[USMA:24572] Power

"Half to generate electricity that is only 25 percent
efficient"

It is actually 35 % efficient in old power plants and
50 % in combined cycle gas fired power plants.
So the average efficiency should be somewhere around
40 %.

I think the reports I was quoting that from were talking about the distribution system losses as well so that when the person used a 100 W globe it took 400 W of energy input at the plant to delivery 100 W to the bulb. TThis comes from an Amercian Society of Engineers Report and the US Task Force on Energy

I realize this is off list but why is the US 110 Volts and yet I can get 220 - 240 for the laundry products.
