Renewable Energy Essay: Ideas Generating Process It is a well-known fact that our standards of living depend on energy. However it is better for college and university students to express their own views. You need a huge piece of land as well as millions of investment. How can you maximize the use of solar cells? Sun energy is converted into electrical or thermal energy after it reaches earth. In this way, the advantage of solar energy is in the fact that it can be used in all the state without differences of the geographical and other specificities of the area.
For a given absorber area, evacuated tubes can therefore maintain their efficiency over a wide range of ambient temperatures and heating requirements. Solar energy is also used to heat buildings without the additions of special devices. Also solar energy does not pollute the enviornment. Disadvantages of Solar Energy Although it is hard to find a spot of the disadvantage with solar energy yet nevertheless it has certain limitations associated with it. Heated air can then be distributed directly for applications such as space heating and drying or may be stored for later use. In India, solar cookers have always been extremely popular with almost 6lakh solar cookers installed countrywide till date. Most of the environmental visionaries realized that the potential rewards of solar power outweighed the technical barriers.
In order to save the future generation from the harmful effects of fossil fuel, efforts are required at international level to promote the use of solar energy for domestic and industrial purpose. Canada has an abundance of renewable resources, including solar energy. Solar energy has been looked upon as a serious source of energy for many years because of the vast amounts of energy that are made freely available, if we use our modern technology. Even though there are many kinds of energies, there is a strong discussion about using solar or nuclear energy to provide electricity without damaging the environment in a large scale nowadays. Conclusion: The world is increasingly looking for alternate options to the coal which is a polluted source of electricity. There are several different uses of solar energy in our day to day life, such as cooking food in solar cookers, using solar energy for generating electricity as well as heating waters in large reservoirs for saving electricity and resources.
Solar photovoltaic energy is the process to convert sunlight into electrical power as energy; imitating the process of photosynthesis that plants create to survive. Solar Power is also becoming more cost effective and in the next few years it will be just as cheap to produce electricity from solar power as it will from more traditional sources such as coal or natural gas. Use of gasoline and other natural resources as sources of energy are harmful for the environment; therefore, developed countries are trying to put more reliance on solar energy for industrial usage in general and domestic usage in particular. Domestic hot water frequently falls into this medium category. Photo voltaic cells generate electricity directly using solar cells and concentrated… 2149 Words 9 Pages Dyadic Persuasive Comprehensive Outline General Purpose: To persuade Specific Purpose: To persuade my audience how to be more successful as a college student. Interesting Facts and Statistics about Solar Energy Solar energy is currently that energy market which has the potential to recreate the energy dynamics of the world.
Claim: Solar power has the potential to become the United States main supply of energy and replace are needs for more conventional and harmful forms of power generation. The requirement of solar energy in India is furthered by the need of power required for the huge industrial potential of India in the long run. In the non-concentrating type, the collector area i. An advantage of Solar Energy is that it is easy to obtain. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. Besides that, the energy network was extremely unreliable, which meant that the people who have access to electricity regularly do not have power either.
Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Narratio Every day the sun is shining and giving the Earth warmth… Words 1578 - Pages 7 Solar Energy Introduction -Sunlight is a renewable energy source which can be converted light energy into electric energy by solar panels. Many of the energy sources that supply society with power currently run on non-renewable resources such as oil and coal. This, together with the fact that solar energy power plants may be independent from the national energy grid, is a significant advantage for people in isolated localities; solar energy is more cost-effective and practical for self-reliant societies, or those who live in rural or isolated areas. Solar Energy System Solar energy system is the new source of energy used in most of the developed countries. So if dish can be aligned with its axis pointing at the sun, almost all of the incoming radiation will be reflected towards the focal point of the dish most losses are due to imperfections in the parabolic shape and imperfect reflection.
Over the history, there are many examples of using the sun as a source of energy. Only a minuscule fraction of the available solar energy is used. Active method includes the extraction of solar energy from photovoltaic cell and using the same for different purposes. Solar energy can be extracted both by active and passive methods. However, the downsides to using the diesel generators are that they are most expensive form of generation and are most harmful to the environment.
Unfortunately there are also some cons to harvesting wind and solar energy. Since there are no chemicals or gases involved in energy production on solar plants, this type of energy can be considered one of the cleanest. The sun shines almost every day, therefore providing photons to power the solar panels for as long as the sun still shines. Especially with cheaper and lucrative conventional energy substitutes being there. These photovoltaic cells utilize a semi-conductor to absorb the radiation from the sun and when the semi-conductor absorbs this radiation it emits electrons, which are harnessed as electricity.
