Heat results when photons, packets of light energy, hit the atoms that compose a substance (water, your body, asphalt), exciting them. Solar thermal technologies include passive solar systems for heating buildings (or cooling! ); solar collectors, often used to provide hot water for homes; systems and concentrating solar power. Solar energy These systems, also known as solar thermal power plants use the sun 's heat to produce steam, which then turns a turbine and generates electricity. (Fossil fuel power plants also generate electricity by first creating steam to drive a turbine.)
Coal has been the favoured source for energy generation for centuries, due to its reliability and relatively low cost. However, with coal reserves slowly diminishing due to the ever-increasing demand for energy, renewable energy sources are becoming more popular. Renewable energy is energy harvested through natural processes like sunlight and wind. These sources are replenished faster than they are consumed, and the methods used to convert them to energy do not create any pollution. Simple applications involving renewable energies range from using biomass (wood and animal dung) to fuel fires, to harnessing the power of wind in sails on ships to using the sun’s energy to grow plants in greenhouses.
Renewable energy is on demand in today’s global energy and innovation. It shows promising solution to current effort on tackling world energy problem of growing consumption and solution for a greener environment. Many developing countries is now widely researching on renewable energy based generating system to replace fossil fuel and coal based generating system. Solar energy emerges as the primary research among all other source of renewable energy due to its vast benefit. Solar energy is defines as energy in the form of electromagnetic radiation generated by the sun through thermonuclear fusion that converts hydrogen to helium (Brown, 1988).
The sun is a very valuable asset to the world today. We use it for heat, plants use it to grow, and energy such as solar power. Solar power is the conversion of sunlight into electricity. Solar power is the next alternative to all other sources of energy out there. Fossil fuels such as oil and gas are non-renewable, which means they are limited.
Solar panels are large flat panels and made with lots of individual solar cells. They can be used to heat water for use in homes, buildings, and swimming pools or to produce electricity. In the US, solar power has increased by 41% in the past few years. It has become the second-largest energy resource in the country after natural gas. By 2013, there are 445 megawatts at 950 facilities in America.
One of them is the solar energy, which works by adopting the sun raise, and converting it into energy, it is being spread out widely today. The only problems it has that it needs lots of space, and is expensive at first, but these two problems can later on help us in lots of things, people who use solar panels to their homes, can relate that their electric bills are lower than without these solar panels. It is enough that it is environment friendly, and does not cause and sounds that bother. (On the left is a picture of many solar panels). Technology still amazes us, with the help of physics, people who in this industry are working on tripling the electrical output of solar panels.
Nowadays solar energy is one of the most important sources amongst all sources of energy on the earth. This long lasting energy can be utilizes as a part of numerous perspective such as warmth and food. additionally, people can use sun`s energy indifferent ways, like remnant fuel which stored sun energy for millions years is a good delineation for this subject which can be used to produce electricity in the generators. Beyond that solar energy is clean and can generate power electricity without making surrounding pollution. In order to decrease the utilization of non-renewable energies to provide largeamount energy, one of the least complex methods to use the energy of sun is photovoltaic panels.
Solar energy is one of most important renewable energy sources that have been gaining increased attention in recent years. Solar energy are plentiful it has the greatest availability compared to other energy sources. The amount of 20% solar energy supplied in the earth. The sun are sufficient to power the total energy needs of the earth for one year .The conversion of solar energy into electrical energy has many application fields. Residential, space and aircraft and naval applications are the main fields of solar energy.
Many people also believe the benefits to solar panels are a strong reason to invest in having them placed on their homes. The average growth in residential solar power usage has increased by about 40%. Throughout this essay we will touch base on both the advantages and disadvantages to using solar
“Every second, our sun produces enough energy to sustain Earth’s need for 500,000 years”(Energy Efficient Residential Solar Power). The sun is something that we see everyday, but people choose not to use its energy to produce power in their house. Solar energy is beneficial to society by not polluting the Earth and producing more jobs in the solar industry. Solar energy is a renewable resource that can be used to power homes in efficient ways and doesn’t produce greenhouse gases. Fossil fuels release an abundant amount of carbon dioxide into the atmosphere when being burned to produce energy.
