Tip for saving energy in the home

Replacing an electric water heater with a solar model can reduce water heat costs by 50 to 80 percent every year - and over the 20-year life of the equipment, more than 50 tons of carbon dioxide emissions will be displaced.

The efficiency of converting sunlight to electricity in pv cells

The company SunPower in 2008 announced 22% efficiency converting light to electricity. Current high-performance panels, on average, convert about 20 percent of the light that strikes it into electricity. Conventional silicon solar panels convert about 14 to 17 percent of light.

The theoretical maximum is around 26 to 27 percent, although some have said it could go slightly higher.
