The era of near-zero interest rates is gone, and it has reshaped energy finance. Renewable energy projects are capital intensive—you spend all the money upfront to build the wind farm, then collect pennies for 20 years. High interest rates hurt this model.
In 2026, we are seeing a flight to quality. VCs are no longer funding “moonshot” energy tech. Capital is flowing to Brownfield projects—upgrading existing infrastructure—rather than Greenfield risks.
Furthermore, “Green Bonds” have matured. Lenders are demanding rigorous data. You cannot just claim to be green; you must prove it with real-time data. This has made Energy Accounting—the software that tracks and verifies every electron and carbon atom—one of the fastest-growing software verticals in the world.
