The International Energy Agency projects renewables will supply nearly 45% of global electricity by 2030, transforming aluminium production regions and highlighting uneven progress amid policy and supply chain challenges.
Renewables are moving from a supporting role to a central one in global power systems, with the International Energy Agency now projecting that they will supply almost 45% of electricity generation by 2030. The agency says renewable generation is set to rise from 9,900TWh in 2024 to 16,200TWh by the end of the decade, overtaking coal by the end of 2025, or by mid-2026 at the latest depending on hydropower conditions. Solar PV is expected to deliver more than half of the increase, while wind will account for about 30%. (iea.org)
For industrial users, that shift matters as much as it does for utilities. Electricity is the main cost driver in aluminium smelting, so the pace and geography of clean power build-out will shape where low-carbon metal can be produced competitively. The strongest growth is still concentrated in China, Europe, the United States and India, which are also among the world’s most important aluminium-producing regions. In the IEA’s latest outlook, China remains responsible for nearly 60% of global renewable capacity growth, while India is on course to become the second-largest growth market and the European Union is seeing stronger solar deployment driven in part by corporate power purchase agreements. (iea.org)
The scale of the expansion is already visible in the numbers. IRENA said renewables accounted for 92.5% of all global power capacity additions in 2024, with 585GW added in a single year and total renewable capacity reaching 4,448GW. The agency described that growth as a record, but said the world still needs much faster annual expansion to stay aligned with the target of tripling renewable capacity by 2030. (irena.org)
Electricity data from the IEA shows the transition is already altering the global mix. Clean energy accounted for more than 80% of the growth in power generation in 2024, while renewables supplied roughly one-third of total electricity worldwide. The agency expects renewables to meet more than 90% of global electricity demand growth between 2025 and 2030, a dynamic that should gradually improve the carbon intensity of grid power in key industrial markets. (iea.org)
Yet the outlook is not without friction. The IEA warns that grid integration, supply chain constraints, financing pressure and policy shifts are all weighing on the pace of deployment. It has also cut its forecast for US renewable growth sharply, citing policy changes including earlier tax credit phase-outs and tighter permitting conditions, while China’s move from fixed tariffs to auctions is affecting project economics. For heavy industry, that means the availability of genuinely low-carbon electricity may improve unevenly, rather than uniformly, across major aluminium hubs. (iea.org)
That unevenness is the key question for aluminium producers. Where clean power can be contracted at scale, smelters will be better placed to cut emissions and shield themselves from fossil-fuel volatility. Where grids remain coal-heavy, the decarbonisation case will depend more on long-term power procurement, transmission upgrades and new capacity additions than on the headline growth rate of renewables alone.

- https://www.iea.org/reports/renewables-2025/executive-summary – The International Energy Agency’s ‘Renewables 2025’ report projects that global renewable power capacity will double by 2030, increasing by 4,600 gigawatts (GW). Solar photovoltaic (PV) is expected to account for almost 80% of this growth, followed by wind, hydropower, bioenergy, and geothermal. The report also highlights that in more than 80% of countries worldwide, renewable power capacity is set to grow faster between 2025 and 2030 than it did over the previous five-year period. However, challenges such as grid integration, supply chain vulnerabilities, and financing are also increasing.
- https://www.iea.org/reports/renewables-2025/renewable-electricity – The IEA’s ‘Renewables 2025’ report indicates that electricity generation from renewables is expected to increase by 60%, from 9,900 terawatt-hours (TWh) in 2024 to 16,200 TWh in 2030. Renewables are projected to surpass coal by the end of 2025 or mid-2026, becoming the largest source of electricity generation globally. Solar PV alone is expected to account for over half of this increase, followed by wind (30%). The share of renewables in global electricity generation is projected to rise from 32% in 2024 to 43% by 2030, while the share of variable renewable energy sources is set to almost double to 27%. Over 2025-2030, renewables are expected to meet over 90% of global electricity demand growth.
- https://www.iea.org/reports/global-energy-review-2025/electricity – The IEA’s ‘Global Energy Review 2025’ highlights that clean energy accounted for over 80% of total growth in electricity generation in 2024. Global electricity generation grew by over 1,200 TWh, with renewables and nuclear power making up over 80% of this growth. In 2024, renewables collectively accounted for one-third of electricity generation, led by hydropower (14%), wind (8%), solar PV (7%), and bioenergy and waste (3%).
- https://www.irena.org/News/pressreleases/2025/Mar/Record-Breaking-Annual-Growth-in-Renewable-Power-Capacity – The International Renewable Energy Agency (IRENA) reported that in 2024, renewables accounted for over 90% of total power expansion globally, with 585 GW of capacity additions. This marks a record rate of annual growth (15.1%). However, progress still falls short of the 11.2 terawatts needed to align with the global goal to triple installed renewable energy capacity by 2030. To reach this goal, renewable capacity must now expand by 16.6% annually until 2030.
- https://www.c2es.org/content/renewable-energy/ – The Center for Climate and Energy Solutions (C2ES) reports that globally, renewables made up 32% of electricity generation in 2024, an increase of 7% from the previous year. Additionally, 741 GW of renewable power capacity was added globally during 2024. In the United States, renewables made up 22.7% of utility-scale electricity generation in 2024, with the bulk coming from hydropower (5.6%), solar (5.1%), and wind power (10.5%).
- https://www.iea.org/news/global-renewable-capacity-is-set-to-grow-strongly-driven-by-solar-pv – The IEA’s news release indicates that global renewable power capacity is expected to more than double by 2030, driven by the rapid rise of solar PV. This expansion is taking place amid challenges such as supply chain strains, grid integration issues, financial pressures, and policy shifts. The report highlights that renewables’ expansion is occurring in a context of these headwinds, emphasizing the need for supportive policies and investments to sustain growth.
