Global cleantech market size by country 2030

The global market size for key clean energy technologies could reach more than 600 billion U.S. dollars per year by 2030 if countries fully implement announced energy and climate pledges. China would dominate the market, at some 391 billion U.S. dollars per year. Key clean energy technologies include solar PV systems, batteries, wind systems, heat pumps, electrolysers, and fuel cells. Domestic demand in China, the EU, the U.S., and India would account for roughly three-quarters of the global market.

Supplementary notes

The Announced Pledges Scenario (APS) assumes that governments will meet, in full and on time, all the climate-related commitments they have announced as of late 2022, including longer-term net zero emissions targets and Nationally Determined Contributions (NDCs), as well as commitments in related areas such as energy access. It does so irrespective of whether these commitments are underpinned by specific policies to secure their implementation. Pledges made in international fora and initiatives on the part of businesses and other non-governmental organizations are also taken into account wherever they add to the ambition of governments.

Key technologies include solar PV equipment, batteries, wind systems, heat pumps, electrolysers, and fuel cells. Market size is calculated based on module or unit price, excluding installation and construction costs. All market sizes and revenues are expressed in undiscounted 2021 US dollars.
