Real estate companies are racing to install solar panels on office buildings. Utilities are erecting large solar panel “farms” near big cities and in desolate deserts. And creative financing plans are making solar more realistic than ever for homes.
Solar power installations doubled in the United States last year and are expected to double again this year. More solar energy is being planned than any other power source, including nuclear, coal, natural gas and wind.
“We are at the beginning of a turning point,” says Andrew Beebe, who runs global sales for Suntech Power, a manufacturer of solar panels.
Solar’s share of the power business remains tiny. But its promise is great. The sun splashes more clean energy on the planet in one hour than humans use in a year, and daytime is when power is needed most. And solar panels can be installed near where people use power, reducing or eliminating the costs of moving power through a grid.
Solar power has been held back by costs. It’s still about three times more expensive than electricity produced by natural gas, according to estimates by the Energy Information Administration.
