Gas Supplies Total Energy Total energy supplied by na tural gas is becoming a reality for a growinp number of businesses and industries across the United States An experimental concept just a few years ago the idea of providing heating, cooling and power generation from one energy source has proven its feasibility in scores of applications, and today the gas industry is confidently looking ahead to much greater activity in this area. Total energy is now beinij used successfully in such widely diversified locations as shopping centers, schools, industrial plants, motels and general office buildings. The basic principle is simple, las, piped into the building by the conventional method, is used as fuel to drive a turbine or engine, which turns an elec- ric generator. Exhaust heat is used for heating the building in winter, for air conditioning in all seasons, and for heating water. The advatages are many. One is the saving in cost. Total energy installations now in operation have proven that they can provide all needed energy at a much lower cost than is possible with separate supplies of electric power and heat. The first such installation a high school at McAllen, Texas, for example, was placed in operation August 16, 1963. It was estimated that the yearly saving from on-site power generation at the school was $40,000. Another advantage is electrical efficiency. Instead of the standard 60-cycle electric current, a total energy installation generates electricity at a much higher frequency, which means, for example, that flourescent lights use less current for the same amount of light, and run at lower temperatures Another big' advantage is, of course, dependability, since gas pipes are underground and not affected by aboveground disturbances. Gas dependability was dramatically demonstrated during the November, 1965, blackout on the Eastern Seaboard. One of the few cases of light in the general blackness was Rochdale Village, in Queens, New York. Rochdale, the largest cooperative housing project in the world, with 20,000 resi dents, generates its own electric power with generators dri ven by gas. This method wa.« chosen because of the substan tial savings it offers; depend ability proved to be a valuable bonus. Today there are more than 300 gas total energy systems in operation in the United States While the installation costs are i in some cases higher than those for other systems, the fuel savings over just the first few years more than offset this — and from there on the savings are little short of spectacular. And perhaps best of all, light, heat, power, and air conditioning are always there when you need them.
