The Centre on Monday said that public transport may be modernised which is based on biofuels, CNG and electricity as fuel. Union Road Transport Minister Nitin Gadkari said most of the State Road Transport Undertakings (SRTUs) are incurring huge expenditure on conventional fuels which are expensive. The Minister called for moving on to biofuels, Gadkari said also urged the bus operators to consider providing better services like good attendants, provision for entertainment tools like audio music, video films, etc which can fetch better returns. “CNG and Electricity as transportation fuel. It will not only save on fuel bill but also contribute to economy and pollution reduction. At present country is spending huge amounts on import of crude oil/hydrocarbons, which need to be reduced,” Gadkari said addressing a Webinar - 4th UITP India Bus Seminar.
