Global clean energy market growth forecasts

In August 2026 two separate market outlooks highlighted rapid expansion in clean‑energy technologies. A report on microgrids projected the sector to more than double from about $43.5 billion in 2025 to $95.2 billion by 2030, driven by demand for resilient, uninterrupted power, greater renewable integration, and advances in AI‑enabled software, IoT and digital‑twin platforms. Government policies, regulatory incentives and decarbonisation targets were cited as further catalysts, especially for remote and off‑grid installations.

A parallel forecast for nuclear power focused on small modular reactors (SMRs) and thorium reactors, estimating growth from $63.8 billion in 2025 to $158.7 billion by 2035 (CAGR ≈ 10.7%). The expansion is linked to decarbonisation goals, rising electricity demand from AI data centres, electric vehicles and industrial electrification, and the appeal of modular, low‑carbon baseload power for grid‑constrained regions. The report noted active participation by firms such as NuScale Power, GE Vernova, Rolls‑Royce, Mitsubishi Heavy Industries and Westinghouse, and highlighted collaborative agreements in Japan, the United Kingdom and India to advance high‑temperature gas reactors and thorium fuel cycles.

Together, the forecasts underscore a broader trend of accelerating investment and policy support for diverse clean‑energy solutions worldwide.
