Dan Burr lives off the grid in Damariscotta using wood to heat his home and solar panels for electricity.

Burr opens up the cover to his battery bank in the basement of his home. The technology inside electric-car batteries is sparking a revolution in how energy is stored for when the sun is not shining.

A wood stove is used as the primary source of heat in the Burrs' home.

Burr demonstrates how he changes the angle of the solar panel at his Damariscotta home.

Burr uses a power system monitor to regulate his home. The cost of solar-electric panels has fallen drastically over the past few years, so homeowners can generate more power for less money.

With the help of a battery bank Burr and his wife, Joyce, have lived off the grid for six years.
