Pioneers show Americans how to live "off-grid"

Rosen also believes that more people still hooked up to the utilities will switch to energy saving appliances, saving money and becoming "off-grid ready" in the process.

"I wouldn't take their electricity if they brought it to my back door. Living like this is financially and mentally very healthy."
