Admittedly, a hybrid vehicle does emit some carbon dioxide and other greenhouse gases, but only from the gasoline-driven engine. If your vehicle is powered by electricity 50% of the time, it will reduce harmful exhaust emissions by 50%.
Hybrid vehicles are quieter, and cause less noise pollutionan important consideration in urban areas. The engine only runs when the vehicle is being actively propelled forward. Over time, this trait also cuts down on overall energy consumption.
Another obvious benefit is that HEVs run on a fuel source that is already readily available, and that...
