Clean energy investment hits $2.155 trillion as oil spending heads for third straight decline

Clean energy investment hits $2.155 trillion as oil spending heads for third straight decline IEA data shows clean energy investment more than doubling fossil fuels, but Southeast Asia's fuel crisis exposes a deep dependence on imports. JKM Asian LNG held at $21.19/MMBtu on August 13, keeping gas expensive enough that coal remains the default fuel across much of Southeast Asia — a price signal that sits awkwardly against the largest clean energy investment wave the IEA has ever recorded. [LIVE PRICES]³ Global investment in clean energy reached $2.155 trillion in 2025, more than double the $1.008 trillion flowing into fossil fuels, according to the IEA's World Energy Investment 2026 report.³ The agency projects oil investment will fall below $500 billion in 2026, marking a third consecutive year of decline.³ The direction of capital has been clear for some time. Solar alone is expected to attract roughly $365 billion in investment next year, while grid spending is growing by nearly 20% annually.³ More than 70% of all global power-sector investment now flows into low-emission technologies.³ The investment shift is showing up in generation data. Globally, renewables increased from 32.2 exajoules to 35.4 exajoules in 2025, the fastest-growing major energy category tracked.⁵ In the United States, solar grew more than 28% last year. Solar is no longer a niche contributor; in many regions it is now one of the cheapest sources of new electricity.⁵ Yet the physical fuel system hasn't caught up. A surge in global fuel prices following disruptions around the Strait of Hormuz exposed how deeply Southeast Asia still depends on imported fossil fuels. Governments across the region scrambled to stabilize supply, with coal plants running at higher rates to compensate.¹ The gap between investment flows and physical demand sits in plain sight. Electricity could rise from about 23% to over 50% of global energy use by 2050.² But that forecast assumes grids can absorb the buildout, and fossil fuels remain the balancing mechanism when renewables fall short.² Analysts at Ember are skeptical that recent Southeast Asian fuel buying signals anything structural. "We see this shift as largely a short-term response rather than a long-term direction," said Alnie Demoral, Southeast Asia analyst at Ember. "These measures address immediate supply gaps but don't change the underlying economics pushing utilities toward renewables."¹ The economic and security arguments for renewables have converged. Domestically generated electricity is insulated from conflicts that can disrupt global oil and gas supplies, a point that gained force when Hormuz disruptions pushed fuel prices across Asia.⁴ ICE Brent crude front-month traded at $86.89/bbl on August 13, with the OPEC basket at $85.99/bbl. [LIVE PRICES] For traders, the pattern is familiar. When renewables grow faster than grids can absorb, gas and coal take the swing demand, sustaining fossil fuel price volatility even as investment shifts away from them.³ Dieter Billen of Roland Berger has argued the next phase of Asia's transition will hinge on scalable, commercially viable innovation rather than policy mandates alone.⁶ If Southeast Asian governments treat the Hormuz fuel shock as evidence they need more domestic generation capacity of any kind, the investment mix could shift. If they treat it as a temporary event, the clean energy trend continues largely undisturbed. The commercial viability question Billen identifies — not which technologies exist, but which ones can be financed and built at scale across markets with rising demand — is increasingly the binding constraint.^1,6
