GREEN BUILDING TIP: Sell Energy to Your Utility Company

Many states now have "net metering" laws forcing power companies to buy your excess energy from the sun or wind

Photovoltaic panels and are one of the design cornerstones of zero-energy homes, which produce as much electricity over the course of a year as they consume.

Installing enough PV to accomplish this costs tens of thousands of dollars, but as the price of photovoltaic modules continues to fall and efficiencies go up, net-zero performance will be available to many more U.S. homeowners.

In addition to incentives and rebates
, net metering laws can help ease the cost of producing your own power.

These laws require utility companies to buy electricity generated on-site from customers at the full retail rate. Typically the electricity meter runs backward when power is flowing into the grid (such as sunny or windy days), which offsets the amount of electricity you have to buy at other times (at night or when the wind isn’t blowing).
