Grid investments
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores grid investments. Why is energy efficiency important for grid investments? As we enter the Age of Electricity, global electricity demand is rising rapidly – and so is the demand for the expansion of electricity grids. Energy efficiency can help close the gap between supply and demand, but often at a lower cost, and more quickly, than new generation and grid expansion. Key facts On average, energy efficiency costs less than half the amount it would cost to build new generation capacity and grid infrastructure, per unit of…

Integrating Solar and Wind in Southeast Asia
Status and outlook for secure and efficient strategies Southeast Asia is experiencing one of the fastest electricity demand growths globally, with consumption set to double by 2050. While renewable deployment has accelerated in recent years, the region’s growing reliance on imported fossil-fuels for electricity generation, exposes countries to volatile fuel prices, potential supply disruptions and rising emissions. At the same time, the region possesses vast and diverse renewable resource potential. Variable renewable energy (VRE) - solar and wind - are now among the most cost-competitive generation options and are playing an increasingly important role in the region’s power…

Gas Market Lessons from the 2022-2023 Energy Crisis
The 2022-2023 energy crisis tested the resilience of the global gas and LNG markets with the most severe gas supply shock in history. During the crisis, natural gas-importing markets around the world felt the pressures of record-high gas prices, including the scale-back in access to energy, the impediment to economic activity and the extra burden on government budgets. Market responses varied but governments were quick to react as the challenges of security of supply became apparent. Post-crisis, markets must continue to adapt as the effects of the crisis continue to influence security of gas supply…

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…

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…

Ensuring a Strong Labour Dimension for Just and Inclusive Energy Transitions
IEA Clean Energy Labour Council Workers play a critical role in the global energy system, providing key services across many areas of the energy sector. To give a greater voice to the labour perspective in energy and climate policy discussions, the IEA Executive Director, Dr. Fatih Birol, convened the Clean Energy Labour Council in 2022. The Labour Council brings together representatives of the world’s most important national trade unions and trade union confederations, as well as prominent thinkers on the topic, to foster engagement between the IEA, energy policy makers, and the labour movement.The IEA Clean Energy Labour…

Energy and AI in East Asia
This report was commissioned by the Korea Energy Economics Institute and was carried out jointly by the International Energy Agency (IEA) and the Korea Energy Economics Institute. The study has three objectives in the context of East Asia. First is to explore the possibilities presented by AI for the energy sector. Second is to examine the expected increase in electricity demand by data centres, and the impact on grid planning and operation. Third is to provide policy recommendations for embracing the opportunities presented by the application of AI to energy, as well as policies for proactively managing the challenges presented by…

Gas 2025
Analysis and forecasts to 2030 Global gas markets are set to undergo major changes by the end of the decade, with the coming wave of liquefied natural gas (LNG) production capacity set to profoundly transform market dynamics. The unprecedented scaling up of LNG supply is expected to improve gas supply security and make natural gas more affordable – including in emerging, price-sensitive import markets. However, to account for these shifts, LNG producers and suppliers may need to adapt their medium-term strategies.The Gas 2025 medium-term report from the International Energy Agency (IEA) examines this coming transformation and its…
