Energy efficiency is essential to provide citizens with functioning electricity and fuel. The

Moving into the next renewable energy, there is a big advantage that hydroelectric power is that hydropower dams is a huge renewable resource and using water to create electricity has no carbon footprint. As well as there is less pollution from it overall. There are many advantages but there are two distinct disadvantages, one of them being the cost to build an electric power station. The cost

Hydro-electric dams are not an environmentally friendly form of producing energy because is will cause people to relocate. In Canada, there was a dam approved to be built in 1958 which caused over 6,500 people to relocate. Hydro-electric dams need large amounts of water in order for the dams to meet the electricity required. Therefore, they need large reservoirs. These big reservoirs and high amounts of water decreases the land area for people and animals to live in. In conclusion, hydro-electric dams are not an environmentally positive form of generating energy, it will cause people to relocate.

I feel that hydroelectric energy would be the most beneficial for the city of Memphis. The reason I feel that hydroelectric energy would be helpful for Memphis because Memphis is located along the Mississippi river. So it would make most sense for us to use hydroelectric energy because there is a huge river in our city. We would not run out of recourses for a very long time, because water is renewable. We would have easy access to the water and we would have enough of it to power the whole city.

Many people have been contemplating about which energy source would be the best to use, but a proper decision hasn't been made. Every energy source has their own benefits which contribute to a healthier environment, but with every benefit, there is a drawback. Not every single energy source is available everywhere. Solar panels would be inefficient in a constantly cloudy area, and a wind mill would be incompetent in stagnant air, as a hydroelectric dam would be incapable of anything in a desert. One peg couldn't sustain every peg hole at one time. Transporting the electrical energy would cost more money, which could become a disadvantage over time as the generators that transform the energy already are costly. Even though a great deal of time and effort have been put into thinking which energy source is better overall, the answer is still unknown since everything comes with it's own problems, so I have chosen the ones that I believe are more efficient with nature and costs.

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

Hydroelectricity is electricity generated by hydropower, the electricity is created by using the gravitational force from falling or flowing water. Throughout the entire world it makes up 16% of the renewable energy used making it the most widely used source of renewable energy. In 2010 there was 3427 terawatt hours and with a power plant larger than 10 megawatts it costs 3 to 5 US cents per kilo watt which also makes hydroelectricity one of the cheapest forms of energy. Hydroelectricity is expected to increase 3.1% each year for the next 25 years which eventually means we will be producing enough electricity to power over 1000 United States. Looking at the stats hydropower ranks first among all other renewable energies and if we keep up and continuing to put in power plants hydropower can continue to stay on top of all the other renewable energies.

Clean and safe energy Unlike the use of fossil fuel, biomass, and nuclear as a source of energy, hydroelectric energy does not have waste products. No emission and radiation are harmful to the environment and people, making it a clean and a green source. Therefore, future generations can use enough energy.

Hydro Energy is stored by water flowing through a dam and having energy stay in it’s area of generators. Its energy is released by generators turning and making electrical shock waves to create power. This resource produces about .85 cents per kilowatt hour. For this it depends on how big the power plant is and how many generators you’ll need.

While energy efficiency helps save money at home, it also helps businesses, cities, state, and the federal government save on a much larger scale. Overall, energy efficiency is saving the American government, its citizens, and businesses more than $500 billion a year in energy costs. Efficiency saving money, energy efficiency projects like building improvements and infrastructure repairs create jobs. According to http://www.ase.org/resources/top-5-reasons-be-energy-efficient, “In 2010 alone, energy efficiency accounted for more than 830,000 jobs nationwide.”

One major advantage standpoint with the use of renewable energy is that as it is inexhaustible it is accordingly feasible thus will never run out. Renewable energy offices largely require less upkeep than conventional generators. Their fuel being gotten from common and accessible assets lessens the expenses of operation. Much more vitally, sustainable power source creates practically no waste items, for example, carbon dioxide or other synthetic toxins, so has insignificant effect on nature. Renewable energy activities can likewise bring financial advantages to numerous local regions, as most undertakings are found far from expansive urban focuses and rural areas of the capital urban areas. These financial advantages might be from the

One reason for supporting hydropower is that it’s renewable. Hydroelectricity means electricity that is created from water, with “hydro” meaning water. Hydroelectricity depends on the kinetic energy of moving water in order to function and produce energy. In order for this to occur, a dam is built on a source of running water, like a river, to create a reservoir of water. This reservoir is constantly renewed through the water cycle, which is an endless cycle where water constantly evaporates to form clouds, which eventually falls back as precipitation into streams and rivers . Because of this constant renewal, water will never run out. In this case, the water falling back as precipitation always refills the reservoir. The moving water then spins the blades of a turbine, which turns a shaft in a generator, which generates electricity that eventually travels through wires to

All the benefits that electricity can provide us are seen in everyone’s daily lives. It can include all types of electronics, appliances, lights, providing power to non-industrial and industrial electric cars, machinery, etc. There are a lot of key things connected to this. One of the key things is the power plant that provides electricity. While some are eco-friendly, some may affect the environment. Many environmental organizations are most recommended as an option for the eco-friendly. The options include wind, hydroelectric, solar, tidal and geothermal. I think solar energy is very popular in a global scale and in Bangladesh. Solar is used my solar panels which absorbs photovoltaic cells and it transfers to electricity. There is this foundation called the “Bright Green Energy Foundations” and according to that, over 400,000 home systems has been installed for people in the rural areas who cannot

Hydropower relies on the water cycle, which is driven by the sun, thus it's a renewable power source. Hydropower is a fuelled by water, so it's a clean fuel source. It is better for the environment than other major sources of electrical power, which use fossil fuels. Hydropower plants do not emit the waste heat and gases—common with fossil-fuel driven facilities—which are major contributors to air pollution, global warming and acid rain.

For the energy savings we need to promote the use of new and renewable energy sources. Reasonable arrangements for cities’ various functions, and promote urban living, employment and other rational distribution, reduce traffic load, reducing energy consumption in urban transport. Renewable energy means that the energy is from nature, non-fossil energy sources can be renewed, including wind, solar, hydro, biomass, geothermal and ocean energy.
