Ultra-fast charging batteries
…reduces them by 75%.An electric vehicle battery pack is composed of hundreds or thousands of battery cells, each typically operating at a voltage of around 3-4 volts (V). These cells can be connected in series or in parallel, with series configurations increasing the overall pack voltage to the required level. Most battery electric cars on the market today operate with battery systems of around 400 V, which has long been considered a suitable compromise between charging performance and battery pack complexity, cost and reliability. However, the increasing availability of ultra‑fast charging infrastructure, alongside improvements in battery and vehicle technologies…

Vehicle-to-grid technology
…charging, EV owners can reduce charging costs and, in some cases, generate revenue by participating in grid services, such as frequency regulation. Load shifting and vehicle‑to‑grid (V2G) capabilities provide substantial electricity system benefits, helping reduce peak demand and potentially limiting the need for future grid investment – benefits for which EV owners can be compensated. Vehicle-to-grid charging holds the promise of alleviating grid constraints but barriers remain The rollout of EVs is a major driver of global electricity demand growth. Residential EV charging can draw more power than any other single household load, including heating, cooling, lighting and appliances…

Integrating Distributed Energy Resources in China
Lessons from international experience Like no other country in the world, the People’s Republic of China (hereafter, “China”) is witnessing rapid growth in distributed energy resources (DERs), including rooftop solar photovoltaics, battery storage and electric vehicle (EV) chargers. As China advances towards its carbon peaking and neutrality goals, these resources offer a unique opportunity to support a more flexible, efficient and resilient power system, provided their integration is well-managed.This report analyses recent trends in DER deployment across China and highlights the emerging challenges their growth poses for power system planning and operation, calling for renewed attention to…

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…

Electricity 2026
Global power demand growth continues to rise rapidly as the Age of Electricity gathers pace, supported by the increasing electrification of industry, transportation, and the buildings sectors. Growing consumption is also coming from some of the most dynamic segments of global economies, such as artificial intelligence (AI), data centres, and evolving technological innovations.Against this backdrop, Electricity 2026 – the IEA’s annual report on global electricity systems and markets – provides in-depth analysis of the recent trends and policy developments underpinning this new era. It includes forecasts for electricity demand, supply and carbon dioxide (CO2) emissions for select countries, by…

Manufacturing and Trade Model
The IEA’s Manufacturing and Trade (MaT) Model was first developed for the 2024 edition of Energy Technology Perspectives (ETP) to produce scenario projections of manufacturing and trade across six key energy technology supply chains. These cover solar photovoltaics (PV), wind turbines, electric cars, batteries, electrolysers and heat pumps. This model is now used to generate detailed sector-by-sector and region-by-region long-term scenarios in IEA publications such as the World Energy Outlook and Global EV Outlook.The MaT model is part of the IEA’s broader modelling framework and is closely linked to the Global Energy…

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…

Renewables for Industry
…beverages, textiles, chemicals, paper, and other manufacturing activities. These sectors offer some of the most immediate and cost-effective opportunities for industrial decarbonisation and diversification of energy sources. Commercially available electric technologies – including heat pumps, electric boilers and resistance heaters – can meet most heat demand in these subsectors.Widespread electrification of low-temperature heat and steam in industry, coupled with increasing deployment of renewable electricity supply, can deliver multiple benefits. In addition to reducing fossil fuel use and associated emissions, it can improve energy security by lowering exposure to volatile gas and oil prices and, when integrated with thermal storage…

Emission reductions
…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?
