India and the United States have tremendous opportunity for cooperation in the domain of clean technologies to ensure sustainable energy security for both countries. A joint report by the Atlantic Council and CII, suggests that expanding cooperation will be essential to overcoming energy shortages in the coming decades. Numerous opportunities for cooperation are identified in the report; both countries should establish an umbrella Memorandum of Understanding (MoU) that covers all promising clean energy technologies such as clean coal technologies, bio-fuels, hydrogen/fuel cells and renewables. The report also stresses the need for maintaining a favorable investment climate by opening domestic markets to international expertise and capital, removing limitations on foreign investment in new technologies and service companies, strengthening intellectual property protection for Indian and US products and processes, and sharing experiences in developing effective programs and policies.
