                …The annual offshore wind market expands from 9.2 GW in 2024 to over 37 GW by 2030, with China accounting for almost 50% of this increase. In Europe, the annual market is expected to approach 14.6 GW by 2030. Policy changes in the United States, macroeconomic pressures and supply chain challenges have raised costs and undermined project bankability in several European markets and Japan, resulting in undersubscribed auctions and project cancellations. As a result, we have revised the global offshore wind capacity forecast 27% downwards from last year.Hydropower growth from 2025 to 2030 is expected to be slightly higher than…

                How and where is energy used? Total final consumption in 2024 was over 450 EJ and has grown by around 25 EJ since 2019. Buildings account for around 30% of global energy demand and have contributed around 20% of the growth in total demand since 2019. The residential sector makes up about 70% of total energy demand in buildings, while the remaining 30% is used in commercial and public buildings.In advanced economies, most energy in homes is used for space and water heating, together accounting for about 70%. This is followed by the use of electrical appliances, such as refrigerators, televisions…

                Sheltering From Oil Shocks Introduction and contextIntroduction and context

                The conflict in the Middle East has created the largest supply disruption in the history of the global oil market. The volume of fuel supply offline now is higher than the supply loss during the oil shock of 1973 that led to the IEA’s creation and any disruption since then. Beyond the direct damage to energy infrastructure in the region, the crisis has led to a near halt in tanker movements through the Strait of Hormuz. Crude and oil product flows through the Strait have fallen from around 20 million barrels per day (mb/d) before the conflict to…

                In the past, Southeast Asia’s rapid economic growth was mostly driven by fossil fuels but clean energy now accounts for almost half of energy investment Southeast Asia is a rapidly developing region, with GDP per capita increasing by more than 30% since 2015. During the last ten years, energy demand has increased by over 35%, with electricity demand rising by more than 60%. Driving this is a 12% increase in electricity access rates, growing consumption in industry, urbanisation and rising incomes creating demand for cooling and other appliances. Historically, this rising energy demand has been met by fossil fuels…

                The Value of Demand Flexibility Executive summaryExecutive summary

                With global electricity demand rising and set to add around 1 000 TWh each year until 2035, new ways of managing the balance between supply and demand are needed. Demand flexibility – the ability to adjust the timing or amount of electricity use in response to system needs – is central to help achieve this balance. Advances in digitalisation, including the growing use of AI tools, are further enhancing the ability to deploy flexibility effectively.This policy brief, part of the 3DEN Initiative, presents a concise framework for understanding demand flexibility and its value across the energy system, highlighting that it can:Enhance power…

                Energy Efficiency Policy Toolkit IndustryIndustry

                Introduction Industry accounts for 37% of final energy consumption globally. Doubling global energy intensity improvement by 2030 would require the decoupling of production from energy demand and raising the share of electricity in energy use from 23% in 2022 to 30% in 2030. An integrated policy approach combining regulation, information and incentives is the most effective way to achieve this goal.Regulations such as minimum energy performance standards for motors increase the efficiency of industrial processes by requiring new motors to use less energy per unit of output. This also drives the innovation of more efficient technologies. The alignment of international…
