I wonder if this “enlightened” congresswoman has heard about THERMODYNAMICS.

I'm sorry. I don't understand what you mean by this.

She is complaining that 90% of a light bulbs energy is lost due to heat. But in any system primarily one where you have a filament burning at 1000s of degrees Celsius, you will have a majority of the energy lost to heat and not converted to light.
