Slow adoption of smart thermostats in the US misses big potential energy savings: S&P | Utility Dive

Rising energy prices and the potential for extended heat waves will push more homeowners to install smart thermostats this year, but overall sluggish adoption leaves “a substantive energy conservation opportunity untapped at the macro level,” according to Kagan, the media research unit of S&P Global Market Intelligence.

Analysts say 19.6 million smart thermostats were installed in the U.S. at the end of last year, helping the country to consume 1.4% less energy on space heating and cooling than it otherwise would have. Installed smart thermostats are expected to reach 38.3 million in 2026, Kagan predicted, potentially saving the U.S. 15.5 TWh of electricity.

The American Council for an Energy-Efficient Economy in 2018 pegged the potential savings of HVAC-connected smart thermostats at up to 10%.
