Zero Emission Vehicles (ZEVs) encompass vehicles that operate without emitting carbon emissions. While ZEVs can include mechanically-propelled and wind-propelled vehicles, their primary focus is on replacing traditional gasoline, diesel, jet fuel, or petroleum-based propellant-powered vehicles. Most ZEVs employ an efficient electric drive system, high voltage storage batteries, rapid charging, and onboard electric power generation methods like brake regeneration and solar panels.
Who are the Primary Adopters of Zero Emissions Vehicles (ZEVs)?
Municipalities, particularly major cities, have been leading adopters of Zero Emission Vehicles (ZEVs). They have addressed issues of air, water, and noise pollution that affect the health and quality of life of residents and visitors. By replacing old, polluting diesel and gasoline-powered city buses, work trucks, and other vehicles with clean and quiet ZEVs, cities have significantly reduced exhaust and noise pollution. This success has also driven the adoption of ZEVs in various transportation sectors, including tour boats, school buses, commuter rail locomotives, and taxi fleets.

What are Common Types of ZEVs Recognized by Regulations?
Common configurations of Zero Emission Vehicles (ZEVs) that comply with state and federal regulations include:
1. Full battery electric vehicles, rely solely on batteries and produce zero emissions by using electricity to propel the vehicle. These BEVs may utilize regenerative braking and solar panels for additional electricity generation.
2. Hydrogen fuel cell electric vehicles (FCEVs), generate electricity by combining hydrogen and oxygen in a clean, noiseless process, producing only heat and water as by-products. FCEVs often incorporate regenerative braking and solar panels.
3. Plug-in electric hybrid vehicles, which can be charged overnight but also have an internal combustion engine to keep their batteries charged during longer trips. Although they emit some carbon, these hybrids are considerably cleaner, more efficient, and quieter than traditional internal combustion engine vehicles.
