The National Resource Defense Council (NRDC) issued a report this October that America had used the same amount of energy (measured in BTU’s) as it had used in 1999. We have reduced our energy usage per person, while still growing the economy, a feat that I would not have thought possible.
You can read the full report here: NRDC Energy Report. So often environmental news is dire and gloomy, but this news shows the power of energy efficiency. As noted in the report, politicians and media members focus on where we are going to find new energy resources. As opposed to opening up new energy reserves, we have reaped larger rewards from spending time and money conserving the energy over the last thirty-five years. The energy report uses the household refrigerator as an example of an appliance, whose increasing energy efficiency greatly decreased our electrical load per person. Refrigerators use 1/4 as much energy as the same size refrigerator used in 1975. This decrease in energy usage is a huge gain for the user who replaces their refrigerator and for the power grid that doesn’t need to build a new power plant to keep up with the increased load. 
As an EXAIR employee, I can not help but notice that EXAIR opened in 1982, which is one of the first years in the graph above were economic growth was not directly tied to energy usage. At EXAIR, we realize the impact of conserving compressed air can have on your compressed air system. By replacing home-made blow offs like open tubes or holes drilled in pipe with Super Air Nozzle or Super Air Knife engineered solutions, you conserve compressed air and save money. This also reduces wear on the your compressor and can extend its life. A model 1100 Super air nozzle uses 14 SCFM when fed with 80 PSIG, which is a 58% reduction from 1/4″ open copper tube, which uses 33 SCFM when fed with 80 PSIG. Go to our Air Savings Calculator to see how much compressed air and money you can save by replacing those home made blow offs.
