"Glad to be with you. My name is Spence, and this is Jeannine, and we're with Account Teams in Salt Lake City, and we help people with their books and accounting and taxes, and all those other things they never like to do. I want to talk to you today about efficiency ratio. This can be related to mainly physical items which you may have or buy. A good example; your furnace goes out, and you look at furnaces and they all have different efficiency ratios. And one says eighty eight percent efficient; one says ninety four percent efficient. What that really means is if you have so much gas going into your furnace and that gas has so much heat value how much do you really get out of that into your home? Well, a good ninety two percent efficient unit would have ninety two percent of all available heat going into their home. The rest would go up in the exhaust gases going up into the atmosphere from the burning. When you're analyzing a piece of equipment, like you're buying an electric motor, they all have efficiency ratios listed on the nameplate of the motor, and you'll find out the higher efficiency motors require less electricity to produce the ten horsepower and the lower ones require more electricity, so you have to evaluate the cost of the motor compared to the cost of putting electricity into the motor with that efficiency ratio."
