Energy Efficiency 2025
Market Report Energy Efficiency 2025 is the IEA’s primary annual analysis on global energy efficiency developments, showing recent trends in energy intensity and demand, investment, employment and policy. The report provides sector-specific analysis on industry, buildings, appliances and transport and explores system-wide themes such as emissions reductions, energy security, affordability and competitiveness. This report is launched in parallel with an update to the IEA Energy Efficiency Progress Tracker, which can be accessed through the IEA website.

World Energy Outlook 2025 Setting the scene
…needs. Electricity use expanded rapidly across a range of sectors. Deployment of renewable power generation again broke records in 2024, meeting more than 70% of the increase in electricity demand. Consumption of each of the fossil fuels rose. Global energy-related carbon dioxide (CO2) emissions reached another all-time high. The energy sector faces many uncertainties. The global economy is projected to grow at an average rate of 3% in the 2024-2030 period, but changes in the global policy environment and trade outlook could lead to different outcomes. In parallel, a drift towards greater fragmentation and increased geopolitical rivalry…

Chile
Chile’s energy policy has evolved dynamically in recent years. In response to changes in the domestic and international environment, significant institutional and policy reforms as well as major infrastructure projects have been carried out. In 2022, Chile’s Ministry of Energy published an update to its the Long-Term Energy Policy (PELP, first published in 2015), which re-emphasises the pledge to net-zero, laying out a clear decarbonisation pathway that addresses all sectors of the national economy.
Based on its excellent renewable energy resources, Chile has taken a globally leading role in clean energy, and emerged as a…- Overview

Renewables 2025 Renewable heat
…targets and carbon pricing.In the buildings sector, three-quarters of renewable heat developments in the past six years took place in China, the European Union and the United States. Heat pump deployment has played a major role in all these markets, translating into rising consumption of both electricity and ambient heat for space and water heating. Large additional contributions also came from electric heating equipment and solar thermal and geothermal developments in China. If fossil fuel use is not contained, the heat sector alone in 2025-2030 could consume more than one-fifth of the remaining carbon budget for…

Korea 2025
Energy Policy Review Government action plays a pivotal role in ensuring secure and sustainable energy transitions. Energy policy is critical not just for the energy sector but also for meeting environmental, economic and social goals. Governments need to respond to their country’s specific needs, adapt to regional contexts and help address global challenges. In this context, the International Energy Agency (IEA) conducts Energy Policy Reviews to support governments in developing more impactful energy and climate policies.This Energy Policy Review was prepared in partnership between the Government of Korea and the IEA. It draws on the IEA’s extensive…

Energy Efficiency 2024 Executive summary
…including switching to EVs. The reduction in natural gas demand related to efficiency, which would be more than Europe’s total natural gas use in 2024, comes largely from measures such as insulating buildings and the electrification of heating.Accelerating energy efficiency improvements can deliver over a third of all carbon dioxide (CO2) emission reductions between now and 2030 in a pathway aligned with reaching net zero emissions by 2050. This involves speeding up electrification and improvements in technical efficiency. From 2010 to 2022, improvements in energy intensity contributed to a cumulative reduction in global CO₂ emissions of almost 7 gigatonnes…

India
Energy demand in India is growing rapidly with major implications for the global energy market. The Government of India has made remarkable progress in providing access to electricity and clean cooking while implementing a range of energy market reforms and integrating a high share of renewable energy sources into the grid. India, with a population of 1.36 billion and a fast growing economy, has seen its energy demand increasing rapidly as the country continues to urbanize and the manufacturing sector develops. This growing demand is met through various energy sources, with coal set to remain the largest source of…
