From the outside, the rows of tile-roof houses in a new community in Menifee, Calif., don’t look much different from those in other subdivisions cropping up in this fast-growing city in Riverside County. But on the inside, these all-electric homes are revolutionary, offering a glimpse of the zero-emission future we should be hurtling toward to fight climate change and adapt to its effects.
All the houses in the Durango and Oak Shade at Shadow Mountain communities, two adjacent KB Home subdivisions I visited in May for an opening event, were built without natural gas hookups or appliances. Each of the 219 homes comes with rooftop solar panels, heat pumps for heating and cooling, induction cooktops and other energy-efficient electric appliances, and a smart electrical panel that manages energy use. In the garage is a battery storage system that can power the home during an outage and in the evenings when the cost of electricity from the grid is higher.
I expected these homes to come with a premium price tag, given their futuristic amenities. But buyers aren’t paying extra for technology that would otherwise cost $30,000, according to the homebuilder, because the project was subsidized by a $6.65 million U.S. Department of Energy grant.
The homes have other energy efficiency features such as spray foam insulation under the roof to help cool the attic and the living space below. The houses are essentially “like a Yeti cooler,” as one official with SunPower, the company that provided their solar and battery-storage systems, told me. That’s life changing in this corner of Riverside County where summer days often exceed 100 degrees and utility bills climb painfully high.
After spending a few hours checking out the homes’ energy-smart features and listening to company and government officials talk up their climate-friendliness and resilience, I was almost envious. The people moving into these houses are living in a world that, for now, remains a distant reality for most Californians for whom a fossil fuel-free home is still very much a pipe dream. And it highlighted how much work there is yet to do by state officials to ensure all Californians start to benefit from home electrification as that need becomes increasingly obvious in a world altered by climate change.
California has 14 million homes and builds only about 110,000 new housing units a year. So even if all new homes are built with at least one electric heat pump, as the Energy Commission expects, that would account for only about 8% of all homes by 2030, 14% by 2040, and 20% by 2050. That’s not anywhere near fast enough to slash climate-warming emissions, which means that most of this transition will have to happen by replacing appliances in existing homes.
The furnaces, stoves, clothes dryers and water heaters in our homes and businesses may not seem like big polluters individually, but they all add up to a lot. Buildings are one of the biggest emissions sources in California, responsible for about 25% of its climate pollution. But California still lacks the kind of straightforward zero-emission targets for buildings that it has already adopted for other major pollution sources like electricity generation and new cars.
While California has some laudable goals, including Gov. Gavin Newsom’s target of installing 6 million heat pumps by 2030, state officials acknowledge that much greater numbers will be needed to put California on track to achieving a carbon-neutral economy by 2045.
Whether we rent or own or have a new or historic home, everyone should be able to live in an efficient, non-polluting, and climate-ready dwelling even if it wasn’t purpose-built for an all-electric world like the new construction in Menifee. None of us should have to wait decades for that to be our reality too.
