Solar energy is renewable energy source available on Earth. This is a clean energy source that we are pushing operators. Here are some things you may not know about the power source. 1. Solar energy is the most abundant energy source on Earth, about 173,000 terawatts of solar energy down to Earth projection continuously. It is 10,000 times greater than the total energy used worldwide. 2. The first silicon solar cell is the precursor of all the solar equipment, developed by Bell Laboratories in 1954. 3. Space industry was an early adopter of solar technology. In the 1960s, space industry began using solar technology to provide power aboard spacecraft. Vanguard 1 satellite is the first satellite earth powered by solar cells. It remains the oldest artificial satellite in orbit at least from Earth than 6 billion miles. 4. Demand for solar energy is increasing in the United States. In the first quarter of 2012, the developer has installed solar panels 85% compared with the first quarter of the previous year. The total number of solar panels installed in 2012 by the US supply 3,300 MW to the grid, making the US the solar market the fourth largest in the world. 5. The cost per unit of electricity continue to decrease, solar is increasingly becoming a choice for energy savings of households and businesses in the United States. However, the biggest obstacle to get solar energy remains affordable as software license costs, planning, and bring solar energy systems to the grid. Average cost for licensing and inspection process increases the area than $ 2,500 total cost of a solar system. 6. In the Mojave Desert of California, the solar projects the world's largest under construction. The project is based on a technology called solar thermal energy. Once the project is completed 350,000 mirrors will reflect light into the boiler. When water boils, the steam turns a turbine and generates electricity. The project is expected to provide clean energy, renewable energy for approximately 140,000 households and is supported loan guarantee by the DOE.
