Global Energy Review 2026 Electricity supply
The increase in low-emissions power generation in 2025 outstripped total electricity supply growth Global electricity generation increased by over 850 TWh in 2025, with renewables accounting for the vast majority of growth. Together, generation from renewables and nuclear power rose by more than the total global increase in generation. In contrast, generation from fossil fuels declined: a modest rise in natural gas-fired generation was outweighed by a decline for coal. Global coal-fired generation fell by around 0.5%, marking the first decrease since the Covid‑driven drop in 2020 and the first decline outside of a period of…

Electricity Mid-Year Update 2025 Emissions: Power generation CO2 emissions are plateauing
Global emissions from electricity generation rose by 1.2% in 2024, following an increase of 1.6% in 2023. Last year was even hotter than in 2023 – making it the warmest year on record – with the heat waves boosting electricity demand for cooling. Nonetheless, growth in power sector emissions showed signs of slowing down as rapid deployment of renewables constrained increases in fossil-fired generation. As this trend continues, we expect 2025 emissions to plateau and remain relatively unchanged. In 2026, we forecast a slight decline of less than 1%, as the increase in low-emissions generation depresses fossil-fired…

World Energy Investment 2025 European Union
Energy investment in the European Union has shifted over the past decade to low-emissions generation. Grid investment is key to EU price convergence and market stability In the past decade, the European Union (EU) has increased its commitment to clean energy, with investment reaching almost USD 390 billion in 2025. Investment in low-emissions electricity was driven by the global energy crisis that followed Russia’s full-scale invasion of Ukraine in 2022, subsequent favourable policy incentives and the declining cost of renewable technologies. In 2024 renewables generated 50% of electricity used in the EU, while fossil fuels accounted…

Gaining an Edge Opportunities in efficiency markets
As market demand grows, the manufacturing of energy efficiency technologies represents a new opportunity Facing volatile energy prices, rising energy security risks and stricter regulations, all sectors are turning to energy efficiency technologies to reduce consumption and manage these growing challenges. At the same time, governments around the world committed at COP28 in Dubai in 2023 to work collectively to double the global average annual rate of energy efficiency improvements.These dynamics have triggered a strong increase in demand for energy efficiency technologies. For example, the market for electric vehicles (EVs) and batteries has grown nearly six-fold from 2020…

Energy Efficiency Policy Toolkit Transport
Introduction Private cars and vans were responsible for more than 25% of global oil use and around 10% of energy-related CO2-emissions in 2023. Doubling global annual energy intensity improvement by 2030 would require the efficiency of cars to improve by 5% each year. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal.Regulations such as fuel economy standards and heavy-duty vehicle standards encourage manufacturers to introduce more efficient vehicles, thereby significantly reducing greenhouse gas emissions. Countries with regulations and/or efficiency-based purchase incentives in place improve efficiency…

The Implications of Oil and Gas Field Decline Rates Executive summary
Discussions on the future of oil and gas often overemphasise demand drivers and underappreciate supply drivers Debate over the future of oil and natural gas tends to focus on the outlook for demand, with much less consideration given to how the supply picture could develop. This asymmetry is misplaced and a thorough understanding of the rate at which production from existing oil and gas fields declines over time is more important than ever. The International Energy Agency (IEA) has long examined this issue. Decline rates – the annual rate at which production declines from an existing oil or gas field – underpin…

Household Energy Affordability Executive summary
Household energy affordability continues to be a key priority for governments as energy bills remain elevated Household energy bills globally have come down from the peaks seen during the global energy crisis in 2022, but on average they were still around 4% higher in real terms in 2024 than they were in 2019. Household energy bills soared in many parts of the world as a result of the Covid-19 pandemic and Russia’s full-scale invasion of Ukraine in 2022, which introduced a period of extreme volatility and a sharp run-up in prices. At the peak of the…
