"We have 1.5 lakh buses of state road transport corporations. It is our effort to convert 1.5 lakh diesel buses into electric battery-operated buses which will reduce Rs 8 lakh crore bill on import of crude and petroleum and would also help in making India pollution free," the Road Transport and Highways Minister said.
To make India pollution free, the country needs to encourage electric vehicles besides vehicles run on environment-friendly fuel like bio-diesel and ethanol, the minister said while addressing a convention on 'Green Highways.'
"If we want to make the country pollution free then diesel and petrol vehicles should be converted into electric vehicles. Our department has taken a decision that lithium ion battery would be patented and its price will come down to about Rs 6 lakh," he said.
He said at present such batteries are imported at a cost of about Rs 55 lakh but ISRO in collaboration of Highways bodies and ARAI (Automative Research Association of India) was developing indigenous batteries.
