Industry
Hydrogen fuel for fleets, explained
Quick answer: Hydrogen fuel cell trucks are operating in pilots today, mostly in California ports and regional drayage. Pump prices for hydrogen remain high ($9–$18/kg in 2025) and station coverage is limited, so most fleets should plan for hydrogen in specific duty cycles rather than a general replacement.

Industry
EV vs gas: fuel cost per mile, side by side
Quick answer: At typical U.S. residential rates ($0.16/kWh) and a 3.5 mi/kWh EV, charging costs about 4–5 cents per mile — roughly a third of a 30 MPG gas car at $3.50/gal. Heavy public-charging use can shrink the gap significantly.

Industry
Renewable diesel vs. petroleum diesel: how they actually compare
Quick answer: renewable diesel is chemically near-identical to petroleum diesel and works in any diesel engine without modification. It typically cuts lifecycle CO₂ 60–80% and costs about the same at the pump in supportive markets.

Fleet
Route planning to lower fuel spend (without buying another platform)
Quick answer: cut empty miles, fuel in-network on planned stops instead of detours, and use a per-trip planner to validate that "cheaper station" decisions actually save money after the detour fuel burn.

Fuel card discounts, explained: per-gallon, rebates, and the fees you don't see
Quick answer: most fuel card "discounts" are per-gallon rebates off the posted retail price at in-network stations. Out-of-network fuel, transaction fees, and monthly fees can erase the headline number — read the fee schedule.

Fleet
How fleets actually reduce fuel costs (a practical playbook)
Quick answer: most fleets cut fuel costs 8–15% by combining routing discipline, a fuel-card program matched to their network, driver-behavior monitoring, and one honest look at vehicle replacement timing.

Why gas prices change by location (and what you can do about it)
Quick answer: state and local fuel taxes, refinery proximity, fuel-blend rules, brand markup, and station-level competition explain almost all of the price differences you see between neighborhoods and states.

Gas vs. diesel: which costs less to drive?
Quick answer: diesel usually wins on cost per mile for highway-heavy driving over 15,000 mi/yr, but loses for short-trip, urban driving. Run the per-mile math with your own MPG.

How to calculate fuel cost per mile (the number that actually matters)
Quick answer: divide your fuel price per gallon by your vehicle's MPG. That's your cost per mile. Multiply by miles driven to get the spend on any trip.
