Solar energy is a renewable, clean energy that is around for millennium in one form or another. Following is a review of solar energy.
Solar Energy Overview
Solar energy is focused on harnessing the strength of the sun to produce energy. The sun rains enough solar energy on the Earth in one day to power the entire energy needs around the globe for one year. Solar energy is considered a renewable power source because it will exist provided that our sun does, estimated to be another 4.5 billion years. Solar energy is also considered a clean energy because very easy produce pollutants or byproducts harmful to the environment.
Solar energy was the first energy source used by mankind. Of course, the use was limited to drying things and heating caused by direct contact, but it was a use. Today, solar energy is a huge power source since the early 1950s, but was not widespread due to technological issues which rendered it an ineffective and expensive energy source. With technology advancements, solar energy is moving to the forefront as a potential alternative to fossil fuels.
The future is indeed bright for solar energy as new solar nanotechnology is close to creating solar platforms that boggle the mind. For instance, a few companies making the effort to create solar quantum dots, which will be mixed in the paint you use for your home. Yes, you will actually paint on solar energy panels that will power your home
Currently, solar energy is produced primarily using solar cells, also referred to as photovoltaic cells. The process works by placing the cells in direct sunlight. Sun hits the cells causing a chemical reaction that creates an electric current. The current is then turned into electricity. The problem with these cells, however, is they are only about 15 percent efficient.
Solar energy is typically classified in two ways, passive solar and active solar. Both approaches produce solar energy, but in very different ways
Passive solar is what it sounds like. Very easy involve panel systems or other moving mechanisms to produce solar energy. Instead, passive solar involves planning a structure so as to capture the potency of the sun with windows, tanks and the like. These systems may be used to heat homes, water etc.
Active solar energy systems typically involve some sort of solar panels. The panels are oriented to maximize exposure to the sun. With respect to the system, the panels will then either directly converts sunlight to electricity, which is then transformed from direct current electricity to alternate current electricity and stored in batteries or fed into the grid system of the local utility. Active systems will set you back and complex.
Solar energy has numerous advantages over other energy platforms. It is produces no pollution, requires little maintenance and comes with significant financial incentives as tax deductions, tax credits and rebates from manufactures. In most states, solar energy may also be sold back to utilities per a concept known as net metering. This reduces the requirement of batteries and significantly cuts utility bills.
Unfortunately, solar energy has some disadvantages as well. The initial cost of purchase and installation can be expensive. Second, areas with limited sunlight are problematic. Third, solar energy obviously can't be produced at night. Despite these disadvantages, solar energy is a booming energy platform.
The largest producers of solar energy on the planet are Germany, Japan and America. California has recently introduces a solar initiative devoting over three billion dollars to promoting solar energy use by residents in the state. As this overview demonstrates, the solar energy platform is coming on strong. - 42629
