New Delhi, Feb 14: A new research by US-based Institute for Energy Economics and Fincial Alysis (IEEFA) on Wednesday showed how nine major global power markets, including India’s Tamil du, have achieved an outsize share of wind and solar generation while assuring the security of supply. They are providing compelling examples of the fast-moving evolution of electricity generation. The report, ‘Power-Industry Transition, Here and Now’, includes case studies of markets — ranked by relative share of reliance on variable renewables — that include Denmark, South Australia, Uruguay, Germany, Ireland, Spain, Texas, California and the Indian state of Tamil du.
