"For promoting renewable energy, what multilateral agencies have to do... Create 10-30 per cent portfolio of total credit exposure which must go to the renewable energy sector. It is easy to find money, but the problem is cost of capital," Tripathy said addressing a session organised by the World Business Council for Sustainable Development (WBCSD).
He further said the main challenge (to meet renewable energy targets) comes from the capital requirement of USD 200 billion in over seven years.
Tripathy also sought support of WBCSD for International Agency for Solar Policy & Application, which brings together "sunshine countries" located between the tropics of Cancer and Capricorn, to take the initiative forward.
On this occasion, WBCSD launched an innovative renewable energy programme in India as part of a series of national dialogues being held across the world in September and October.
