Improve Roadside Air Quality
Pure Electric Vehicles are powered by batteries only and therefore emit zero roadside emissions. Even if taking into account the emission from power generation, carbon emissions from electric vehicles still less than gasoline vehicles. Extensive use of electric vehicles will improve road-side air quality in Hong Kong.
In general, electric vehicles convert more than 80% of their input energy into useable power, compared to conventional gasoline vehicles which have efficiencies as low as 15-20%.
The high energy efficiency of electric vehicle means that it could dramatically reduces fuelling costs. For example, assuming that a private vehicle in Hong Kong runs about 40 to 60km a day, the electricity costs incurred for an electric vehicle is less than $11, which is cheaper by about 80% compared to a conventional vehicle.
Quiet and Smooth
Vibration and noise are drastically reduced with the use of electric vehicle. Since electric motors do not rely on a chemical combustion process, they produce almost no vibration and noise compared to a conventional combustion engine. Electric vehicle gives the driver and passenger a quieter and smoother ride compared with gasoline counterparts.
