This is a terminal evaluation of a UNEP GEF project implemented between 2001 and 2008. The immediate impact of the SWERA Project was facilitating investment in large-scale use of solar and wind technologies in developing countries and the potential for longer-term impacts. The evaluation aimed at assessing the magnitude and extent of any project impacts and examining the likelihood of future impacts. The evaluation also assessed project performance and implementation of planned project activities by in-country and technical partners, and also outputs related to such activities.
