The US Air Force has developed an energy plan focused on reducing demand and increasing efficiency.

For instance, 99 percent of the Air Force fleet is now certified to operate on a 50/50 blend of synthetic fuel derived from byproducts like feed stock and normal jet fuel.

Operational flight paths of some aircraft have been changed to take advantage of shorter distances to destinations in Asia, which saves not only fuel but also wear and tear on aircraft.

They have instituted periodic washes of the insides of jet engines to remove excess dirt and grime, which makes the engines run cooler and leads to millions fewer gallons of fuel consumed every year.
