Environmental protection and no need to get fossil fuels to generate electricity; (b). Occupied less space than normal power station. The surrounding land of the wind turbine can be used for agriculture； （c）. New technology makes the extraction of wind energy much more efficient； （d）. Wind turbines are the great resource to generate energy everywhere such as mountain and countryside； （e）.
Solar energy is a natural renewable resource that has a huge potential because it can easily supply energy for the whole Earth and will never run out. The sun produces a huge amount of energy in light and heat form. It can be used by humans in several ways, for example in solar heating, photovoltaics, solar thermal energy, molten salt power plants and concentrator solar power technologies. Solar energy can either be used directly or indirectly by first turning it into electricity. Potential The amount of solar energy that is absorbed by the atmosphere is huge, about 3,850,000 exajoules (1 exajoule = 1018 joules) per year.
Renewable energy are considered to be important in improving the security of energy supplies by decreasing the dependence on fossil fuels and in reducing the emissions of greenhouse gases. The viability of isolated systems using renewable energy depends largely on regulations and stimulation measures. Renewable energy are the natural energy re that are inexhaustible, for example, wind, solar, geothermal, biomass, and small hydro generation. Among the renewable energy , small hydro and wind energy have the ability to complement each other. In a location with enough average wind speed and a suitable area for wind turbines, wind pumped storage system is a good combination with a hydro power plant.
It has a lot of positive aspects both economically as socially, because it can be used individually and is also renewable. It is also socially excepted because it does not do damage to the environment compared to nuclear power plants which has a possibility of leaking, and people do not mind the way solar panels look compared to wind turbines. Therefor I think solar energy is the best alternative energy both socially and
Energy drinks are served as cold beverages, that can be consume faster than hot beverages such as coffee or tea. 4. Energy drinks have different types of flavours and brands that can attract the consumer which hot beverages such as coffee or tea do not attract the people much. 5. Energy drinks also acts as an additional supplement to increase their effects such as vitamins, taurine, minerals and other herbs.
The little amount of carbon dioxide is produced because of the mining and construction of the power plant, however the amount released is not comparable to that of other fossil fuel. Finally, with nuclear energy, people now need not depend solely on traditional fossil fuel to generate electricity. Since the nuclear power fuel can reach a temperature in the magnitude of thousands, it can be thermo-chemically broken down into Oxygen and Hydrogen which can be used to power up vehicles Most of the world supply of uranium is in Australia and Canada. With fuel recycling, the supply of Uranium is not a
Butanol is far less corrosive than ethanol and can be shipped and distributed through existing pipelines and filling stations. Butanol solves the safety problems associated with the infrastructure of the hydrogen supply. Reformed butanol has four more hydrogen atoms than ethanol, resulting in a higher energy output and is used as a fuel cell fuel. Butanol is an industrial commodity, with 370 million gallons per year market with a selling price of $3.75 per
Cogeneration is often called combined heat and power (CHP), since most cogeneration systems are used to supply electricity and useful heat. However, the heat energy from electricity production can also be used for cooling and other non-heating purposes, so the term cogeneration is more inclusive. Cogeneration is a form of local or distributed generation as heat and power production take place at or near the point of consumption. For the same output of useful energy, cogeneration uses far less fuel than does traditional separate heat and power production, which means lower greenhouse gas (GHG) emissions as fossil fuel use is
1.1 Wind Energy System Wind is air in motion, it is due to uneven heating of earth surface by the sun rays. Since the earth surface consists of different types of land the water, it absorbs the sun heat at different rates. Wind energy is mainly used to generate electricity like earlier wind mills modern wind machines used blades to collect the winds Kinetic energy. 1.1.1 Advantages 1) The blades ere connect to shaft that turn on an electric generator to produce electricity. 2) Use of wind power to produce electricity on commercial scale has become the fastest growing energy technology.
The advantages of using Nuclear power plants: • Free from CO2 : One of the major advantages of using nuclear power plants is that, it is free from carbon-di-oxide emissions. Most of the conventional methods of generating electricity include the usage of non- renewable resources like coal which generates CO2 upon usage. • Very efficient source of energy: The energy produced by the fission of an atom of uranium or plutonium or any other element used in the process of nuclear fission for generating energy, I almost 10 million times the amount of energy produced by combustion of a single atom of carbon in coal. It also doesn’t result in the depletion of fossil fuel reserves. Hence one can obviously see the efficiency and the effectiveness of using nuclear power plants for producing heat and
