        Nuclear Power

        A new era for nuclear energy beckons as projects, policies and investments increase
        As the world’s second-largest source of low-emissions electricity after hydropower, nuclear power today produces just under 10% of global electricity supply. Now, fresh momentum around the world has the potential to open a new era for nuclear energy.
        Power generation from the global fleet of nearly 420 active nuclear reactors is set to reach a record high in 2025 as Japan restarts production, maintenance works are completed in France, and new reactors begin commercial operations in various markets, including China, Europe, India and Korea…

        …and risk-sharing instruments are essential to scaling up hydrogen projects, particularly for first-of-a-kind deployments and emerging technologies. Collaboration among original equipment manufacturers (OEMs), project developers, public funders and insurers may help reduce perceived risk and strengthen investor confidence.Hydrogen venture capital (VC) fundraising fell by one-third in 2024, outpacing declines in broader energy VC. Publicly traded hydrogen companies have also continued to see lower investor returns and revenues over the past year.Development finance institutions are increasingly backing blended finance structures, with recent disbursements focused on early-stage costs, including projects in Brazil, Egypt, Morocco…

        Gas Flaring

        CO2 emissions
        The volumes of natural gas flared in 2022 were around the same level as in 2010
        Technology deployment
        Oil producers have a range of readily available options to reduce and avoid flaring, with a number of new technologies also under development
        Policy
        A number of countries have introduced policies to reduce flaring
        Investment
        Operators that sell high-flaring assets are often passing on a problem to other operators that may be less willing, or less able, to cut down on flaring

        New Zealand

        New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

        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.

        Global Energy Review 2025 Electricity

        Electricity demand growth surged in 2024 Global electricity demand increased by 4.3% in 2024, a step change from the 2.5% growth seen in 2023. The average pace of electricity demand growth from 2010 to 2023 was 2.7%, double the rate of total energy demand growth over the same period. Electrification picked up across sectors, raising electricity demand in most major economies in 2024. China accounted for the largest share of electricity consumption growth, but increases were seen globallyAlmost all regions saw an acceleration in the rate of electricity consumption growth in 2024 compared with the annual average…

        Tajikistan

        Hydropower is the main source of energy in Tajikistan, followed by imported oil, gas and coal. However, Tajikistan's energy sector is prone to supply shocks, due to seasonal shortages. Energy policy focuses on providing uninterrupted energy access to all users while improving regional co‑operation and energy sector efficiency, but significant domestic and foreign investment will be necessary for continued energy sector development. Tajikistan is part of the EU4Energy Programme, an initiative focused on evidence-based policymaking for the energy sector.
