Alternative Fuel Vehicle (AFV) belongs to a growing category of automobiles that utilize substitutes for traditional gasoline and diesel. This shift includes the use of compressed natural gas (CNG), liquified natural gas (LNG), liquid propane gas (LPG), methanol (M85), ethanol (E85), biodiesel, electricity, hydrogen, and fuels produced from organic materials. Fleet managers are actively integrating AFVs into their fleets, a move that brings advantages to both the general public and fleet operators.
The increasing adoption of AFVs is propelled by the escalation of gasoline prices and mounting environmental concerns related to climate change and pollution. To assess the economic impact, it is essential to compare the prices of gasoline, diesel, natural gas, and electricity. Additionally, the efficiency and practicality of alternative fuel vehicle infrastructure should be taken into consideration.
Why Alternative Fuel Vehicle should be considered?
Take into account the following aspects:
- When compared to conventional petroleum vehicles, most AFVs emit less pollution.
- Tax credits and financial incentives contribute to lower overall AFV costs.
- Alternative fuel costs are more consistent and frequently lower than petroleum-based fuels.
- The use of alternative fuels reduces dependency on imported oil.
- Automobile and engine manufacturers are diversifying their AFV and engine offers while fueling station infrastructure is developing.

What are the Benefits of Alternative Fuel Vehicles?
1. Environmental Benefits:
AFVs enhance air quality by emitting fewer pollutants and hazardous substances compared to traditional gasoline and diesel vehicles. These vehicles inherently produce fewer harmful emissions, including significant reductions in evaporative and starting emissions. This positively impacts air quality, global warming, environmental conditions, and public health, especially considering that the transportation sector is the fastest-growing source of harmful pollutants.
2. Economic Advantages:
The economic benefits of AFVs depend on factors like fleet composition, vehicle type, and site-specific considerations. Despite the initial higher capital cost for purchasing or converting vehicles to alternative fuels, the overall lifetime expenses, including fuel and maintenance, are generally lower than traditional gasoline or diesel vehicles.
3. Independence from Imported Oil:
Utilizing domestically sourced alternative fuels decreases reliance on finite and imported oil supplies. This not only mitigates the effects of price and supply fluctuations but also contributes to domestic economic growth by strengthening local fuel sources and expanding the alternative fuels market.
4. Renewable Energy Source:
Alternative fuels derived from renewable sources enhance energy efficiency and reduce dependence on finite resources. For instance, ethanol is produced through the fermentation of corn or other high-starch cereals, while biodiesel is derived from processing vegetable oils. Additionally, both ethanol and biodiesel can be manufactured from recycled materials, reducing waste and tapping into an almost limitless raw material supply.
5. Regulatory Compliance:
The National Energy Policy Act mandates government fleets and alternative fuel suppliers to incorporate AFVs in new light-duty vehicle acquisitions. While the US Department of Energy doesn’t mandate AFV purchases for local governments and private fleets, it’s exploring options such as crediting alternative fuel consumption against AFV purchases and providing credits for obtaining medium and heavy-duty AFVs.
6. Minimized Spill Hazards:
Alternative fuels offer safety and environmental benefits over traditional gasoline and diesel, reducing spill hazards. Natural gas, being lighter than air, disperses quickly in the rare event of a leak, preventing soil and water contamination. Additionally, natural gas has a lower ignition point than petroleum fuels, reducing the risk of combustion. Biodiesel (B100) exhibits lower spill hazards as it is biodegradable and non-toxic, causing fewer environmental problems in the event of a spill compared to gasoline and diesel fuels.
What are the Limitations of Alternative Fuel Vehicles?
- The lack of refueling alternatives at traditional service stations is a significant disadvantage for automobiles that use alternative fuels.
- Many alternative fuel infrastructures are still in their early stages of development.
- Some vehicles can use either gasoline/diesel or an alternative fuel, providing a temporary solution.
- The feasibility of alternate fuels for a fleet must be considered, even when both AFVs and their fuels are already available.
