Have fun with those numbers.

Did you notice my 2013 monthly average was over $300 less than 2012.
Did you notice that 2013 was the lowest average in the last 5 years.
Prior to 2013 I was using incand., CFL, and fluorescent tubes.
I still have 8 4 ft tubes and 2 2 footers. The rest is LED.
I saved exactly $468 last year. Enough to buy 46 more LEDs @10 per.

Garbage in garbage out.
To many variables.
Heat and air conditioning used, hot water heater use.
More or less overnight company, Etc.
No saying you didn't use less for lighting, I just don't think you can
quantify it using overall electric usage.

How else would you do it?

According to the U.S. Energy Information Administration, 13 percent of
residential electrical energy use is for lighting.

The same agency states that the US average monthly bill for residential
electricity for June, July and August of 2013 was $395. Seems a
little high to me, but again, it's the average for the whole nation.

So, assuming those numbers are close, 13 percent of $395 is $51.25.

Switching to LED lighting that consumes a fraction of the power would
have a serious impact on that cost. So, Hank's numbers don't sound
totally out of the ballpark.

That would make an 11.6% reduction in the amount of residential
electricity used. I assumed the algore lights use 10% of the old style.
That may be to low.
That's an extra $550 a year in your pocket.
