Global Energy Review 2026 Technology: Heat pumps
Global heat pump sales fell by about 2% in 2025. Sales in China and Japan were largely flat, while Europe saw a strong return of demand. Sales in the United States declined.In China, heat pump sales stayed broadly stable. Reversible air conditioners (used as primary heating equipment) make up about half the Chinese heat pump market, and while record-breaking sales of air conditioners supported strong demand in the first half the year, they fell sharply in the second half. Sales of air-to-water and hot water heat pumps, which make up the remainder of the market, remained…

China
China’s growing energy needs are increasingly met by renewables, natural gas and electricity. The scale of China’s future electricity demand and the challenge of decarbonising the power supply help explain why global investment in electricity overtook that of oil and gas for the first time in 2016, and why electricity security is moving firmly up the policy agenda. That said, cost reductions for renewables are not sufficient on their own to secure efficient decarbonisation or reliable supply.
Between 2019 and 2024, China will account for 40% of global renewable capacity expansion, driven by improved system integration, lower curtailment…- Overview

Integrating Distributed Energy Resources in China
Lessons from international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to…

Ramping up Heat Pumps in Moldova: A Roadmap
Buildings account for more than half of Moldova’s final energy consumption, with three-quarters of that used for space and water heating. At the same time, Moldova lacks domestic hydrocarbon resources and imports more than 80% of its primary energy. Heat pump technology offers Moldova an effective means of accelerating the transition in building heating.The recent expansion of Moldova’s solar and wind capacity also means that heat pumps can now play a greater role in cutting greenhouse gas emissions and lowering local air pollution. Finally, Moldovan’s 2024 referendum, endorsing the goal of European Union membership, underscores…

Heat Pump Taxonomy
A common framework for heat pumps classification and data Heat pumps are a cornerstone technology for achieving secure, affordable and sustainable heating. They have become one of the most common heating technologies and have the potential to impact significantly future trends for energy consumption in buildings and beyond.Tracking and analysing the pace of heat pump deployment compared to that of conventional heating technologies is essential for understanding future needs with regards to energy demand, investments in electricity infrastructure and fuel supply.Despite their growing importance, data on heat pump installations, as well as on their performance and cost, remain…

China’s Official Energy Finance in Emerging and Developing Economies
Evolving institutions, instruments and implications for clean energy transitions Global energy investment exceeded USD 3.3 trillion in 2025, but capital flows remain uneven. Emerging market and developing economies (EMDE) outside China attracted just 27% of total energy investment and 18% of clean energy spending, despite accounting for nearly two-thirds of the global population and the bulk of future demand. Addressing this imbalance requires mobilising more capital from diverse sources into EMDE energy systems.China continues to play a central role in global energy investment flows because of its large domestic investments and its large external capital spending on energy. Since…

Investment in next-generation geothermal is surging. Policies are key to further growth
Next-generation geothermal readies for take-off Next-generation geothermal is seeing a burst of financing, innovation and new supply agreements Geothermal energy harnesses naturally occurring heat found beneath the Earth’s surface to provide heating and cooling, electricity and energy storage. As global electricity demand rises and power systems place a growing premium on firm supply, geothermal energy’s ability to provide an around-the-clock, low-emissions source of power is attracting renewed attention. However, easy-to-access conventional geothermal resources are relatively rare and mostly confined to a small number of shallow geothermal hotspots globally, accounting for…

Hydroelectricity
Hydropower is the largest source of renewable 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…

Renewables for Industry
Electrification of low-temperature heat and steam Industry is responsible for 30% of global energy consumption, most of which is supplied by fossil fuels. The focus of industrial decarbonisation has largely been on the steel and cement sectors, but significant potential also exists in less energy-intensive sectors such as food and beverages, textiles, chemicals, paper, and other manufacturing activities. These sectors offer some of the most immediate and cost-effective opportunities for industrial decarbonisation and diversification of energy sources. Commercially available electric technologies – including heat pumps, electric boilers and resistance heaters – can meet most heat demand in these subsectors…

World Energy Investment 2025 China
Record-breaking renewables investment in China continues, advancing in tandem with the expansion of grid and storage for renewables while keeping coal in the mix In the ten years since the signing of the Paris Agreement and five years since the announcement of the dual carbon goals, China has seen a precipitous rise in clean energy investment, particularly in renewables. In 2024 China’s clean energy investment was more than USD 625 billion, almost doubling since 2015. China also achieved its 2030 wind and solar capacity target in 2024, six years ahead of schedule. While renewable installations are set to continue, investment…
