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…

Financing the Modernisation of Power Systems Beyond Coal
…central component of power systems in Southeast Asia, even as governments have committed to reducing coal‑related emissions. Rapid electricity demand growth, alongside coal’s role in system adequacy, reliability and energy security, complicates efforts to accelerate coal transitions. Recent volatility in international gas markets has reinforced the short‑term economic and security value of existing coal assets, adding complexity to national transition strategies. The region’s young coal fleet also implies substantial long‑term emissions if plants continue operating at current utilisation rates.Against this backdrop, new approaches are being explored to support coal transitions while maintaining secure and reliable power systems…

Household Energy Affordability
Energy is one of the top expenses for millions of households, making energy affordability an important policy concern for governments. The impacts of the global energy crisis on consumer prices have been significantly felt in household budgets. Despite coming down from their peak in 2022, prices remain elevated compared to pre-crisis levels and households continue to grapple with higher living costs.This report sets out to identify key trends that are shaping the state of energy affordability around the world today. It explores how system drivers and household energy consumption influence the makeup of energy bills and opens a…

Vehicle-to-grid technology
…networks. As power systems in many regions simultaneously integrate higher shares of 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…
