The National Electrical Manufacturers Association (NEMA) managed to help themselves to a slice of pork. First they created a marketing concept, "NEMA Premium" electric motors, which are supposed to be radically more efficient than "NEMA Standard" motors. Naturally NEMA Premium motors cost more than NEMA premium. Then they got a US government subsidy for the purchase of "NEMA Premium" motors as an energy saving measure.
Trouble is, electric motors are highly efficient already, and motors manufacured 50 years ago are very efficient. The "Premium" motors are not any more efficient than any well designed motor. "Premium" motors run between 77 and 89 percent efficient. In actual fact, decent electric motors have been 90 percent efficient since World War II and before.
In short, a marketing concept, the "Premium" designation, has been recognized at law, and given a federal subsidy, paid for with tax payer dollars.
Nice work if you can get it.
This global warming measure was brought to you by congressmen from districts with large electric motor companies.
