Heating
…is a significant driver of global energy demand, both in buildings and in industry, and is an important component of energy expenditure for households, especially in colder climates. Many households use natural gas to warm their homes, provide hot water and to cook. Residential and commercial gas demand dropped by more than 15% in 2022 compared to the year before. While 40% of the decline in residential and commercial demand in Europe can be attributed to weather-related factors (reduced space heating needs due to a mild winter), a substantial part was achieved through various gas-saving measures.

Standards and labelling can lift the average rate of energy efficiency improvement by two to three times
Based on global evidence from countries with Energy efficiency standards and labelling (EES&L) programmes, the average energy efficiency of new major appliances in these countries can increase two to three times the underlying rate of technology improvement. This can result in average energy reductions of 10-30% over 15 to 20 years in the stock of most regulated products across all countries.
In leading countries with strong regulations and long-running programmes which are regularly updated, the contribution could be much higher…

Stronger efficiency is the first and best policy to bring down energy bills
Variations in energy efficiency exist both within and among countries. For example, in some European countries with similar climates it can take twice as much energy to heat the same floor area or within one country the energy consumed between the most efficient and least efficient homes for a given size can vary by a factor of up to three.

Energy Efficiency
…Preliminary estimates indicate that several key economies, such as India and China, are showing some indications of stronger progress compared with their average since 2019.
The rate of global improvement in energy efficiency has been largely lacklustre since 2019, averaging around 1.3% annually. That’s down significantly from the average of around 2% per year between 2010 and 2019 – and well short of the goal of 4% by 2030 that was set at COP28 in Dubai in 2023, where nearly 200 governments agreed to work together to double the global average annual rate of energy efficiency improvements by 2030.

Heat Pumps
…the central technology in the global transition to secure and sustainable heating. The Future of Heat Pumps, a special report in the IEA’s World Energy Outlook series, provides an outlook for heat pumps, identifying key opportunities to accelerate their deployment. It also highlights the major barriers and policy solutions, and explores the implications of an accelerated uptake of heat pumps for energy security, consumers’ energy bills, employment and efforts to tackle climate change.
Around 10% of space heating needs globally were met by heat pumps in 2021, but the pace of installation is growing rapidly with sales at record…
