DUE to high fuel pump prices, there has been a surge of interest in petrol-electric hybrid vehicles.
For instance, hybrid car sales all over the world, dominated by the Toyota Prius, saw a marked increase in the last four year despite a declining new passenger car market.
It has been reported that waiting lists to buy the Prius was stretched to as long as six months in the United States, due to limited supply of batteries for the hybrid car.
Presently, it seems that combining electric drive with the internal combustion engine is the best choice for reducing fuel consumption and emissions.
Hybrid vehicle technology is easily available and it does not require too much engineering.
