Global Energy Investment Dramatically Favors Cleantech, but the U.S. is Falling Behind
by Bob Shively, Enerdynamics President and Lead Facilitator
The recent World Energy Investment 2025, released by the International Energy Agency, reveals a dramatic transformation in global energy spending, which is expected to reach an unprecedented $3.3 trillion in 2025. These investment patterns indicate what the future holds.
The Clean Energy Revolution Takes Center Stage
The most striking trend is the clear dominance of clean energy investment, which now captures $2.2 trillion annually, exactly double the $1.1 trillion flowing into oil, natural gas, and coal. This represents a fundamental shift from just a decade ago, when fossil fuel investments significantly outpaced spending on clean energy.
Solar photovoltaic technology leads this transformation, attracting $450 billion in investment and becoming the single largest category in global energy spending. This surge reflects dramatic cost reductions, with the prices of clean energy equipment having fallen by 60% over the past decade. The rapid deployment of electric vehicles, battery storage systems, and renewable power generation demonstrates that clean technologies are no longer experimental—they're becoming the economic backbone of the global energy system.
However, the picture isn't uniformly optimistic. Investment growth is slowing compared to previous years, with clean energy investment increasing by just 6% in 2024 versus the dramatic expansions seen in 2021-2022. Higher interest rates, supply chain constraints, and policy uncertainties are creating headwinds that professionals must consider when developing their investment strategies. Especially significant is the reversal of policy in the United States to no longer support most clean energy technologies.

China Leads, Others Follow
China has emerged as the undisputed leader in global energy investment, accounting for nearly one-third of all clean energy spending worldwide. Chinese companies are not only dominating domestic markets but expanding internationally, with $80 billion announced for overseas electric vehicle and battery manufacturing facilities over the past five years. This aggressive expansion strategy positions China as a potentially dominant player in future global energy supply chains. China is already the world leader in photovoltaic solar, batteries, and electric vehicles.
Europe's Energy Security Drive
Europe's investment story is intimately connected to energy security concerns following Russia's invasion of Ukraine. The region has dramatically accelerated clean energy spending, reaching $390 billion in 2025, making it the third-largest global investor. European investment is characterized by a massive shift away from fossil fuel generation—the ratio of renewable to fossil power investment has jumped from 6:1 in 2015 to 35:1 in 2025. However, Europe faces unique challenges. Grid infrastructure investment, while growing, hasn't kept pace with renewable deployment, creating bottlenecks and price volatility across member states.
The U.S. Risks Falling Behind
The United States presents a more complex picture. While clean energy investment has grown substantially, nearly doubling over the past decade, growth is now plateauing as policy support scales back. American investment patterns are now focused on artificial intelligence-driven data center development, which could require an additional $170 billion to $340 billion in power infrastructure by 2030. Although the US leads in venture capital funding for energy innovation, venture capital has struggled to become a driving force in clean energy technologies that often take longer to develop than software-based solutions. The current U.S. administration favors investment in traditional sources such as oil, natural gas, and existing coal units rather than fostering any clean tech sources other than nuclear energy. This leaves the clean tech industries in China and Europe, which see more significant government support, the opportunity to surpass U.S. companies.
Critical Challenges Ahead
Several global trends are worth observing:
- Upstream oil investment is set to fall for the first time since 2020
- Electrification is shaping investment trends
- Clean power generation remains the preferred destination for new power sector investment, but grids remain a constraining factor with significant upgrades needed to maintain renewable energy growth
- Current growth in nuclear is primarily due to Chinese investment in traditional large-scale reactors although new nuclear technologies may emerge soon
- Expectations of rising demand and security concerns are resulting in ongoing investment in fossil fuel power plants, especially natural gas
- Investment in utility-scale batteries continue to grow as costs decline, and global battery storage investment is approaching the level of gas-fired generation investment
For energy professionals, these trends signal a sector in transition where traditional investment patterns no longer apply. The world is moving to an electric system driven by clean energy, battery storage, electrification, and ongoing investments in grid upgrades. Current federal policy in the U.S. risks ceding leadership in future energy technologies to China and Europe.
