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%.

As a follow-through, I have put some effort into finding how electricity
consumption breaks down nationwide in the USA.

Several minutes with Google gives me best leads being DOE web pages
showing such a breakdown only for residential electricity consumption.

Commercial/industrial electricity consumption breakdown percentages
appears to me to be much higher for air conditioning, slightly higher for
lighting (only slightly because the lighting is a lot more efficient),
higher but still low percentages for computers and elevators, and lower
for purposes that tend to be residential ones such as TVs, audio/stereo
systems, water heating, clothes drying, cooking, and electric
cosmetic/beauty products such as hair dryers.
