Heating
…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.
The IEA’s Outlooks for gas markets and investment report estimates that gas demand in buildings…

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…

Natural Gas
…markets, which have been tight and volatile for several years, are set to undergo major changes by the end of this decade. The unfolding coming wave of liquefied natural gas (LNG) production capacity is set to rebalance the global gas market, enhance energy supply security and improve the affordability of natural gas.
About 300 billion cubic metres (bcm) per year of LNG export capacity – a record – is set to be added by 2030, primarily supported by liquefaction capacity additions in the United States and Qatar. This expansion could translate to a net LNG supply increase of 250 bcm a year…

Hydroelectricity
…energy today, but that could change soon
Hydro is currently the third largest source of power generation worldwide after coal and natural gas. In 2024, it generated around 4 500 terawatt-hours of electricity, or 14% of the global total.
More than 150 gigawatts (GW) of new hydro capacity is set to come online by the end of the decade, mostly in emerging and developing economies. As a result, electricity generation from hydropower is expected to increase by 7% between 2025 and 2030. However, its share in global electricity generation is poised to decrease slightly by 2030 as other energy…
