Resource potential is huge.
The potential for just offshore wind would generate four times the U.S. power used in 2012.
Thats 17 quadrillion watts of electricity!

Most abundant energy resource on Earth

173,000 terawatts of solar energy strikes the Earth continuously


More than 10,000 times the world's total energy use.
Solar =
Sun

85% increase in 2012

3,300 megawatts total

U.S. 4th largest market

75% decrease in cost

since 2008
Converting sunlight to usable energy...
In one hour, enough sunlight reaches the Earth's surface to meet the entire world's energy needs for one year.
Concentrating Solar Power

PV comes from the process of converting light (photons) to electricity (voltage)

Called the PV effect

space satellites
calculators
watches
homes
Solar Photovoltaic (PV) Cells
electricity
Demand for solar energy is currently greater than supply.
Although investment in solar panels is high, energy from the sun is free!--Money will be saved in the long run.
