For example, instead of asking "Tell me about energy trends," try, "Summarize the key findings on renewable energy capacity from the World Energy Outlook 2025."Ask one question at a time: To ensure clarity and focus, ask one question at a time. This helps the agent provide a more precise and helpful response. If the response isn’t what you expected, rephrase or refine your query to better guide the agent.Provide context when needed: If your question relates to a specific section or chapter of the World Energy Outlook 2025, mention it in your prompt.

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.

Grid investments
…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 order to save the same amount of electricity, energy efficiency measures would cost only between USD 10 million and 50 million. A closer look at grid management The deployment of energy efficiency measures typically requires less time than the implementation of most new generation and grid infrastructure. On average, new generation and grid infrastructure can take years to implement, whereas efficiency measures…

Global Energy Review 2025
…demand for electricity rising almost twice as fast as wider energy demand due to higher demand for cooling, rising consumption by industry, the electrification of transport and the growth of data centres and artificial intelligence. Nearly all of the rise in electricity demand was met by low-emissions sources, led by the record-breaking expansion of solar PV capacity, with further growth in other renewables and nuclear power. Gas demand also picked up substantially, while oil and coal consumption increased more slowly than in 2023.CO2 emissions from the energy sector continued to increase in 2024 but at a slower…

…impact of energy efficiency policies on macroeconomic performance still needs to be better understood and systematically measured, studies have highlighted some economic benefits:Growth in economic activityVarious studies have modelled the impact of select energy efficiency policies on economic activity and found a positive correlation. In Canada, an analysis of the country’s policy package at the time found that every USD 1 spent on energy efficiency programmes would generate between USD 4 and USD 7 in GDP between 2017 and 2030. In the United States, a study funded by the Department of Energy estimated that doubling energy productivity could…

Lithium
Outlook for key energy transition minerals This report provides an outlook for demand and supply for key energy minerals including copper, lithium, nickel, cobalt, graphite and rare earth elements. Demand projections encompass both key energy technologies and other uses under different IEA Scenarios. Supply projections are based on a detailed review of all announced projects. They show how today's geographical concentration evolves over time, for both mining and refining and how expected supply compares with primary supply requirements.

…D) budgets. It outlines the methodology and classification system used to collect and structure RD&D data across IEA member countries, ensuring consistency and comparability. The manual is divided into two main sections: fundamentals of RD&D budget reporting and a detailed classification of energy technologies. It defines RD&D in alignment with the OECD Frascati Manual and clarifies the scope of public and private sector reporting. It also provides instructions for completing the IEA questionnaire, covering budgetary stages, metadata reporting, and common issues. The classification system spans nine major technology groups, including energy end uses, fossil fuels, renewables, nuclear…
