Clean power became the top source of new energy worldwide in 2025, signalling a major shift in global investment and policy priorities
Executive summary: In 2025, clean power additions (solar, wind, hydro, nuclear) supplied more new energy than any other source, according to a first reported. The shift underscores a transition away from fossil fuels, affecting investment flows, energy prices, and emissions trajectories.
Who is involved: Carbon Brief analysts, renewable energy developers, utilities, policymakers, and international energy agencies.
Likely next: Further renewable build‑out, potential expansion of subsidies or tax credits, grid upgrades to handle variable output, and ongoing reallocation of capital from fossil‑fuel projects to clean power.
According to Carbon Brief's analysis, renewable additions — including solar, wind, hydro and nuclear — outpaced all other energy sources in 2025, measured by the amount of new capacity added to the global energy supply. This milestone reflects continued cost declines for renewables, strong policy support in many regions, and growing corporate demand for clean electricity. The trend suggests that fossil‑fuel‑based capacity additions will likely keep shrinking unless countered by major policy reversals.
