Global investment in renewables hit $1.8 trillion in 2023 while overall energy investment slipped to $2.5 trillion, a gap that raises an important question about where capital is actually concentrating. At the same time, private funding is taking a larger share of clean energy deployment, including 14.8% of global green energy investment in 2023. From grids and efficiency to venture deals and ESG-linked returns, these statistics trace how money is moving and what that shift could mean next.
Key Takeaways
- 14.8% of global investment in green energy in 2023 came from the private sector (as reported by the IEA), indicating private capital’s growing role in clean energy deployment

- US REITs returned 8.3% in 2023 (FTSE Nareit All Equity REITs total return index), reflecting real estate investment performance
