CARLSBAD, Calif. -- When you see Peder Norby's Carlsbad home, you would never know that it produces its own energy.

"It's about almost 1,000 light bulbs the amount of electricity we're generating as we speak," said Norby.

Equipped with all of the trimmings, the Norbys built their Carlsbad home with planet Earth in mind -- everything from the design, to the structure and solar panels installed on the roof.

"So, for 15 percent of our total roof space, we're generating 100 percent of our electrical use," said Norby.

The home is a zero-energy house.

"You put energy in when you're having a great sunny day and then you use energy when you are not. At the end of the year, if you do it right, you'll end up like we are and with no electric bill," said Norby.

It's not just the solar panels doing all of the work. Almost everything in the home is energy efficient. The house's extra-thick walls help with the temperature.

"On the south wall we use a lot of concrete block because we want it to heat and maintain that heat. Generally throughout the house we use wood construction with insulation to keep the temperature," said Norby.

Efficient appliances like a tank-less water heater help the Norbys conserve.

"You only heat the water as you use it," said Norby.

Norby also roams around town in an electric car that is charged by electricity produced at his home.

Despite his "green" home, Norby said he doesn't consider himself an environmentalist but that every little bit helps.

"Imagine our country and our world if every home produces its own electricity and provides energy for the vehicle that it drives. So, can it be done? Yes, it can be done, and this house is an example of that," said Norby.

Norby said it won't be long before everyone can produce their own energy and never have to pump gas again.

The Norbys said they spent about $45,000 for every energy-efficient addition to their home.

But they believe they will recoup that amount within five years.
