Electricity Market Design Executive summary
Electricity systems are changing fast, and market design must evolve with them Electricity systems are undergoing rapid structural change, increasing the need for market frameworks that keep pace with evolving operational and investment requirements and possibilities. Electricity is central to modern economies, and its role is expanding as consumption patterns shift, digitalisation accelerates, energy systems decentralise, and variable resources grow. Across major regions, these trends are increasing the complexity of real-time operations and reshaping investment dynamics. Short-term and seasonal flexibility needs are projected to grow faster than demand over the next decade, while electrification in many sectors is…

Energy Efficiency Policy Toolkit Financing Energy Efficiency
Global energy investment continues to grow despite a challenging geopolitical environment. According to the IEA’s World Energy Investment 2026 report, total spending is expected to reach USD 3.4 trillion in 2026, a 5% increase from 2025. Clean energy investment is projected to remain around USD 2.2 trillion, representing nearly two‑thirds of total energy spending and continuing to outpace fossil fuels. Investment in electricity systems such as grids, storage, and electrification, is increasingly driven by energy security concerns and rising electricity demand. Energy efficiency also remains essential to strengthening system resilience, reducing costs for consumers and businesses, and lowering greenhouse gas emissions…

Energy Efficiency Policy Toolkit Transport
Introduction Private cars and vans were responsible for more than 25% of global oil use and around 10% of energy-related CO2-emissions in 2023. Doubling global annual energy intensity improvement by 2030 would require the efficiency of cars to improve by 5% each year. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal.Regulations such as fuel economy standards and heavy-duty vehicle standards encourage manufacturers to introduce more efficient vehicles, thereby significantly reducing greenhouse gas emissions. Countries with regulations and/or efficiency-based purchase incentives in place improve efficiency…

Electricity 2026 Reliability
Largescale outages amid system instability, equipment failures and weather impacts As the Age of Electricity evolves, with steadily rising electrification rates and electricity demand, blackouts can impact a vast part of economies and social life. Outages induced by operational failures, technical error, or climate-driven events illustrate the importance of redundancy, resilience, and thorough oversight. The following list of outage incidents in 2025 underscores how ensuring the security, reliability and resilience of power systems is evolving from a technical challenge to a strategic necessity that requires unwavering attention from system operators, regulators, and policy leaders. Voltage management increasingly important for…

Global Hydrogen Review 2026 Cost acceptability
Analysis of the costs of hydrogen in different end-uses enables identification of the maximum acceptable costs for hydrogen users, i.e. the maximum amount that can be spent on the hydrogen feedstock within a low-emissions pathway while maintaining the same total levelised cost of production as the incumbent pathway to produce the same commodity.This can enable policy makers and investors to identify sectors with both high maximum acceptable hydrogen costs and high potential volumes that can serve as lead markets for low-emissions hydrogen. Cost acceptability can be influenced by policies and depends on technologies, fuels and…

Overview graphic: key technology trends for EVs
GEVO 2026 - Chapter 8 Electric vehicles (EVs) are increasingly at the centre of innovation in the automotive sector, bringing advances that extend far beyond developments in batteries and power electronics, thanks to several mutually reinforcing factors. Key technology trends are aligning in favour of EVs Battery electric vehicles (BEVs) are mechanically simpler than internal combustion engine vehicles (ICEVs) or hybrids, making them more compatible with digitalisation and automation. The relative simplicity of electric drivetrains enables shorter development cycles for new vehicles, allowing emerging technologies to reach BEVs sooner than vehicles with other powertrains.While the transition from mechanical to software…

Electricity Mid-Year Update 2025 Emissions: Power generation CO2 emissions are plateauing
Global emissions from electricity generation rose by 1.2% in 2024, following an increase of 1.6% in 2023. Last year was even hotter than in 2023 – making it the warmest year on record – with the heat waves boosting electricity demand for cooling. Nonetheless, growth in power sector emissions showed signs of slowing down as rapid deployment of renewables constrained increases in fossil-fired generation. As this trend continues, we expect 2025 emissions to plateau and remain relatively unchanged. In 2026, we forecast a slight decline of less than 1%, as the increase in low-emissions generation depresses fossil-fired…

Energy Efficiency Policy Toolkit Buildings
Introduction Buildings account for about 30% of final energy consumption globally and more than half of electricity consumption. Doubling the global annual energy intensity improvement by 2030 would require buildings to become more efficient rapidly. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal. Regulatory standards such as building energy codes are among the most effective policies to not only boost energy performance and reduce emissions, but also to improve occupants' health, comfort and productivity – while enhancing climate resilience and mitigating energy price fluctuations. Buildings built after a code is introduced can…
