There are many oil-fired generating plants in the US.
You know the book Cultural Literacy?
You might think about picking up a copy...
Thanks for the tip. when I learn to read, I'll get it.
Seems to me an "oil-fired generating plant" would produce a set amount of electricity and be regulated downstream, much like an electrical system that runs of a generator, etc. They have things called "voltage regulators".
I do not think changing a light bulb will reduce amount of petrol used by a plant, but if I get that literacy book, I'll look into it further. It seems it would only change the kWh's used by that bulb. Not sure what BPA uses in Vancouver, WA for fueling their large turbines, but the turbines run at a constant speed which would equate to constant amount of fuel, whether it has one or two bulbs feeding off it. So thats what had me questioning that bimbos reasoning.
