*Each lamp has identical lumens output.
*The LED lasts 10-X the life of the incandescent,so it doesn't cost the consumer a penny more to own and operate it over it's service life.
*The LED uses 1/10th the power for the same lumens output.
*For zero cost,you've increased the generating capacity of the electric provider and provided for nine more families' illumination,without any additional power generation capacity.(negaWatts)
*You've cut carbon emissions by 90% with no sacrifice in illumination.
*You've increased the 'fuel economy' of the lumens by 10X.

All energy consumption can be similarly impacted,across all market activities.
In times of war,all this consumption was simply reduced by War Department edict, enforcement,and market mechanisms.
If you want to go to war against climate change,it's really simple.Dirt simple.Nobody will say it's easy though.
You can't deny it,as we've done it before,twice before.
We can choose to begin,in earnest.Steady,year by year progress.
Concentrate on needs.Put wants on hold until we clear the emergency.
It's what America knows how to do.
Once the storm passes,then we can relax things if we so choose.

We already did many of the electronic efficiency upgrades. Which did result in a slight decoupling of increasing population/ GDP from energy from 1980 to 2010. but much of that is now recoupling. Transportation will be the next big improvement. but you have yet to put your number on what feasible per capita reduction that you can rationally foresee. and keep in mind 3 Billion people still burn wood and dung for all of there cooking and heating needs. They will be the ones who's lifestyles will have to change the least in the next 100 years. All efficiencies have been approximated to allow an improvement of 2:1. Do you really think rebuildables will achieve 8 TW? Before we run out of our fossil fuel seed corn that is required to build them out?
