India expects to become a major solar energy producer, potentially delivering 100GW of solar power by 2022 . In 2022 , 14GW of solar capacity has been approved by the Indian Government , with 20GW planned through 2016 . The Delhi government would “supply expertise” to any poor country that needed help, promising it would “never charge a single rupee”. According to a Deutsche Bank report, capital costs for energy have dropped 40% in past years and the bank predicts that solar investment could overtake coal by 2020 . This sentiment was mirrored by India 's energy minister, Piyush Goyal , who commented that solar has effectively become cheaper than coal. However, investment and growth of renewable energy is a delicate discussion between the rich and developing countries and Piyush Goyal also said that he expected to gain more support for an Indian -global solar alliance in New York this week during the signing of the Paris Agreement .
