  1. Solar energy is the most abundant energy resource on earth — 173,000 terawatts of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use.

 

  1. The first silicon solar cell, the precursor of all solar-powered devices, was built by Bell Laboratories in 1954.

 

  1. The space industry was an early adopter of solar technology. In the 1950s, the space industry began to use solar technology to provide power aboard spacecraft. The Vanguard 1 — the first artificial earth satellite powered by solar cells — remains the oldest manmade satellite in orbit — logging more than 6 billion miles. Current satellites is also using solar energy to be able to fly more distant planets.

 

  1. Fast track to today and demand for solar in the United States is at an all time high. In the first quarter of 2012, developers installed 85 percent more solar panels compared to the first quarter of last year. Total U.S. installations may reach 3,300 MW this year putting the country on track to be the fourth largest solar market in the world.

 

  1. The number of people using solar energy in Korea and Japan is over 50%, this figure respectively well with the developed countries in Europe such as Germany or the Netherlands.

 

  1. As prices continue to fall, solar energy is increasingly becoming an economical energy choice for American homeowners and businesses. Still, the biggest hurdle to affordable solar energy remains the soft costs like permitting, zoning and hooking a solar system up to the power gird. On average, local permitting and inspection processes add more than $2,500 to the total cost of a solar energy system.

 

  1. In California’s Mojave Desert, the largest solar energy project in the world is currently under construction. The project relies on a technology known as solar thermal energy. Once the project is complete 350,000 mirrors will reflect light onto boilers. When the water boils, the steam turns a turbine, creating electricity. The project is expected to provide clean, renewable energy for 140,000 homes and is supported by an Energy Department loan guarantee.
