Virtually ALL of the savings possible in the national grid with fluorescent lights were attained decades back.

By the time Congress got around to worrying about lightbulbs MOST residential use was in fluorescent lights as well.

The error in your thinking is that residential usage consists of mostly lighting. Actually it's heating, cooling and cooking. Lighting usage is negligible!

Actually, my graph is correct. In the yellow rectangle it is explained...

Of ALL energy used, 4.65% of that goes to ALL residential uses.

Of ALL residential uses, 12% of THAT goes to lighting (which is the red stripe that takes up 12% of the mustard colored pipeline inbound into the Residential block (approximately, I just winged it to get the relative width somewhat the right size)

Does that make sense? It is kind of a hard concept to explain, but I got that 12% of all residential use is lighting number from the Department of Energy website.

To me, well designed graphs are a thing of beauty, and when I saw this one from Lawrence Livermore Labs, I fell in love with it (figuratively speaking)

This one below is my favorite graph of all time, because it shows up to five different data points in a brilliant design that intuitively lets you see all of them at a easily and can be understood at a glance!

It describes Napoleon's advance on and retreat from Moscow...I am amazed every time I look at it. His army was destroyed. Amazing.

He left France and advanced on Moscow with 422,000 men and came back with 10,000. Good God.
