- Global energy investment is projected to hit about US$3.3T in 2025, with roughly US$2.2T flowing to clean technologies—more than double fossil fuels.
- Clean-transition investment reached about US$2.1T in 2024, concentrated in EVs, renewables, and grids while hydrogen and carbon capture funding fell.
- Energy and materials M&A is cautious with fewer but larger deals, clustering around renewables, storage, and power infrastructure.
- Meeting net-zero pathways requires scaling clean investment to roughly US$4–5T a year, de-risking hard-to-abate sectors, easing permitting, and attracting more capital to emerging markets.

The latest authoritative sources, including BloombergNEF, the IEA, the World Economic Forum, and the OECD, paint a clear picture of escalating capital flows into the energy transition, but with serious gaps in technology, geography, and pace. These latter-day reports reinforce and expand upon recent insights about how ESG-driven finance and energy policy are shaping the global energy landscape.
Investment Trends & Technology Skew
Globally, clean energy investment topped US$2 trillion in 2024 (US$2.1 trillion per BloombergNEF), and 2025 is expected to push global energy sector investment to about US$3.3 trillion. Of that, clean energy technologies (including renewables, nuclear, grids, low-emissions fuels, electrification, efficiency, and storage) will receive around US$2.2 trillion. In contrast, investment in traditional fossil fuel technologies will lag at about US$1.1 trillion. Key mature technologies—solar PV, grid infrastructure, EVs and storage—are taking most of the money. Emerging technologies like hydrogen, industrial decarbonization, and carbon capture are growing more slowly or seeing year-on-year declines.
M&A and Capital Market Behavior
While cumulative investment is rising, deal activity reveals caution. The Global Energy & Materials sector saw deal count rise modestly in 2024, but total deal value remains below 2021 levels. In power sector M&A by year end 2025, North America leads with roughly US$780 bn in deal value—suggesting fewer deals but much larger size per transaction. Upstream oil & gas transactions are uneven; early 2025 upstream M&A was US$17 b in value, heavily skewed toward a few large players. Loud signals are seen in renewables companies that bundle EV charging, storage, and power assets to attract private equity (e.g., Eni/Plenitude deal).
Strategic Implications & Gaps
A notable shortfall exists vis-à-vis what’s required to stay on course for climate goals. The OECD estimates clean energy investment needs to reach US$4.1 trillion annually during 2026-30 to align with net-zero trajectories, more than double current flows in many regions. There’s also a mismatch: emerging economies are seeing much of energy demand growth, yet most clean capital concentrates in the US, EU, and China. Grid investment is underperforming generation spending, hindering delivery of surplus renewable power. Geopolitical and economic uncertainty has retarded approvals and permitting—particularly for nascent, high-risk sectors.
Open Questions
- Can financing be scaled for emerging technologies (CCUS, electrolytic hydrogen, industrial decarbonization) enough to drive material emissions reductions before 2030?
- How will policy and regulatory frameworks evolve to clear permitting, enable infrastructure build-out, and channel capital into underinvested regions?
- What financial instruments, risk mitigation tools, and partnerships can close the gap between current investment (≈37-50% of need) and what’s needed for net zero pathways?
- How will energy security concerns, rising interest rates, supply chain constraints, and trade tensions reshape the allocation between clean vs fossil fuel investment going forward?
Supporting Notes
- BNEF reports that global investment in the low-carbon energy transition rose 11% in 2024 to US$2.1 trillion, with record levels in electrified transport, renewables, and grid spending.
- IEA projects total energy investment to reach US$3.3 trillion in 2025, with clean energy technologies expected to receive approximately US$2.2 trillion, over twice that of fossil fuels.
- M&A deal value in the Global Energy & Materials sector rose to US$808 billion in 2024 from around US$722 billion in 2022, but number of deals remains modest; deal sizes are increasing, especially in power, renewables, storage.
- In Spain alone, first half of 2025 saw 43 renewables-sector transactions worth ~€6.25 billion, even as deal volume fell about 20% compared to 2024, indicating focus shifting towards higher-value, strategic assets.
- Emerging sectors like hydrogen, CCUS, clean shipping saw investment fall 23% YoY in 2024 per BNEF, lags in maturity, capital costs, and policy certainty cited as causes.
- OECD and IEA data show that to meet Paris-aligned net-zero by 2050, clean energy investment must average ~US$4-5 trillion annually in coming years, meaning current investment is only ~40-50% of required levels globally, particularly in EMDEs outside China.
