Fuel-inefficient

Describing a vehicle, appliance, or system that consumes a relatively large amount of fuel (gasoline, diesel, electricity, etc.) to perform its intended function compared to more modern or optimized alternatives. This often results in higher operating costs due to increased fuel consumption, as well as a larger environmental impact due to greater greenhouse gas emissions. The degree of fuel inefficiency can be quantified through metrics like miles per gallon (MPG) or kilowatt-hours per mile (kWh/mi). The term emphasizes the wastage of fuel and the associated economic and environmental drawbacks.

Fuel-inefficient meaning with examples

• The older model SUV, known for its powerful engine, was notoriously fuel-inefficient. Its low MPG meant frequent trips to the gas station and significantly higher monthly fuel expenses. Environmental groups often criticized it for its substantial contribution to air pollution, highlighting the need for more sustainable transportation choices. Its hefty fuel consumption contrasted sharply with more eco-friendly options emerging in the market.
• Despite its size and storage capacity, the delivery van proved fuel-inefficient, especially during urban routes with frequent stops and starts. Fleet managers were actively seeking replacements that would improve fuel economy to reduce operational costs and comply with increasingly stringent emissions regulations. They began investing in more modern vehicle types to better manage transportation costs.
• My neighbor's vintage car, though beautiful, is incredibly fuel-inefficient. He laments the high cost of keeping it on the road, struggling to balance his passion for classic cars with his environmental concerns and budget restrictions. The car's antiquated technology made it difficult to find any cost effective alternative, making its fuel consumption even more noticeable.
• During the energy crisis, even appliances, such as old refrigerators, were deemed fuel-inefficient. Upgrading to a newer model dramatically reduced electricity bills. Consumers learned the value of energy efficiency standards. The old devices also contributed significantly to the overall carbon footprint of their households, making these replacements even more attractive.
• The company's older manufacturing plant, burdened with aging machinery and processes, was markedly fuel-inefficient, consuming excessive amounts of energy for production. This pushed them to invest in new and improved technologies. This resulted in improved energy efficiency, reduced operational expenses, and decreased emissions. These changes also brought increased profitability to the company.
