In a first of its kind initiative, Prime Minister Narendra Modi on Sunday unveiled a Rs 8,000-crore scheme to provide domestic cooking gas connections to five crore BPL families over the next three years. The scheme is touted to be a gamechanger by many analysts as it could free poor households from the health hazards of inhaling smoke from chulhas fuelled by firewood or dung. “We have shown how the petroleum sector is for the poor,” Modi said at the launch of Pradhan Mantri Ujjwala Yojana here, nearly 400-km from Lucknow.
