” The most significant way in which humans waste energy is in the form of heat. In North America, nearly half of the energy produced is released from our products, processes and buildings, directly into the atmosphere and the water system. Waste heat recovery is the process of harnessing this thermal energy and re-using it. I have chosen to photograph heating, ventilation and air conditioning units and to use the effect of thermal imagery in order to portray their huge potential for heat recovery. Estimates state that in the U.S., waste heat recovery has the potential to satisfy forty percent of total energy requirements. Operating at this level would save the American economy roughly 150 billion dollars per year and would, simultaneously, decrease greenhouse gas emissions by twenty percent; the equivalent of taking every passenger vehicle off of the road.” – Oliver Pauk
