EFFICIENCY OF ENERGY USE IN THE UNITED STATES

THREE USES OF ENERGY ARE DESCRIBED FOR WHICH GREATER EFFICIENCY IS FEASIBLE: TRANSPORTATION, SPACE HEATING, AND AIR CONDITIONING. SHIFTS TO LESS ENERGY INTENSIVE TRANSPORTATION MODES COULD SUBSTANTIALLY REDUCE ENERGY CONSUMPTION. FREIGHT TRANSPORT INTERCITY BY RAIL AND PASSENGER TRANSPORT INTRACITY BY BUS ARE SHOWN TO BE THE MOST ENERGY EFFICIENT MODES OF TRANSPORTATION. THE HYPOTHETICAL TRANSPORTATION SCENARIO DESCRIBED HERE RESULTS IN A 22% SAVINGS IN ENERGY FOR TRANSPORTATION IN 1970, A SAVINGS OF 2800 TRILLION BTU. TO THE HOMEOWNER, INCREASING THE AMOUNT OF BUILDING INSULATION AND, IN SOME CASES, ADDING STORM WINDOWS WOULD REDUCE ENERGY CONSUMPTION AND PROVIDE MONETARY SAVINGS. IF ALL HOMES IN 1970 HAD THE "ECONOMIC OPTIMUM" AMOUNT OF INSULATION, ENERGY CONSUMPTION FOR RESIDENTIAL HEATING WOULD HAVE BEEN 42% LESS THAN IF THE HOMES WERE INSULATED TO MEET THE PRE-1971 FHA STANDARDS, A SAVINGS OF 3100 TRILLION BTU. INCREASED UTILIZATION OF ENERGY-EFFICIENT AIR CONDITIONERS AND OF BUILDING INSULATION WOULD PROVIDE SIGNIFICANT ENERGY SAVINGS AND HELP TO REDUCE PEAK POWER DEMANDS DURING THE SUMMER. A 67% INCREASE IN ENERGY EFFICIENCY FOR ROOM AIR CONDITIONERS WOULD HAVE SAVED 15.8 BILLION KILOWATT-HOURS IN 1970. INCREASES IN THE EFFICIENCY OF ENERGY USE WOULD PROVIDE DESIRED END RESULTS WITH SMALLER ENERGY INPUTS. SUCH MEASURES WILL NOT REDUCE THE LEVEL OF ENERGY CONSUMPTION, BUT THEY COULD SLOW ENERGY GROWTH RATES.
