The house uses L-E-D lighting and has a geothermal heating and cooling system. It is solar-powered. The solar system provides the energy needed for the house and an electric vehicle.
Michael Koenig with Honda Smart Home U.S. says every year the system is expected to produce two kilowatts of electricity more than it consumes.
"This is the vision for how can we achieve net-zero carbon, not just net-zero energy, but how can we get to zero or below zero carbon for the future. And there's a lot of ways to do it. There's a lot of smart people working on it.
A UC Davis employee will live in the house for several months and assess its livability.
The house has hundreds of sensors which can trigger automatic lighting and record information about the viability of new products.
It has other efficiencies. The slab of the home was poured using a new cement mix that requires fewer carbon emissions. Gray water will be used to water the landscape.
Della Thompson is in real estate. She was one of about 60 people who took a tour during an open house.
"It would be great if it was available to everybody. The problem's going to be to make it cost-effective where it doesn't price everybody out of California," she says.
Honda won't say how much the house cost, but it does say it hopes the research will help make the efficiencies standard for new homes within ten years.
The home is the newest addition to the West Village community at U.C. Davis. The school says the development is on its way to becoming the nation's largest net-zero energy community.
A collection of environmental, fishing and whitewater groups recommends changes to dam management in a new report, issued in response to the failure of the main spillway at Lake Oroville in February.
Traditional methods to cool cows use 11,000 gallons of water per cow per year. UC Davis researchers are trying out new techniques that use less resources.
Caltrans is worried about the possibility of dead trees falling onto some California highways. The agency has already removed 107,000 trees. Now the agency is getting ready to remove another 54,000 trees, including some on private land.
A federal water bill that supporters say will streamline dam and water storage projects in California faces an uphill battle in the Senate. One of the largest water suppliers in the state says it's unlikely to support it.
Summertime is a favorite for tourists at Lake Tahoe, but the region's transportation system is not designed for the growing number of people who use it. The TRPA and TERC are coming up with a plan to fix the gridlock and improve the lake's clarity.
