What Next for the Global Car Industry
An Energy Technology Perspectives Special Report The global car industry has operated under relatively stable conditions for decades. The world’s largest car manufacturers are based in the European Union, Korea, Japan and the United States, and – more recently – in China, and the car industry is a major contributor to the economy in these countries. The strength of many of these car makers is built on decades at the forefront of technological innovation around the internal combustion engine (ICE), as well as highly integrated and optimised supply chains that allow for vehicles and their components to be produced at low…

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
Between October 2023 and March 2025, the IEA implemented the “Accelerating Renewable Energy Permitting” (ARPE) action. The goal of ARPE was to support five EU Member states – Finland, Ireland, Lithuania, the Netherlands, and the Slovak Republic (Focus countries) – in developing and implementing policy and regulatory measures aimed at reaching their renewable energy targets, notably through accelerating permitting of renewable energy projects.In support of this objective, the IEA organised and facilitated five workshops focused on the following topics:streamlining administrative proceduresaccelerating offshore wind deploymentfacilitating spatial planning for renewable energy deploymentensuring public engagement and acceptance, and afinal workshop summarizing the project…

World Energy Outlook 2025
The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi…

Vehicle-to-grid technology
…variable renewable generation, maintaining the balance between electricity supply and demand becomes increasingly complex and costly.EVs offer substantial demand side flexibility via smart charging. Beyond this, vehicle‑to‑grid (V2G) technology enables EVs to provide grid‑stabilisation services through bidirectional power flow. Realising this potential, however, requires widespread deployment of V2G‑compatible vehicles and chargers, multiparty interoperable communication protocols, as well as supportive testing regimes, regulatory frameworks, and financial incentives.Through controlled charging and discharging, EV batteries become flexible assets for energy storage rather than mere loads to the grid. There are varying degrees of flexibility. With unidirectional smart charging (V1G), the charging…

Renewables in District Energy
…around 600 million people worldwide, but many systems remain heavily dependent on fossil fuels, exposing consumers and utilities to price volatility, supply risks and high emissions.The report provides a global overview of district energy systems, their fuel mixes, market conditions, governance models and affordability implications. It explores the growing opportunities offered by renewable and recovered heat sources, including bioenergy, geothermal, solar thermal, waste heat, large-scale heat pumps and thermal energy storage. It also sets out policy priorities for three types of markets: established systems with high renewable shares, fossil fuel-intensive networks, and emerging or untapped district energy markets.
