    about hydroelectricity. One can see this shift in thinking in a 2012 report released by the United States Energy Department which details how 90% of all dams in the US are not producing electricity with 63% of those dams suitable for hydroelectric energy production (Hydropower resource assessment and characterization). A critic of the hydroelectric retrofitting strategy might point out that in the same report it details how these dams have the capabilities to produce only fifteen percent more hydroelectric power, and how this is a very underwhelming statistic considering hydroelectric power only produces six percent of the total energy produced in America. This is a valid point, but the energy creation isn’t the most promising quality about hydroelectric energy generation (What is U.S. electricity generation by energy source). The most promising quality hydropower possesses is the reduction of curtailments of other less predictable energies, such as solar and wind power, through a process called pumped storage. Pumped storage saves energy from peak production hours by pumping water up the dam in order to be able to recapture the pumped water’s energy in times of low energy production from solar or wind sources. Granted, not all dams have the capability to produce pumped storage electricity and even those that do destroy the ecology of a river system by providing variable water lines. But, as of right now 97% of all utility grade electricity storage is stored in pumped water…

    With fossil fuels causing harm to our environment, it is important to search for alternatives that will benefit our earth. Alternative energy is energy that is widely available and environment friendly. These alternative energy sources do not consume fossil fuels; instead they are nuclear, solar, wind or hydroelectrically powered. These energy forms are more environmentally friendly because they cause little or no pollution. It is important to know the different types of alternative 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…

    Energy is the refined power created when one burns resources or generates electrical charges from raw powers of nature. Humans use energy to power their homes, businesses, or other establishments and their technologies. The people around the world use massive amounts of energy generated by using natural resources. Most of the energy they use originates from burning natural resources like coal, oil, and natural gas, but the resource burning is creating dangerous gases like carbon dioxide. The…

    Impacts Of Hydropower

    • 1039 Words
    • 5 Pages

    Hydropower is power that is generated from a dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United…

    At a whopping 15 million degrees C, the 4.6 billion year old sun is responsible for Earth 's climate and weather. We rely so much on the sun without even realizing it—it 's the reason we even exist. Dennis Cui from Young Scientists Journal says that "The Sun has been, and always will be, the Earth 's largest energy reservoir-it powers every living system, from plant photosynthesis to every node of the food web. Humans, like all other organisms, depend on sunlight" (6-10). Why not use the sun…

    One of the ways that electricity is generated for use in our everyday lives is through hydroelectric power generation. This process involves using natural waterfalls or building dams to utilize the falling water to turn turbines. The reason why this process is possible is because of motion. Motion is the conversion of movement into useable energy, in this case to power of the turbines and generate electricity. Motion is affected by displacement (the final difference in position), instantaneous…

    The Great Transition: Shifting from Fossil Fuels to Solar and Nuclear Energy is a book that presents a definitively anti-fossil fuels stance on renewable energy written by Lester Brown, a lauded environmental scientist with more than 50 years of experience in the field of renewable energy who is certainly qualified to write about the topic. In the first half of the book, he discusses why society should phase out usage of fossil fuels, especially coal, as quickly as possible in order to prevent…

    In the world’s constant desire to further grow both in the technological and economic fields, countries and their citizens often forget the environment and how necessary it is to keep human actions in alignment with the natural harmony of the earth. Through past negligence, society has brought itself to a point where action must be taken for the earth to continue to meet the people’s needs. The use of renewable resources is a very important step that many countries have promised to take,…

    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…
