The Solar Of Solar Energy

The creation of solar energy requires little maintenance and solar electricity power plants produce zero emissions. Solar power plants use two different types of technologies: Concentrated solar power and Photovoltaic systems. Concentrated solar power plants, also known as “concentrated solar thermal”, uses solar thermal energy to make steam that is converted into electricity by a turbine. A photovoltaic system, also known as solar panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy.

analysis has incontestable that solar energy is a perfect supply for lowtemperature heating applications like area and domestic quandary heating. Solar heating applications area unit intuitive since, once solar power is absorbed on a surface, the surface temperature rises, providing a heating potential. The use of solar energy to supply refrigertion is a smaller amount intuitive.

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.

The solar industry is divided in three main markets: the European solar thermal market, the Chinese market and the market in other world regions. The industry is segmented in two main types of solar thermal collectors, which are evacuated tube collectors (80 per cent on average of the worldwide newly installed capacity in 2010) and flat plate collectors (20 per cent on average). This industry is characteristic of technology intensive industries with their central innovation: solar thermal water heating which radically reduces costs. They can also count on experimented installers. Each customer adopt and have

There are two main forms of solar power: The use of photovoltaic, or PV, cells, and the use of thermal energy from the sun. Photovoltaic cells exploit the photoelectric effect, which converts the protons from the light of the sun into electrons, which can be converted into energy. Photovoltaic energy accounts for fifteen gigawatts of global energy, which is equivalent to fifteen large electric power plants. Also, the production of PV cells has increased by two thousand times over the past twenty years, and it is expected to continue to grow. Solar-thermal energy takes the thermal energy created by the sun and turns it into electricity. Although it only only produces as much energy as one large power plant, solar-thermal energy has many domestic uses. It can not only be used for electricity, but also for solar heating, which uses sunlight to heat up houses. Solar power has already proven to be a reliant source of energy, and it will only continue to improve in technology and

Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is

Solar Thermal Power systems, also known as Concentrating Solar Power systems, use concentrated solar radiation as a high temperature energy source to produce electricity using thermal route. Since the average operating temperature of stationary non-concentrating collectors is low (max up to 1200C) as compared to the desirable input temperatures of heat engines (above 3000C), the concentrating collectors are used for such applications. These technologies are appropriate for applications where direct solar radiation is high. The mechanism of conversion of solar to electricity is fundamentally similar to the traditional

In the last decades energy consumption has come to a time where people started noticing the climate changes and the effect of fossil fuel energy for not only being environmentally destructive, but also causing Global warming (the warming that occurs as a result of increase emissions of greenhouse gases) has become a very big issue worldwide. The fossil fuels (Oil, Coal, and Natural Gas) which is the main sources of the world’s energy sources, is also one of the main causes of the climate change. In addition with some human activities (e.g. through burning fossil fuels), they have contributed immensely to the global warming, which has also affected the climate conditions in the world. The affect of these changes has prompted some people to propose alternative energy like solar panels. According to Abby Gruen, after realizing the issues, the engineers at Bell Laboratories come up with the first useful photovoltaic cell, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panel which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel, solar panels is less harmful for the environment. Since it creation few decades ego, just recently solar panel started getting popular in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price has changed dramatically since then. Even though

If the sun gives energy to the solar panels while the electricity is not being used, “the generation exceeds the demand, the energy is stored” (Bazan). However, storage does not have a huge capacity for energy to be stored. Once our society uses solar panels, they will help improve the quality of the environment and our health. Although the goal for solar panels is to help save the environment, they have some disadvantages. However, scientists are researching and experimenting to change those disadvantages into advantages. Scientists see in the future, “renewable energy-driven systems are poised to gain popularity” (Bobovych). If solar panels gain popularity, they will impact our society by having them everywhere.

“Even if we didn 't have greenhouse gases, were going to have to move away from fossil fuels, as we 're going to run out. They 're finite, where as solar and wind are infinite.” - Ted Turner. Solar panels use the energy that comes from sunlight to give power. Low-temperature collectors are flat plates generally used to heat pools. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. High-temperature collectors concentrate sunlight using mirrors and lenses. and are generally used for fulfilling heat requirements up to 300 deg C / 20 bar pressure in industries, and for electric power production. Installation of solar panels costs 15000 to 40000 on average. Solar

Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.

The U.S. Energy Future is one of the most talked about subjects in science. There are many different types of alternative energy to using fossil fuels. Scientists have warned the population that the fossil fuels that we current use for our main fuel source may run out in less than 100 years (James Trefil & Robert Hazen, 2013). While the fossil fuels are readily available to our current generations, we need to start making great results in switching our main energy source to more renewable energy for our future generations. I have researched a few of the most popular alternative energy sources for the U.S. future.

They say the greatest thing about our Universe is its ability to produce certain renewable energies which is then used by humans. There are numerous amounts of renewable energies found in the world. The sun, wind and tides in the oceans are just some of the many kinds . The sun alone does so much in the environment that may sometimes go unnoticed. its one of the many things some humans take for granted. Humans use the sun for various reasons, to tan on the beach, or even for their basic vitamin D. The sun triggers photosynthesis in the chlorophyll molecules of green leaves , a reaction that produces carbohydrates which is initially the basis for all terrestrial life. Scientists’ say it takes millions of years for the energy found in the sun’s core to reach the solar surface, following that it takes a bit over eight minutes to travel the 98 million miles to earth. The amount this solar energy travels to earth is approximately the speed of 186,000 miles per second, measured in the speed of light (Telstar.ote.cmu.edu, 2014). The sun is amazing itself, it provides so much for the living organism on planet earth and the most important energy formed is solar energy. Solar energy is also the strongest/ most powerful of all renewable energy resources in the world (Writer, 2014).

A solar thermal collector collects heat by absorbing heat from sunlight. A collector is a device for capturing solar radiation.

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.
