He claimed India would not become a developed nation unless the per capita electricity consumption increased by six to eight times from the present level. "So, all the energy options are necessary and important."
In the next 20 years, he said growth will come on account of substantial reduction in coal consumption by thermal power plants with development of new technologies.
