| Judging by the surging sales of green technology, U.S. households appear to be on the verge of a low-carbon future. Millions of Americans are buying electric vehicles, heat pumps and induction ranges. But those numbers belie a starkly different present. Just about 3 percent of Americans, for example, reported owning an induction stove in 2022. That's close to the share of the U.S. population that owned a cellphone in the late 1980s, a few years after the first models came out. It took more than two decades for wireless technology to eclipse home landlines. Time is tighter for the climate. To meet net-zero emissions targets, and avoid the worst effects of warming, most households will need to embrace a new suite of low-carbon technologies by 2050, says the electrification nonprofit Rewiring America. To make it happen, they're betting on the "S-curve." Virtually every major technology over the past two centuries has followed the same trajectory, though the exact nature of the curve or slope change varies by product. Take a look below. |
