Solar energy is energy that is harnesses from the Sun. The technologies harness the sun’s incredible energy for practical ends. Solar power plants use a variety of methods to collect sunlight and convert this energy into electricity.

While the use of solar energy has been used for millennia, it’s potential has only been recognized within the past few decades{readmore}, when it played an essential part in the success of early commercial satellites. After the Solar energy collected, it is most often stored as heat in the thermal mass of buildings, however batteries, water tanks, and other storage facilities can be used to store energy in thermal and chemical forms.

Solar energy provides an energy efficient and environmentally friendly power source and it has satisfied the demands of activists for an eco-friendly world. Solar energy has also become an attractive solution to global warming.

Solar energy is the solar radiation that reaches the earth. The technologies have great potential to benefit our nation because it can be used in both large-scale applications and in smaller systems for the home.

Solar energy has many different advantages over conventional energy; The biggest one being that the energy from the sun is virtually free after the initial cost has been recovered.

Photovoltaic is a process where solar cells directly convert sunlight into electricity. Solar energy collected in photovoltaic cells can be used to produce electricity for a number of uses, including: remote area power supply systems such as remote farms or in national parks electricity supply in urban areas electric fencing and telecommunications.

Photovoltaic energy is the conversion of sunlight into electricity through a photovoltaic (PVs) cell, commonly called a solar cell. This process is gaining credence among private investors as having the potential to grow into the next big industry.

Photovoltaic cells, like batteries, generate direct current (DC), which is generally used for electronic equipment. The photovoltaic cells that convert sunlight directly into electricity and are made of semiconductors such as crystalline silicon or various thin-film materials.

Photovoltaics can provide tiny amounts of power for watches, large amounts for the electric grid, and everything in between. It is an incredible procedure that may very well end our dependence upon fossil fuels.

Photovoltaic systems provide a unified solution, bringing power to these that need it, while making a moderate but important contribution to climate protection.

In 2006, the Los Angeles Department of Water and Power in an alliance with General Electric, went forward with a 120 megawatt wind farm, named the Pine Tree Wind Project. It is hoped that it will one day satisfy 20 percent of the utility’s energy requirements.

Back in 2004, wind energy in the whole state of California produced more than 4,200 million kilowatt-hours of electricity, approximately 1.5 percent of all electricity generated. More than 90 percent of all of the state’s wind generating apparatus is located in three regions: Altamont Pass, San Gorgonio and Tehachapi.

Wind power plants are comprised of turbines that take advantage of the energy in wind motion to make mechanical energy, which is then converted into electrical energy. Wind turbines can be placed near farms, homes and businesses in breezy locations, such as along the Los Angeles coast. Turbines are deployable in areas where it isn’t cost-efficient to place power lines.

The parts of a wind farm include turbines, which feed through an underground power conduit and a connection from the farm to the closest power grid. Wind power is more accessible in certain seasons because the climate affects wind speed. In Los Angeles, speeds are highest in the scorching summer period. An estimated three-quarters of all yearly wind energy is generated during the spring and summer.

Though power created by older wind turbines is not as cost effective as some other forms of energy generation, new generation wind turbine designs should be able to compete with power costs from nuclear and coal plants.

Some advantages in utilizing wind energy include: replacement of polluting conventional power plants; no pollution in the air, soil or water; it is completely renewable; the installment is relatively swift; and energy production not swayed by gas and oil price increases.

However, there are some issues with wind power, such as: the required use of extensive tracts of land, albeit the fact that simultaneous land uses are available for such tasks as agriculture and cattle grazing. Other potential concerns are that it can cause erosion in desert areas, and disrupt wildlife habitats.
