Tidal Power

The generation of electricity mainly depends on the quantity of precipitation that falls in a specific area. In 2011, a tidal plant with 254MW began its operation and it has doubled the capacity through out the world to 527MW.

In the disadvantages of hydro-energy, dams are extremely expensive to build, and must have high standards. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydropower schemes can go ahead. (Technologystudent.com, 2015). Building dams can also create natural disasters such as earthquakes.

2. tidal currents that pass through narrow channels can be used to turn underwater pivoting turbines, which produce energy. potential for usable tidal energy increases with an increase in tidal range because a higher tidal range means more water moving in and out of the turbine system.

Hydroelectric energy is used the most in France because France is trying to use more renewable energy sources. Due to the Kyoto Protocol, France is developing a new system of energy-related research and development for renewable energy sources. (Campus France)

Some cons that hydropower has include; Environmental impact, Displaced people, and Accidents. The environmental impact would be before producing hydropower, it is necessary to build a dam, changing water levels and flooding large areas. It is also necessary to build roads and power lines. This has a strong impact on wildlife and the ecosystem. When building a dam the construction of a large dam often requires that entire towns move out of the area. In the construction of the Three Gorges Dam it is estimated than 1.2 million people were displaced. lastly , in the past old dams often suffered breaches which led to floods and

When there is no water to produce hydro-electricity there will millions of people without electricity. Therefore, the amount of droughts that are caused by hydro-electric dams prove that they are not environmentally responsible. Hydro-electric dams are not an environmentally responsible form of energy because they will cause massive floods. The La Grande dam project in Quebec has already flooded over about 10,000 square kilometres of area around the dam. The hydro-electric dams are producing large amounts of floods which are starting to cover large amounts of agriculture and forestry. It is has also been said that if there are more dams created in the area it will cover up to 41,285 squared kilometres of land. Finally, the hydro-electric dams are not an responsible form of energy due to the amounts of floods they can create.

The Bonneville Dam has an energy block with gates and locks used for shipping and transportation. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The first power generated at the Bonneville Powerhouse was produced in March 1938. Since the dam poses a negative impact on the migration of sturgeon and salmon, a fish elevator was created to assist fish in returning to streams to reproduce. In 1986, the dam along with the fish hatchery become historic sights.

“Tidal power generates energy from the tides moving in and out…wave power generates energy from the rise and fall of waves.” (Cunningham.) Capturing the ocean’s movement is a great form of renewable energy with waves never running out and that they are available in many areas of the world. There will be no byproducts that will be harmful or will pollute the environment, and to receive the energy there can be many different gathering techniques. In retrospect towards marine growth, submerged wave energy converters will make “safe havens” because they will become artificial reefs with a closed off surface areas. “They insist that if all 28,000 miles of U. S. roadways are covered in these solar cells, it would generate three times more power…” (Cunningham). The hexagonal solar panels would be able to make more productive areas such as a solar parking lot, additionally paying for themselves and power other homes or businesses. In order to improve the safety of every community, there would be heating elements to keep roads snow/ice free, and LEDs to make road lines. There is little maintenance to ensure that the solar panels are in working order, and they are a silent producer of energy. When compared to burning fossil fuels in power stations, solar energy stands out by the fact that it saves money and gives energy security in households. “Human waste is taken to a treatment plant…methanogens go to work…methane is produced as a byproduct.” (Cunningham). Currently, over 200 millions tons of human waste go untreated, and once they get into the clean water, many die from diseases in contact with the fecal matter. When methane is burned as electricity, there would be a decrease in treating water and disposing

According to solarhome, the term solar power more specifically refers to the use of the sun’s energy for electricity.

The need for electricity is greatly increasing as the population and demand is rising each year. Coil power may be a thing of the past with government restrictions imposed. Now is the time to starting increase the supply sources of alternative energy, renewable energy. This paper will show what a great resource the Hoover Dam is not only in providing energy to multiple states but by offer other great features as well.

Hydro-electric schemes usually rely on the construction of dams which can have significant effects on river flows, water quality, flora and fauna

Renewable energy is energy that comes from any natural process and can be quickly regenerated. Some of the most common forms of clean energy include solar energy, wind energy, and hydroelectricity. These types of electricity are gathered through technology such as solar panels, wind turbines, and hydroelectric dams. Other types of renewable energy less known include geothermal energy, biomass energy, and energy collected from ocean (Renewable). Geothermal uses the Earth 's heat to generate energy while biomass use plants and other organic materials to make energy and fuels. Ocean energy can be derived from a multitude of areas. Energy can be gathered from the tides, the wind, and can also be gained from the

For renewable sources of energy it is the most reliable even though it is variable. Different power generation methods have finite resources that will eventually run out. Other renewable energy resources while powerful are either unreliable such as wind are not always available such as solar energy. Through the use of dams we can store water to be used when needed to supply the demand caused by energy consumption. Using gravity water is allowed to flow through a turbine causing a generator to make electricity. When demand is low the water can be pumped back up into the containing reservoir to make another hydroelectric head. This process can just be continued creating a reliable capacity of energy. In the use of tidal power generation electricity comes in and out with the tide. There is a small marginal effect on the environment because no emission or hazardous waste is being made. While most prime locations for traditional hydroelectric power plants are already taken, there are plenty of locations to be used for tidal power generation. Once the technology to build underwater structures that are able to last against the harsh waves is more manageable there will be plenty of new location ready to be taken throughout the ocean. These generation plants will just be using water and gravity to supply power to meet the ever growing demand of the population. Using water to it full advantage in every facet possible from traditional hydroelectric pumped storage, run of the water types, tidal barrage using shoreline bays and tidal current using the oceans current will make it the greatest resource on

Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.

In 1831, scientist Michael Farday discovered the first form of electricity. He found that when a magnet moved inside a copper coil it created what is known as an electric current. This invention is known as a turbine generator. Even today, in full sized power stations this simple invention is still used and works very effectively. These power stations create mass amounts of energy to turn the turbines. Most of the time the energy is made from the heat, for example when coal is burned. More environmentally friendly power stations use wind or flowing water to turn these turbines. This is known as renewable energy because it will not run out, unlike when oil and coal are used.(3)
