Stronger efficiency is the first and best policy to bring down energy bills
Variations in energy efficiency exist both within and among countries. For example, in some European countries with similar climates it can take twice as much energy to heat the same floor area or within one country the energy consumed between the most efficient and least efficient homes for a given size can vary by a factor of up to three.

World Energy Investment 2025 Japan and Korea
…have made significant investment in clean energy, with 92% of total energy investment going to clean energy compared to a global average of 66%. Investment in low-emissions electricity has grown in the last ten years by around 10% from USD 38 billion to USD 42 billion. 2025 is a critical year for energy policy, with the release of new plans to achieve the twin goals of securing stable energy supplies and accelerating the energy transition. Japan’s Seventh Strategic Energy Plan emphasised the expectation of increased electricity demand and the importance of maintaining energy security. Korea’s 11th Basic Plan for Electricity…

Mali
…its mini-grids by adding PV capacity to diesel power plants. In 2019, Mali’s energy mix was dominated by biofuels and wastes (65%) and oil products (32%), with coal and hydro accounting for the rest. In 2020, less than 5% of the population had access to clean cooking and 52% had access to electricity. For electricity access, the country targets 70% access by 2025, 80% by 2030 and 90% by 2036, with 100% urban access by 2025, and 31% rural access by 2025, 50% by 2030 and 55% by 2036. For clean cooking, Mali targets universal access by 2030.

Global EV Outlook 2025 Outlook for energy demand
Electricity demand Electric vehicles could account for more than 4% of European electricity demand by 2030 In 2024, the global fleet of EVs consumed around 180 TWh of electricity, almost 60% more than the previous year. To put this in perspective, 180 TWh is more than the annual electricity consumption of Argentina. At the global level, EVs represented about 0.7% of final electricity consumption in 2024.The stock of EVs is set to more than triple to 2030, but electricity demand could increase more than fourfold, reaching 780 TWh in the STEPS. This is driven by increasing consumption from electric trucks, as…

Electricity Mid-Year Update 2025 Supply: Renewables grow the most, followed by gas and nuclear
…are key drivers of this trend, with their combined share in global electricity generation expected to rise from 15% in 2024 to 17% in 2025 and to above 19% in 2026 – up from 4% a decade earlier. Wind and solar PV generation together are projected to provide almost an additional 1 000 TWh in 2026, roughly equivalent to the annual electricity consumption of Japan.Global hydropower generation, the largest source of renewable electricity supply globally with a 14% share, is forecast to remain relatively flat in 2025 amid droughts in the first half in various regions, after a significant recovery in 2024…

Switzerland
Switzerland has notably decoupled economic growth from energy use despite strong population growth. This trend should continue, and the energy efficiency first principle should be reflected in all climate and energy legislation. Reaching the 2050 net zero emissions target and addressing the growing winter electricity gap between demand and production requires an unprecedented volume of additional renewable generation capacity, especially wind and hydro. For this, the country needs to shorten the complex and extended administrative and legal permitting process. This will also help advancing investments in grid infrastructure to prepare for more decentralised and variable generation. Switzerland should also align…

Oil Market Report - December 2025
…countries. Highlights Global oil demand is set to rise by 830 kb/d in 2025 amid an improving macroeconomic and trade outlook. These brighter prospects extend to our 2026 forecast, which we have upgraded by 90 kb/d, to 860 kb/d y-o-y. Gasoil and jet/kerosene account for half of this year’s gains, with fuel oil losing ground to natural gas and solar in power generation. In 2026 petrochemical feedstocks will dominate growth, with their share rising to more than 60% from 40% in 2025.Global oil supply fell by 610 kb/d in November, extending…

World Energy Outlook 2022 Outlook for energy demand
The current energy crisis is reshaping previously well-established demand trends. Industries exposed to global prices are facing real threats of rationing and are curbing their production. Consumers are adjusting their patterns of energy use in response to high prices and, in some cases, emergency demand reduction campaigns. Policy responses vary, but in many instances they include determined efforts to accelerate clean energy investment. This means an even stronger push for renewables in the power sector and faster electrification of industrial processes, vehicles and heating. As many of the solutions to the current crisis coincide with those needed to meet…

Hydroelectricity
…In 2024, it generated around 4 500 terawatt-hours of electricity, or 14% of the global total.
More than 150 gigawatts (GW) of new hydro capacity is set to come online by the end of the decade, mostly in emerging and developing economies. As a result, electricity generation from hydropower is expected to increase by 7% between 2025 and 2030. However, its share in global electricity generation is poised to decrease slightly by 2030 as other energy sources, including solar PV and wind, see faster growth.
Annual capacity additions of pumped-storage hydropower are forecast to double by 2030. Pumped…

The State of Energy Innovation 2026 Executive summary
…is innovation-intensive: one in ten patents is related to energy – more than for chemicals, pharmaceuticals or transport.Today, the context for energy innovation tilts towards competitiveness and security. In our survey of experts and practitioners, 80% of respondents placed energy security among the top three drivers of energy innovation in 2025, ahead of affordability, GHG emissions and national economic performance. Many of the innovation-relevant policies announced in 2025, including the US Genesis Mission and the proposed EU Competitiveness Fund, promote technological strength for economic competitiveness and energy security. This may boost technologies that support critical minerals supplies, nuclear…
