Energy savings
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores energy savings. Why is energy efficiency important for energy savings? Energy efficiency measures reduce the amount of energy required to fuel and grow our economies. In economies where energy demand is set to grow significantly, efficiency also helps improve people’s lives by increasing access to additional energy services. Key facts In the last two decades, efficiency measures have generated over 27 EJ of energy savings in IEA countries alone, equivalent to 20% of total energy demand.The industry (including manufacturing) and services (including commercial buildings) sectors…

Global Hydrogen Review 2026 Policy
A total of USD 41 billion in public funding has been identified in policy updates made since the Global Hydrogen Review 2025 (GHR-25). Nearly two-thirds of this funding is linked to legislation in force and almost 25% has already been disbursed to projects, triggering final investment decisions (FID). As in GHR-25, most of the funding comes from advanced economies and for every dollar going to demand, about 1.5 dollars go to supply.The number of national hydrogen strategies has stabilised at 66 globally, and recent updates have focused either on implementing strategy actions (Brazil, Mauritania, Romania) or revising targets…

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…

Energy and AI in East Asia
This report was commissioned by the Korea Energy Economics Institute and was carried out jointly by the International Energy Agency (IEA) and the Korea Energy Economics Institute. The study has three objectives in the context of East Asia. First is to explore the possibilities presented by AI for the energy sector. Second is to examine the expected increase in electricity demand by data centres, and the impact on grid planning and operation. Third is to provide policy recommendations for embracing the opportunities presented by the application of AI to energy, as well as policies for proactively managing the challenges presented by…

Ramping up Heat Pumps in Moldova: A Roadmap Building the market
This chapter focuses on driving consumer and industrial demand for heat pumps while building a base of manufacturers and installers. It discusses energy pricing, including taxes and levies on electricity and gas, carbon pricing and other types of instruments to encourage the deployment of heat pumps in Moldova. Communication A main barrier identified during stakeholder consultations for this study was a lack of consumer knowledge and experience with heat pumps. This is an issue that should be addressed upfront, as it can result in uncertainty about the operation of heat pumps and spreading of misinformation about their applications or limits…

Global Hydrogen Review 2025 Policies
Highlights Announced public funding for low-emissions hydrogen decreased by nearly two-thirds compared to the Global Hydrogen Review 2024 (GHR-24), to a cumulative USD 38 billion, but a larger share of funds is now making its way to specific projects. Several programmes in the European Union, India, Japan and United Kingdom have progressed to the second phase or beyond, with new calls building on learning from the first phase.Almost 90% of the public funding comes from advanced economies; other policy instruments like land allocation, tax incentives and reduced administrative procedures remain more common among emerging markets. The supply side still receives…
