Responding to the 1973 energy crisis, O. D. Hungerford advised J. Irwin Miller to lower temperature in the house, carpool, and reduce use of Cummins airplanes. Hungerford adds that adopting some of these measures both will show Miller’s conservation of energy and set an example for neighbors and business associates.
