The cost of electric and hybrid cars, with the added factor of electricity shortages, make 'green cars' a rare sight on Indian roads. The Prius in India costs $40,000. Only 12,000 battery powered scooters and motorcycles were sold in 2010. With the right economics and convenience the situation could change. About 1 million compressed natural gas vehicles are on Indian roads, according to Asian NGV. This is because CNG vehicles are similiar in price to gasoline vehicles and the switch to CNG is inexpensive for regular vehicles.
