The Best Type Of Energy

Solar energy can save us. Solar energy can reduce pollution by burning fuels in extoridant

The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.

A solar photovoltaic power system is a technology that converts the energy from sunlight into electrical energy. Residential solar photovoltaic systems can offset much of a household's power needs, depending on the size of the system and the household's needs. The output power from is directly proportional to power received from the sun, which varies throughout the day and year. The rated maximum output of the module might be achieved only occasionally, depending on actual site conditions. It is a renewable source of energy that is sustainable and totally inexhaustible. Solar energy is also a non-polluting source of energy that doesn’t emit any greenhouse gases when producing electricity.

Solar power is the most abundant most renewable resource that we have and it is free. The process starts when the sun shines on Solar PV panels that have been installed on your roof. Photovoltaic refers to the scientific process by which solar energy is converted into electricity. There are a number of silicon cells within each PV panel. These react with photons, or units of light, from the sun to produce direct current or electricity. DC electricity then travels to an inverter, which converts this energy to electricity known as alternating current or AC that can be used in your home or office. AC electricity then travels to the distribution network in your home powering your domestic or office appliances. When your solar panels produce more electricity than your home or office is using, the extra electricity gets fed back into the national grid. Yet, there are many processes the PV cell actually goes through to produce power of electricity. The top and bottom layer of the PV cells are protective glass layers with conducting coding’s. Electricity in the form of electrons flows in and out of these conducting coding’s while electrical production process happens in the middle layer of the PV cell. At the molecular level, a photon strikes a dye molecule absorbed on the surface of the TiO2 causing an excited state, which releases an electron into the TiO2 that exists through the conductive layer. The

Solar energy is rising throughout the United States. This source is mainly used in remote locations, but is becoming popular in urban areas. In 18 days of sunlight the earth receives an equal amount of energy stored in all of the earths reserves of oil, coal, and natural gas. Solar energy is produced by collecting sunlight with large, flat panels, made up of individual solar cells, and converting the sunlight into electricity. Solar energy is an alternative to fossil fuel and it is important to know the advantages, disadvantages, and the overall price.

Solar power, or photovoltaics use light as a source of electricity. The photoelectric effect, discovered by Edmund Bequerel in 1839, shows that some materials have the ability to release electric current when subjected to light. Solar cells consist of semi conductors that are specially treated to create

From this study, it was concluded that the hazardous emissions that are connected to photovoltaic technology are only connected the consumption of energy in the manufacturing process. In 2010, a research project was funded by the Clean Energy Fund. This project only focused on understanding the effects of photovoltaic to the environment. According to this research, photovoltaic energy is in a perfect position to be included in low carbon energy technologies to sustain future energy. The study also concluded that the amount produced was too low to pose adverse effect to the environment.

As we all know that, history of solar energy is as old as the humans. Since last two centuries human beings started to use it in order to generate electricity. We get electricity form the sun, directly by some simplest processes or else we can get it without any processes too. ‘Many materials produce small amount of electricity when they are exposed to the light’ – this was discovered by Alexandre Edmond Becquerel in 1839. Photovoltaic (PV) converts sunlight into electricity. Sunlight based power is apparently the cleanest, most dependable type of renewable energy accessible, and it can be utilized as a part of a few structures to control your home. Sun powered controlled photovoltaic (PV) boards change over the sun 's beams into power by energizing electrons in silicon cells utilizing the photons of light from the sun. This power can then be utilized to supply renewable energy to our homes. Solar panels are the devices that convert light to electric energy, which are called "solar" panels. The powerful source of light is available from the Sunlight, which are called Sol in technical world.

The world has giant solar energy resources that haven 't been greatly used so far. Alternative energy presently accounts for a tiny share of world primary energy consumption, however its use is projected to extend powerfully over the outlook amount to 2030.

energy represents almost a half of one percent of the total electricity use, a number that is insignificant (Diane and Shubhayu 12). The human population is yet to realize that solar energy can be used extensively in both heating and lighting. Moreover,

Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.

The most common form of solar energy used today are photovoltaic solar panels, which absorb the sun’s light to create electricity. These solar panels can be attached to homes as a primary or secondary source of electric power. They can also be used for small appliances and machines which only need small amounts of electricity for use. Large scale photovoltaic panel plants have also been constructed to provide power to many homes.

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
