The news: Heat pumps, which use electricity to both heat and cool homes, are now just as common in low-income households in the US as they are in wealthier ones. This bucks the trend among consumer climate technologies, many of which are much more likely to be adopted by the wealthy.
Why it matters: Heating buildings is a huge climate problem—roughly 10% of global emissions come from our efforts to keep our indoor spaces comfortable. But while governments are eager for people to adopt new appliances that could replace systems that burn fossil fuels, historically, such changes haven’t been distributed equally. Heat pumps, at least in the US, seem to be different. That’s good news.
The big picture: The number of households that rely on heat pumps is still small, and there’s no guarantee that they will continue to be adopted at equal rates by households with different incomes.
