What is solar electricity?

solar electricity concerns the energy derived from the sunlight used to produce electricity. Since antiquity, solar heat and light in many ways have been used in many ways. In the last decades, however, have technologies such as photovoltaic or solar cells, have solar energy to help supply electrically dependent equipment, vehicles and even whole houses. Because it is a renewable source, solar energy is generally preferred to non -renewable fossil fuels such as coal and oil. In addition, most solar technologies used to collect and convert solar electricity do not have moving parts and do not cause any noise or pollutants, making them an attractive alternative energy source for fossil fuels. Depending on the way these technologies capture, convert and distribute solar energy, they are considered active or passive solar energy. Photovoltaic and solar thermal unit are consideredAs active solar energy, because these devices directly collect, transfer and distribute the energy of the sun as electricity. Passive solar methods may include designs of houses that include the presence of abundant sunlight to ensure natural light and heat inside the structure.

Earth around the world began to receive solar electricity as an alternative to fossil fuels. While the cost of installing solar power plants, such as photovoltaic fields and solar troughs, can be considerable, long -term benefits of solar electricity include less dependence on non -renewable sources, and therefore less pollutants or by -products. Solar electricity is an intermittent energy source, which means that one can easily predict if the sun is and does not generate energy in specific regions. This ability has helped solar engineers and ObsaThe Best Technology and Places for Grees for Sun Energy.

In addition to the use of solar electricity for power, heat and cooling the house, there are various other solar energy applications. Continents, including Australia and the United States, organize competitions since the 80s. Similar competitions for solar ships and other vehicles were organized.
