Clean energy investment tops $2 trillion as data centers and security concerns reshape power procurement

Clean energy investment crossed $2 trillion globally in 2024, surpassing fossil fuel investment for the first time, according to BloombergNEF. That figure is now setting the baseline for a structural shift that procurement, operations, and infrastructure leaders across multiple industries need to understand, because the forces driving it are directly reshaping where power comes from, who controls it, and what it costs to secure it.

Four forces, one convergence

Beazley's 2026 energy transformation analysis identifies four concurrent pressures accelerating the transition: decarbonization commitments, energy security priorities, investor appetite for returns, and surging electricity demand from data centers. None of these is new in isolation. Together, their simultaneous pressure is producing a pace of change that is outrunning the risk frameworks many operators built in the last decade.

Energy security has become particularly acute since 2022. According to the World Economic Forum, disruptions to global fuel supply chains have pushed governments to prioritize domestic, resilient generation systems over import-dependent fossil fuel infrastructure. Projects that support national energy independence are increasingly being fast-tracked and backed by public funding, which changes the competitive calculus for private developers and the corporate buyers who source power from them.

Regulatory pressure is reinforcing the economics. In the UK, the Emissions Trading Scheme raises the cost base for high-emission operations, making low-carbon alternatives financially attractive rather than just reputationally desirable. In the EU, the Corporate Sustainability Reporting Directive now requires companies to publish standardized, assured sustainability data, tightening scrutiny on supply chains that include carbon-heavy energy sources.

Data centers are rewriting the demand curve

The IEA's Energy and AI report highlights that hyperscale data center operators are not simply buying renewable energy credits on an annual basis anymore. Leading operators are moving to hourly clean energy matching, which tracks and verifies that renewable consumption aligns with actual production in real time. That granularity creates a fundamentally different demand signal for grid operators and developers.

Because hourly matching exposes the variability gaps in wind and solar, it is accelerating investment in technologies that can provide firm, low-carbon baseload power. The IEA notes that hyperscalers are now directing capital into advanced nuclear, including small modular reactors, and geothermal, precisely because those sources can deliver the consistent output that hourly matching requires. For energy procurement teams at large enterprises, this is not a future-state scenario; it is already shaping what technologies attract financing and what supply is available.

Wind, solar, and the infrastructure layer behind them

Solar and wind are no longer experimental. Ember's Global Electricity Review for 2025 shows both sources continuing to grow their share of global electricity generation at record pace. But their variability is driving demand for a broader infrastructure stack: large-scale battery energy storage systems, long-duration energy storage, grid upgrades, green hydrogen, and EV charging infrastructure. Each of these represents both a procurement consideration and an investment opportunity for operators building or expanding facilities.

Battery energy storage systems in particular are attracting significant new capital, with WTW projecting accelerating BESS investment over the next five years as storage becomes a practical requirement rather than an optional supplement to renewable generation. For operations leaders, the relevant question is not whether to engage with these technologies but which counterparties and contract structures carry manageable risk.

Insurance as a capital prerequisite

One operational detail is getting increased attention from project finance teams. Jason Kaminsky, CEO of kWh Analytics, a Beazley company, has stated directly that renewable energy transition projects are not financeable without insurance. Risk transfer, in his framing, is a critical gatekeeper to capital deployment, and gaps in coverage availability directly slow investment into emerging energy systems.

This matters for any enterprise planning to finance or co-invest in energy infrastructure, whether through a power purchase agreement, a direct equity stake, or an on-site generation project. The availability and structure of insurance coverage is not a back-office consideration; it determines whether a project can close financing at all.

Who is funding the build-out

The investor base has broadened well beyond utilities. Infrastructure funds, pension capital, sovereign wealth funds, and large technology firms are taking direct positions in renewable and low-carbon projects, according to Beazley's analysis. Corporate buyers are also shaping what gets built through long-term power purchase agreements that effectively pre-fund development. Utilities remain important, but they no longer control the pace or direction of capacity addition.

The World Bank has noted that filling the funding gaps left by traditional utilities is now a growth opportunity for agile private capital, which can move faster into new technologies and geographies. For procurement and supply chain leaders, this means the counterparty landscape for energy contracts is expanding, with new entrants offering different risk profiles and contract structures than the incumbents they may be accustomed to evaluating.

What this means for your team

• Review your power purchase agreement pipeline for exposure to technology risk in emerging assets like BESS and advanced nuclear, particularly if projects lack established insurance coverage.
• Assess whether your current renewable energy matching approach (annual versus hourly) aligns with tightening corporate sustainability reporting requirements under frameworks like the EU CSRD.
• Map the new entrants in your energy supply chain, including infrastructure funds and hyperscaler-backed developers, against your existing counterparty risk criteria.
• Confirm that any direct energy infrastructure investments or co-development arrangements include risk transfer structures that satisfy project finance lenders, given that coverage gaps can block capital deployment entirely.
