the consumption and usage of that hydropower and the impacts of the recent regional drought conditions to hydropower production.
In this paper I will be discussing the renewable technology Hydropower and the pros and cons of it. I will be using three separate articles from GREENR focusing on hydropower as a whole and some of the possible downsides of this technology in addition to the very noticeable positive effects from hydropower. The three articles mentioned are "Building BRIC: Carrieann Stocks takes a look at recent developments in hydropower across Brazil, Russia, India and China." (International Water Power & Dam Construction) (Jan. 2015), "Electricity Production from Hydroelectric Sources, Top Ten Countries, 2003/4." (Global Reference on the Environment, Energy, and Natural Resources Online Collection), and "Green streak." (Earth Island Journal) (Jun. 22, 2015). I will be discussing the possible reasoning behind some people not wanting to focus on this possibly very beneficial alternative and try to explain why “If Hydropower is available why don’t we use it?” Keywords: dams, turbine, hydroelectric, renewable resource, nonrenewable resource
Everything runs with electricity and it is produced by dams. Hydro-electric dams are very important nowadays as they supply a lot electricity. Society believes that hydro- electric dams are not very useful in the creation of electricity. Hydro-electricity is electricity which is produced by water. Canada is ranked second out of the world in the production of hydro-electricity and the hydro-electric dams produce 60% of Canada's total energy. There are about 933 hydro-electricity dams in Canada. Quebec has the most of these dams, there are 333 hydro-electric dams in Quebec. Hydro-electric dams are not an environmentally responsible form of generating energy. The hydro electric dams will cause droughts and floods, increase global warming, and
These sources of energy have a great upside, but right now are incredibly inefficient compared with fossil fuels because of the lack of funding and worldly push (2009). If there isn’t a bigger investment in these alternative energies, fossil fuels are going to maintain their stranglehold on all the economies of the world (Lomborg, 2009).
In conditions when both technologies and our needs require more and more energy, it is impossible to count only on natural resources and to think that their reserves are unlimited. This is not true. We have learned to receive electricity from irreplaceable resources – oil, gas, also from replenished - water, wind, sun. But the energy of the sun or wind is not enough for today’s rythm of our civilization. And hydroelectric and thermal power plants are not as clean and economical for the modern rhythm
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
To elaborate, dam is one of major parts to discuss about firstly. The process of a dam is to store water by creating a large reservoir. This reservoir could be a lake or any other natural water source. The dam is most likely located at higher level ground than the turbines of the power plant. The dam contains gates at its bottom to control the water flow. As the gates open, the water stored in the dam flows downstream as gravity pulls everything down or towards the earth’s surface. The falling water goes through a pipeline called penstock. This pipeline leads to the turbines in the hydroelectric power plant. Much water flow in the pipeline means greater pressure from water. As the water comes down the pipeline, it hits the blades of the turbines and makes it rotate simultaneously. The speed of the rotational blades depends on the speed of the water flow. As a result, much pressure of water flow will rotate the blades with a higher force and vice versa. Francis Turbine is the turbine that is most common for building hydroelectric power plant. This type of turbine looks like a big
The main focus of this chapter is hydroelectric power provided by the Columbia River, and the subsequent switch to nuclear power. The development of hydroelectric power requires the building of many dams, which at the time was commissioned by the BPA also known as the Bonneville Power Administration. The importance of the building of such dams goes far beyond the power they produced. An important attitude White is trying to give off is that by centralizing power under an administration, the importance of the people doing the work is diminished. Another point that he emphasizes is that the river never failed he states, “we have not killed the river; we have disappointed ourselves” (p.60). This idea will be discussed further in the paper. All
With American population expected to increase by approximately fifty percent over the next fifty years, some sort of energy reform is needed (Lehrman 2). The most commonly proposed idea is for America to stop relying so heavily on fossil fuels, and to turn its focus onto renewable sources of energy, such as solar power and hydroelectricity (Energy Information Administration). If the United States could realize the benefits of renewable energy, then much of the world’s energy problems could be solved.
Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.
The principal component of a hydropower plant is a dam, which holds back the water, creating a reservoir. The water in the reservoir has potential energy, which turns into kinetic energy as it flows through
