Multiple Benefits of Energy Efficiency for Business
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone. However, the value of energy efficiency extends beyond energy savings.This report builds on the IEA’s work on the multiple benefits of energy efficiency and focusses on how these gains materialise in businesses. Key benefits range from productivity and product quality improvements to brand image or health benefits for employees and…

Energy and AI
Energy and AI The development and uptake of artificial intelligence (AI) has accelerated in recent years – elevating the question of what widespread deployment of the technology will mean for the energy sector. There is no AI without energy – specifically electricity for data centres. At the same time, AI could transform how the energy industry operates if it is adopted at scale. However, until now, policy makers and other stakeholders have often lacked the tools to analyse both sides of this issue due to a lack of comprehensive data. This report from the International Energy Agency (IEA) aims to fill this…

Country
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…

The Implications of Oil and Gas Field Decline Rates
Much attention today focuses on uncertainties affecting the future 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…

State of Energy Policy 2026 Energy efficiency and fuel switching regulations
More than 130 countries have energy efficiency or fuel switching regulations in place, but some were revised, delayed or withdrawn in 2025 Energy use has become more efficient around the world since 2000. Global energy intensity has improved by around 30% over the past 25 years, meaning the world uses about 30% less energy per unit of economic output today than it did in 2000, with differentiated trends by key end uses: passenger cars and air conditioners have notably seen efficiency improvements for new sales of 30% and 45%, respectively since 2005. However, the pace of improvement has slowed over…

Global electric car sales continue to break records as affordability improves
Despite recent economic headwinds that have put pressure on the auto sector, global sales of electric cars have continued to break records as electric models become increasingly affordable. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%. Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020.
In 2025, sales of electric cars are expected to surpass 20 million, accounting for over…
