Betting On Hybrid, Electric Vehicles
For delivery vans, says Smith, FedEx is betting on electric or hybrid vehicles.
"An all-electric pickup and delivery van will operate at a 75 percent less per-mile cost than an internal combustion engine variant," he says. "Now, I didn't say 7 1/2 percent — [I said] 75 percent. These are big numbers."
Smith points out that the vehicles would be charged in off-peak hours, minimizing the need for additional power plants. Battery life and cost remain a challenge, but Smith is optimistic.
Adding Biofuels, Natural Gas To The Mix
For FedEx's fleet of nearly 700 planes, Smith says biofuel, probably produced with algae, will replace much petroleum-based jet fuel. The technology has already been proven, but breakthroughs are needed to produce the fuel on the scale that's necessary.
