This document discusses several case studies of market transformation projects related to energy efficiency and renewable energy. It describes projects in China, India, and other countries that aimed to transition markets toward more sustainable technologies. The China case involved establishing minimum energy performance standards for refrigerators which led manufacturers to improve efficiency and consumers to purchase more efficient models. India's renewable energy program provided support to entrepreneurs and helped develop the market for technologies like wind, biogas, and solar water heaters. Other cases discuss energy efficiency standards, labeling programs, and promoting renewable energy adoption in various national contexts. Overall the cases illustrate how market interventions can help mainstream energy efficient and renewable energy options.
