The global market value of key energy technologies, including solar, wind, batteries, electric vehicles, heat pumps, and electrolyzers, is projected to reach $1.9 trillion by 2035, International Energy Agency strategists said in a Monday report.
This market value is almost at par with the 2025 value of the crude oil market, IEA said.
Stronger policy support could further raise the market value to $2.6 trillion, with electric vehicles leading the growth, according to the report.
In 2025, the market for key energy technologies exceeded $1.1 trillion following a 20% average annual growth over the past decade. Industries expanded despite declining prices, particularly for solar photovoltaic modules, IEA noted.
"Cross-border trade has supported the rapid scaling of these energy technologies, even as trade policies affecting them have become more restrictive," the agency said, citing tariffs, duties, and local-content provisions as examples.
In terms of demand, IEA highlighted that cost-competitiveness and fossil fuel security concerns have largely driven growth for these technologies.
In the EU, fossil fuel imports as a share of total energy consumption are expected to fall to 40% in 2035 from 55% in 2024, while energy technology imports are projected to rise to $165 billion from $65 billion.
At the same time, IEA noted that exports from China, a major technology manufacturer, could more than double to $735 billion by 2035.
The agency also said that "manufacturing investment is cooling as capacity remains comfortably above today's demand levels," although "growth is taking place in several regions," such as the EU, Korea, and India.
Going forward, IEA sees that increased domestic manufacturing will strengthen the supply chain, while international trade will be key to meeting demand as technology deployment surges.
