…2021 to 2030 thanks to a swift acceleration of efficiency improvements and widespread adoption of heat pumps.
Global heat pump sales continue double-digit growth
Global sales of heat pumps grew by 11% in 2022, according to the latest IEA analysis, marking a second year of double-digit growth for the central technology in the world’s transition to secure and sustainable heating. Increased policy support and incentives for heat pumps in light of high natural gas prices and efforts to reduce greenhouse gas emissions were key drivers behind the strong uptake.
In Europe, heat pumps enjoyed a record year…

Wind has significant potential to boost growth in global renewable capacity
Electricity generation from renewables is expected to increase by 60% through 2030 – rising from 9 900 terawatt-hours (TWh) in 2024 to 16 200 TWh by the end of the decade. Wind accounts for almost a third of growth, second only to solar PV, which accounts for 60%.
Although wind power continues to face supply chain issues, rising costs and permitting delays today, global capacity is still expected to nearly double to over 2 000 gigawatts (GW) by 2030 as both advanced and developing economies tackle these barriers.

Grid investments
…On average, energy efficiency costs less than half the amount it would cost to build new generation capacity and grid infrastructure, per unit of energy.Energy efficiency measures can typically be deployed in under a year, while generation and transmission projects require between one and seven years to build on average, depending on technology, or over a decade for nuclear. Key analysis IEA analysis of nine major regions shows that increasing electricity generation and grid capacity by one terawatt-hour (TWh), will require investments of USD 30 to 110 million in emerging economies and USD 75 to 150 million in advanced economies. In…

Country
Brazil
Brazil’s energy policies measure up well against the world’s most urgent energy challenges. Access to electricity across the country is almost universal and renewables meet almost 45% of primary energy demand, making Brazil’s energy sector one of the least carbon-intensive in the world. Total primary energy demand has doubled in Brazil since 1990, led by strong growth in electricity consumption and in demand for transport fuels on the back of robust economic growth and a burgeoning middle class.
Large hydropower plants account for around 80% of domestic electricity generation, making the Brazilian electricity mix one of…- Overview

Energy Transition Review for Enhancing Co-operation
The Philippines’ power sector This report is part of ongoing IEA collaboration with Asia Zero Emission Community (AZEC) partners to better understand the particular challenges these partners face in their energy transition and to provide a platform for co-operation among the AZEC partners. The report seeks to build a shared understanding of the challenges and opportunities facing the Philippine power sector, and to identify practical pathways that can help to strengthen its energy security, improve affordability and enable the country to achieve its long-term clean energy goals.This review has been prepared in collaboration with the Department of Energy…

Global Energy and Climate Model Announced Pledges Scenario (APS)
…Scenario (APS), introduced in 2021, illustrates the extent to which announced ambitions and targets can deliver the emissions reductions needed to achieve net zero emissions by 2050. In the WEO-2024, the APS includes all recent major national announcements as of the end of August 2024, both 2030 targets and longer-term net zero or carbon neutrality pledges, regardless of whether these announcements have been anchored in legislation or in updated Nationally Determined Contributions. In the APS, countries implement their national targets in full and on time. The outlook for exporters of fossil fuels and low-emissions fuels, such as hydrogen…

Luxembourg 2026 Executive summary
Luxembourg has established ambitious climate and energy objectives, but more targeted policy measures are needed to meet them. Luxembourg’s climate and energy goals are aligned with the European Union (EU) targets for a 55% reduction in greenhouse gas (GHG) emissions by 2030 and a 90% reduction by 2040, and it has legally enshrined net zero emissions by 2050. Despite rapid population and economic growth, energy-related emissions have already fallen by 40% since 2005, reflecting the success of early measures. Public support for climate action is also robust, providing a strong foundation for the next phase of the transition…

Financing the Modernisation of Power Systems Beyond Coal Executive summary
The role of coal in power systems is evolving This report assesses the potential applications, limitations and relevance of transition credits in Southeast Asia. Coal is the largest source of power generation worldwide and the largest source of energy-related carbon dioxide emissions. All Southeast Asian countries with coal in their power generation mix have adopted commitments to reduce coal-fired generation or emissions targets that imply a significant decline in coal consumption in the coming decades. To meet these targets, the International Energy Agency (IEA) has long emphasised that a range of strategies can be deployed to reduce coal…

Global Energy Review 2026 Technology: Battery storage
Battery storage is the fastest growing power technology today. In 2025, 108 GW of new battery storage capacity was deployed worldwide, 40% more than in 2024. Installed capacity is now eleven times higher than in 2021. Lithium‑iron phosphate (LFP) batteries now account for around 90% of deployments; while less energy‑dense than rival chemistries commonly used in EVs, LFP batteries are typically cheaper and better suited to more frequent cycling. Just five years ago, the market share of LFP batteries in deployments was well below 50%. Around 80% of new battery capacity in 2025 was utility‑scale. The remainder was behind-the…

The State of Energy Innovation 2026 Executive summary
Successful energy innovations can have outsize economic and social outcomes, impacting industrial competitiveness, trade, environmental health, infrastructure investment and security. The second edition of the State of Energy Innovation turns the spotlight on the technologies, policies and funders at the forefront of this process. Today, the global markets for energy technologies such as batteries, transformers, turbines, motors and heat exchangers are worth trillions of dollars. With spending on energy representing as much as 10% of global GDP, innovation that reduces energy supply costs can transform a country’s comparative advantage. As a result, the energy sector is innovation-intensive: one…
