Best Practices and Insights to Expand Clean Energy Access and Adoption
…follow low-emissions practices and are resilient and inclusive. It draws on international evidence, including workshop discussions, IEA analysis and a wide range of global case studies, to identify key impacts and lessons learned from evidence and practice. It highlights how behaviour change is most effective when supported by coherent policy frameworks, targeted measures addressing affordability and structural changes across sectors such as buildings, transport and appliances. By identifying good practices and practical insights, the report provides guidance to support policymakers design inclusive strategies that enable sustainable lifestyles and ensure the benefits of the energy transition are shared by all.

The Implications of Oil and Gas Field Decline Rates
…evolution of oil and natural gas demand, with less consideration given to how the supply picture could develop. However, understanding decline rates – the annual rate at which production declines from existing oil and gas fields – is crucial for assessing the outlook for oil and gas supply and, by extension, for market balances.The International Energy Agency (IEA) has long examined this issue, and a detailed understanding of decline rates is at the heart of IEA modelling and analysis, underpinning the insights provided by the scenarios in the World Energy Outlook.This new report – based on analysis of the production records of…

Global Critical Minerals Outlook 2025
…and investment trends, along with their implications for critical minerals security. As in last year’s Outlook, it provides a snapshot of recent industry developments from 2024 and early 2025 and offers medium- and long-term projections for the supply and demand of key energy minerals, taking into account the latest policy and technology developments.The 2025 Outlook also explores key techno-economic issues such as policy mechanisms to support diversification; mineral supply chains for emerging battery technologies; recent innovations in mining, refining and recycling; and a broader view on strategic minerals for applications beyond the energy sector. As a new chapter, the report also…

Businesses see competitive value of energy efficiency, but smaller firms struggle to access solutions
…position in global markets. Yet not all firms have the same capacity to quickly improve their energy efficiency.New analysis of the 2025 IEA Industrial Competitiveness Survey – which covered 1 000 companies across 14 countries – shows that business leaders view energy efficiency as closely linked to their competitive performance. But the survey also highlights a persistent divide: while large companies are often well positioned to capture these benefits, many that are small and medium-sized face barriers that limit their ability to invest in efficiency and compete on the same terms. Energy efficiency drives competitiveness across all sectors, with select industries…

Germany 2025
…Review was prepared in partnership between the Government of Germany and the IEA. It draws on the IEA's extensive knowledge and the inputs of expert peers from IEA Member countries to assess Germany’s most pressing energy sector challenges and provide recommendations on how to address them, backed by international best practices. The report also highlights areas where Germany’s leadership can serve as an example in promoting secure clean energy transitions. It also promotes the exchange of best practices among countries to foster learning, build consensus and strengthen political will for a sustainable and affordable clean energy future.

Multiple Benefits of Energy Efficiency
As energy efficiency continues to gain attention as a key resource for economic and social development across all economies, understanding its real value is increasingly important. The multiple benefits approach seeks to expand the perspective of energy efficiency beyond the traditional measure of energy savings by identifying and measuring its impacts in full bloom.

Solar PV
…is added annually through the end of this decade. Even so, low costs, faster permitting and broad social acceptance are set to continue to drive the accelerating adoption of solar PV. As a result, capacity is set to more than double between 2025 and 2030 compared with the 2019 to 2024 period.
A growing share of variable renewable sources such as solar also comes with challenges. Curtailment levels and instances of negative electricity prices have been increasing in many markets. A rapid increase in power system flexibility and grid investment is necessary to integrate future growth securely and cost-effectively.

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

Outlook for Biogas and Biomethane
…Biogases play an important and growing role in energy systems. Produced locally using organic waste, biogas and biomethane can contribute to energy security, waste management, emissions reductions and agricultural development.In recent years, demand for biomethane – also known as “renewable natural gas” – has grown rapidly in many countries, supported by dozens of new policies. As a low-emissions substitute for natural gas, the use of biomethane has been targeted across a wide range of sectors, including power, industry, transport and buildings. This report presents a first-of-its-kind global geographical analysis of the untapped potential of biogas and biomethane…
