This document summarizes renewable energy projects supported by UNDP in Europe and Central Asia. It discusses two strategies: supporting market transformation through policies to promote commercial renewable investments, and providing access to affordable energy through small-scale demonstration projects. Key lessons are that supportive policies are critical to promote renewable technologies, which are often available domestically. While financing is important, policies and investment climate are more so. Access to reliable energy is an emerging development issue, and demonstration projects show the potential for scaling up through dedicated policies, financing, and capacity building.
