Zero Energy Homes

Homes that use zero energy - ready for explosive growth?

Zero energy homes are at the heart of a California experiment drawing national attention, according to a report in the New York Times.

It represents one of the largest tests of whether the effort is ready for national prime time, experts said. The homes will rely on a mix of rooftop solar, advanced water heaters and other energy efficiency measures.

“The question that we’re trying to answer is, ‘Can it be done for everyone?’” Ram Narayanamurthy, at the Electric Power Research Institute, which is doing the study, told the Times.

California aims to have all new residences be net zero in four years.

The Department of Energy has verified that 700 homes in the country now qualify as zero or close to zero in net energy use, the newspaper said.

At the center of industry research on this front is the question of how a raft of new technologies and products interact.
