The rate of global energy efficiency improvement in 2022 was double the average of the previous five years, propelled by rising sales of more efficient technologies like heat pumps. The following trendline examines these and other trends and developments in energy efficiency.

Included in this Trendline:

• Energy efficiency ‘crucial’ to decarbonization, even with low levels of building electrification: ACEEE
• California greenlights $4.3B funding for energy efficiency
• US residential heat pump sales pass gas furnaces for first time as interest in efficiency tech surges
