Connecting clean energy entrepreneurs to financing

CTI PFAN video icon‌‌Efforts to scale up investment in clean energy technology are often unsuccessful due to the problem of the "missing middle": many clean energy entrepreneurs have good ideas but cannot find financing, while many investors have difficulties identifying and vetting attractive investment opportunities.  The CTI Private Financing Advisory Network (CTI PFAN), seeks to bridge that gap by mentoring emerging clean energy entrepreneurs to build project proposals and present them to a network of investors and financial institutions interested in clean energy markets.  Have a project you want to develop? Watch this short video to learn more about CTI PFAN networks and operations.
