What do you think of when you hear the phrase, “energy efficiency?” Compact fluorescent (CFL) lighting? Maybe Energy Star appliances or adding insulation to your attic.
What all of these things have in common is that they are all residential solutions, but despite their greater numbers residential customers use far less electricity than do commercial and industrial customers. Certain industries (e.g. cement, steel, aluminum) use enormous amounts of power, but the efficiency conversation rarely touches on these users.
That’s unfortunate because industry is where the big potential savings are. Consider that while all lighting (residential, commercial, industrial combined) accounts for around 5.5 percent of total electricity consumption, electric motors in industrial applications alone use nearly five times as much, fully 25 percent of all electricity consumption.
