IT’S HOW MEDICINE SHOULD BE ® | SPRING 2011 ENERGY ISSUE • The elevators in the new parking garage at Rush University Medical Center capture the energy released during braking and feed it back into the garage’s electrical grid. • To save energy, sensors in all ofﬁces and staff work areas in the new hospital at Rush will automatically turn off the lights when the room is unoccupied. • An X-ray uses invisible electromagnetic energy beams to produce images of internal tissues, bones and organs. • Energy comes in many forms, including thermal (heat), radiant (light) and kinetic (motion). • In 2007, each person in the United States used the energy equivalent of, on average, 7,759 kilo- grams of oil, while each person in Germany used the equivalent of 4,027 kilograms and each person in India just 529 kilograms. • Acupuncture is based on the concept that the body has its own energy ﬂow, which must stay balanced for good health.
