Private markets

raised almost US$230 billion for

energy-transition funds

over the past decade, creating a growing source of financing for

clean energy

and other

renewable projects

, according to BloombergNEF.

Much of that capital remains undeployed. About US$92 billion is still sitting on the sidelines, said Ryan Loughead, a senior associate at BNEF in London. “It’s a pocket of money that’s increasing and it’s not inconsequential,” he said.

and Copenhagen Infrastructure Partners are among the asset managers betting that rising energy demand and the improving economics of renewables will continue to drive investment. The funds are emerging as “a significant source of capital” for the energy transition, BNEF wrote in a report published Thursday.

Even so, the world remains far short of what’s needed to avoid the worst effects of climate change. BNEF estimates annual spending of US$5.2 trillion is required through the end of the decade for the global economy to stay on track for a net zero scenario. Last year, a record US$2.3 trillion was invested in electrified transport, renewable energy, power grids and other green businesses, leaving the world well behind pace.

Based on available data, BNEF estimates that the median internal rate of return for dedicated transition funds ranged from an annualized seven per cent to more than 20 per cent between 2015 and 2022, though the payback period varies significantly.

Private markets — investments in assets not traded on public exchanges — have expanded rapidly. Globally, assets under management in private capital climbed almost 20-fold to about US$22 trillion between 2000 and 2024, according to estimates from McKinsey & Co.

In all, private markets have raised US$2.7 trillion for funds investing in all sorts of energy,

including fossil fuels

, over the past decade, BNEF reported.

Brookfield Asset Management has done a series of big green deals in recent years, including a £1.75 billion (US$2.4 billion) stake purchase in United Kingdom offshore wind farms from Orsted A/S. The asset manager also partnered with Microsoft Corp. in 2024 in what was then the largest announced corporate clean-energy purchase agreement.
