Powering Ireland’s Energy Future
Approaches for a secure, renewables-led electricity system to 2035 Ireland has emerged as a frontrunner in integrating wind power, which supplied around a third of its electricity in 2024. As this power system transformation continues, electricity is set to be the backbone for achieving Ireland’s climate, energy and socio-economic ambitions, making electricity security critical to realising progress in key areas including housing, digital infrastructure, transport and heat. Going forward, Ireland faces strategic choices on how to align its ambitions while ensuring secure electricity supply to 2035.This report assesses the outlook for Ireland’s energy security to…

China
China’s growing energy needs are increasingly met by renewables, natural gas and electricity. The scale of China’s future electricity demand and the challenge of decarbonising the power supply help explain why global investment in electricity overtook that of oil and gas for the first time in 2016, and why electricity security is moving firmly up the policy agenda. That said, cost reductions for renewables are not sufficient on their own to secure efficient decarbonisation or reliable supply.
Between 2019 and 2024, China will account for 40% of global renewable capacity expansion, driven by improved system integration, lower curtailment…- Overview

Vehicle-to-grid technology
GEVO 2026 - Chapter 8 With the rollout of smart and bidirectional 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…

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…

How accelerating electrification could strengthen energy security in Southeast Asia
Commentary Electrification is key to energy security and sustainability across Southeast Asia Energy demand is rising rapidly in Southeast Asia, driven by economic growth, industrialisation, urbanisation and rising incomes. Since 2015, energy demand has risen by around 40%, while electricity demand has grown even faster – twice as fast as overall energy use. Although renewables have increased significantly over the past decade, fossil fuels have continued to dominate, meeting over 70% of energy demand growth across this period, with oil accounting for nearly half of total energy consumption.Rapid energy demand growth and continued dependence on fossil fuels brings greater exposure…

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…

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…

7 certainties about energy for this age of uncertainty
ED commentary The energy sector, like many others, is contending with a blizzard of uncertainties, complicating the work of policymakers, business leaders and investors.Geopolitical twists and turns are straining long-established relationships and upending deeply held assumptions. The World Uncertainty Index, devised by economists from the IMF and Stanford University, has hit unprecedented levels in recent months.But in this time of flux, there are still some important trends that we can identify with some confidence. Here are seven that can help us keep our bearings: The world has entered the age of electricity Oil and gas will still…

Electricity Mid-Year Update 2025
Despite a slowdown in global economic growth prospects, the world’s electricity consumption increased strongly in the first half of 2025, driven by rising demand from industry, appliances, cooling, data centres and electrification. At the same time, electricity supply from renewables, natural gas and nuclear continues to grow, with all set to reach new milestones.This mid-year update follows the extensive Electricity 2025 report released in February, examining the latest trends and the outlook for the remainder of the year. It includes updated data for 2024 along with new forecasts for 2025 and 2026 covering areas such as global…

Clean Energy Technology Supply Chain Data
Challenges and potential solutions Energy security in the Age of Electricity is inextricably linked to securing the supply chains for clean energy technologies and the equipment and materials used to manufacture them. As countries continue to pursue energy transitions and to direct investments to these technologies, guided by industrial strategies, a detailed understanding of their supply chains has an essential role to play. The availability of good-quality, timely data is crucial to gaining this understanding and to identifying and addressing supply chain vulnerabilities.This report is provided as an input to the discussions taking place as part of the…
