World Energy Investment 2025 United States
Energy investment policies in the United States reflect its prioritisation of energy security Energy investment in the United States reflects its prioritisation of energy security, with a subsequent strategic push to establish a presence in emerging value chains and to supply international markets. Since becoming a net energy exporter in 2019, a remarkable turnaround from its high previous reliance on imports, the country has continued to expand its global energy role. In 2024 it was the world’s largest producer of oil and gas (20% of global output), as well as a major investor (25% of total investment). This growth…

Ukraine’s Energy Security
A pre-winter assessment As Ukraine enters its fourth winter of war, ensuring that residents retain reliable access to heat and power is of the utmost importance. While Ukraine made strong strides in rebuilding and strengthening the resilience of its energy system this past spring and summer, the situation remains fragile, and the risk of huge disruptions and widespread destabilisation remains – particularly as Russia expands the scope and sophistication of its attacks.This analysis builds on the IEA’s September 2024 report, Ukraine’s Energy Security and the Coming Winter. It provides an update on the latest developments through October…

Germany
Germany’s Climate Law sets out the framework for reaching net zero emissions by 2045. In order to achieve the ambitious Energiewende by 2030, 80% of all electricity supply will need to come from renewable energy sources (and 100% by 2035) and coal is to be completely phased out. Germany has been an early leader in offshore wind and solar PV and phased out nuclear power in 2023. Major legislative reforms in renewable energy planning and siting support targets of 100-110 GW of onshore wind, 30 GW offshore wind and 200 GW solar, alongside investments in 10 GW of…

Best Practices and Insights to Expand Clean Energy Access and Adoption
This report was commissioned by the European Commission to serve as a technical repository of analysis and evidence-based practices in support of the Campaign on Sustainable Lifestyles, Fairness and Access to Clean Energy Technologies. The analysis presented draws on discussions and research shared during the Widening Participation in Clean Energy workshop held in Brussels, contributions presented at the official all-member meetings of the Campaign on Sustainable Lifestyles, and the IEA’s analytical work in areas such as people-centred clean energy transitions, affordability, energy efficiency and clean energy access.This work is organised into three chapters, each corresponding…

Breakthrough Agenda Report 2025 Power
State of the transition Emissions Global emissions from electricity generation rose by 1.2% in 2024 to around 13.9 Gt of CO2, following an increase of 1.6% in 2023.The global emissions intensity of electricity generation is on a contracting trend, with a record 3% reduction in 2024 compared to 1% in 2023. This improvement reflects the rapid growth in renewable energy and nuclear electricity production relative to rising demand. Cost On an levelised cost of electricity (LCOE) basis, renewables remained the most cost-competitive option for new electricity generation in 2024.Onshore wind remained the most affordable…

Renewables in District Energy
This report examines how renewables can play a larger role in district energy systems, helping to deliver cleaner, more secure and more efficient heating and cooling. District energy networks already supply heat to 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…
