There weren't as many of them, but they were tremendously energy
inefficient. Third worlders' lighting today is like <1% efficient,
and lighting accounts for 1/3rd of U.S. electrical usage.

What was the carbon pulse to the atmosphere like
back then?, and maybe they saved us from universal ice?

As it turns out, lighting accounts for a lot less than 1/3 of electric
energy consumption in the USA. I have less tracking of national total
here than of a strong memory for a residential figure that lighting
accounts for about 9% of USA residential electricity consumption.
I suspect that the figure for percentage of USA's residential electric
bills for lighting will be much higher than 9%, since homes in areas with
cheaper hydropower will have more electric heating.

It does appear to me that around 70% of USA electricity consumption is
for motors in refrigeration and climate control devices. Sorry, I will
need to do some work to get a more refined and citable figure.

I now see that my 70% figure just for motors used for refrigeration
and climate control needs a correction. Now it appears to me that
refrigeration, climate control including resistive heating, and water
heaters and clothes dryers add up to 61.5% of USA residential electricity
consumption. Lighting accounts for 8.8%.
