The Hidden Structure of Energy Efficiency Finance

The broader financial system plays a key role in channeling capitals towards energy efficiency technologies to meet the climate goals. In this study, we analyse the market for energy efficiency finance as a complex system, where interactions of heterogeneous investors give rise to large scale investment trends. By analysing the investment system as an evolving network of inter-linked investors, this study identifies the key actors that have directed investment flows in energy efficiency technologies, patterns of investors’ interactions in terms of co-investments and the evolution of the investment landscape. These elements are critical to deploy instruments of public finance and policy effectively to accelerate the energy efficiency technologies deployment.
