Industrial customers’ facilities and equipment use electricity for processing, producing, or assembling goods. Overall, this sector uses a third of the nation’s electricity. More than half of the electricity used in manufacturing goes to power various motors. Other sizable uses include lighting and heating, cooling, ventilation, and electro-chemical processes in which electricity is used to cause a chemical transformation. Electricity use in the industrial sector tends not to fluctuate through the day or year, manufacturing facilities operate around the clock so they can’t afford energy sources that don’t produce a steady enough supply of energy, like wind turbines and solar panels. Reliability is everything.
