Department of Energy Findings
Compressors use as much as 10% of all electricity generated in the United States. The Department of Energy estimates that as much as half is wasted, with more than 25% of all compressed air lost through leaks (some air audit professionals have found overall leak rates as high as 50%). An additional 15-25% is wasted through artificial demand and inappropriate uses.
Power accounts for 70% of compressed air operating costs. When you consider that just one 100 hp compressor consumes $50,000 in electricity per year* it becomes clear how much you stand to gain by improving compressed air system efficiency.
* Based on full-time operation at the US average cost for industrial electricity of $0.06/kWh.
