Asset values
…or renters. Increasing the quality of a rented space through energy efficiency can achieve increased thermal, noise and light comfort; improved health, safety and security, and reduced energy bills and operational costs. These benefits can result in improved tenant satisfaction and improved ability to rent the space.Rent increases associated with the retrofit should be in line with energy cost savings to maintain affordability. Policy tools, such as mandatory energy performance ratings, financial incentives and tenant protections, can help ensure that asset value gains benefit both owners and occupants, especially vulnerable groups such as low-income households. Meanwhile, a landlord…

The Value of Demand Flexibility
Benefits beyond balancing This policy brief, developed under the International Energy Agency’s Digital Demand-Driven Electricity Networks (3DEN) Initiative, examines the value of demand flexibility as a core component of modern electricity systems, with a strong emphasis on its role in improving energy efficiency. As electricity demand grows and power systems become more electrified, decentralised and renewable-rich, managing when and how electricity is used is increasingly as important as expanding supply.The brief sets out a clear framework for understanding demand flexibility and highlights its contribution to an efficiency-first approach to power system planning and operation. By…

Health
Multiple benefits of Energy Efficiency 2025 Energy efficiency provides multiple benefits. This page explores health. Why is energy efficiency important for health? Energy efficiency can improve health by creating healthy indoor and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the…

Electricity Market Design
Building on strengths, addressing gaps Electricity markets play a central role in balancing supply and demand, guiding operational decisions and shaping investment outcomes. As systems change with higher shares of variable generation, greater decentralisation and evolving patterns of electricity use, the ability of market designs to deliver secure and affordable electricity has never been more critical. If market arrangements do not keep pace with these developments, the functioning of electricity systems could become more uncertain and more costly.This report provides a cross-regional assessment of how wholesale electricity markets and their complementary policy mechanisms are performing today. We find…

Multiple Benefits of Energy Efficiency
As energy efficiency continues to gain attention as a key resource for economic and social development across all economies, understanding its real value is increasingly important. The multiple benefits approach seeks to expand the perspective of energy efficiency beyond the traditional measure of energy savings by identifying and measuring its impacts in full bloom.

Gaining an Edge
The Role of Energy Efficiency in Enhancing Competitiveness Energy efficiency delivers more than energy savings and emission reductions – it can also improve the competitiveness of countries and firms. From increased profitability to job creation, energy efficiency helps firms compete amid high costs, growing demand, and rising trade pressures. In today’s global context, energy efficiency is not only a matter of energy policy, but also of economic policy.The report analyses historical progress in industrial energy efficiency and its role in enhancing industrial competitiveness. It includes comparisons of firm-level energy efficiency, identifying performance gaps and opportunities for further improvement. Drawing…

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…

China’s Official Energy Finance in Emerging and Developing Economies
Evolving institutions, instruments and implications for clean energy transitions Global energy investment exceeded USD 3.3 trillion in 2025, but capital flows remain uneven. Emerging market and developing economies (EMDE) outside China attracted just 27% of total energy investment and 18% of clean energy spending, despite accounting for nearly two-thirds of the global population and the bulk of future demand. Addressing this imbalance requires mobilising more capital from diverse sources into EMDE energy systems.China continues to play a central role in global energy investment flows because of its large domestic investments and its large external capital spending on energy. Since…

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…

Emission reductions
…lack access to clean cooking, air pollution is linked to around 3.7 million premature deaths a year. Replacing open fires and inefficient stoves with cleaner, more modern stoves and fuels reduces household air pollution and improves efficiency. Indoor air pollution from liquid petroleum gas (LPG) cookstoves is only around 5% of pollution from traditional biomass, while being over three times more efficient. Switching from LPG to electric cooking would further reduce indoor air pollution by 25% and is over 1.5 times more efficient. Need more information?
