Delivering Sustainable Fuels
Pathways to 2035 Sustainable fuels – including liquid biofuels, biogases, low-emissions hydrogen and hydrogen-based fuels – offer multiple benefits for the energy sector. They complement electrification and energy efficiency in energy transitions, and are particularly important for sectors that continue to be reliant on fuel-based solutions such as aviation, shipping, and parts of road transport and industry. Sustainable fuels can also enhance energy security, strengthen environmental sustainability and stimulate economic development, particularly in rural areas.If fully legislated and implemented, current and proposed national and international policies would put the use of sustainable liquid and gaseous fuels on a…

Competitiveness
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores competitiveness. Why is energy efficiency important for competitiveness? Increasing energy efficiency can improve competitiveness at both the firm level – by reducing costs, improving operations and increasing product value – and at the country level, by reducing the amount of energy required to produce economic output. Key facts Today the world’s industries produce nearly 20% more value added with a given amount of energy, compared with two decades ago. In the industrial sector, energy management can lead to more than 10% in annual energy cost savings within…

Pledges to Progress 2025
An assessment of transparency of the oil and gas industry’s emissions reduction efforts At COP28, more than 50 of the world’s leading oil and gas companies launched the Oil and Gas Decarbonization Charter (OGDC), laying out a series of ambitions to achieve net zero operational emissions by 2050. As global methane and flaring emissions continue to rise, these ambitions are more important than ever to reduce energy waste and mitigate the harmful consequences of climate change.To support accountability and transparency, the International Energy Agency (IEA), the United Nations Environment Programme (UNEP) International Methane Emissions Observatory (IMEO) and…

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…

Financing Electricity Access in Africa
Access to electricity is a cornerstone for economic development, poverty reduction and social equity. However, almost 600 million people in Africa lack access to electricity today, with progress falling far behind targets set by both African governments and the international community. Reaching universal electricity access will require a rapid scale-up of investment and financing to USD 15 billion per year, enabling the expansion of generation capacity, grid networks and decentralised solutions while ensuring that progress remains inclusive and sustainable.In a new flagship report, Financing Electricity Access in Africa, the International Energy Agency (IEA) undertakes its authoritative energy analysis…

National Climate Resilience Assessment for Algeria
Algeria’s energy system already faces significant disruption due to extreme weather events. Critical infrastructure has been impacted in recent years by flash floods, drought-induced wildfires and heatwaves. With the climate projected to warm more rapidly than the global average, these risks are likely to intensify. Proactive measures to enhance the resilience of Algeria’s energy system could offer substantial benefits.Algeria has experienced significant warming, averaging 0.49 °C per decade from 2000 to 2023 and exceeding the global average of 0.37 °C per decade. Temperatures are expected to rise further, reaching up to 5.6 °C above pre‑industrial levels…
