3 Years Of Electricity Usage

I just graphed our most recent 3 years of Electricity Usage. We
installed a 24 Panel PhotoVoltaic System (electricity from the sun) with
battery backup 3 years ago.

There are still 2 months left of our one-year usage cycle, but you can
vividly see the effect that compact fluorescent (CF) bulbs had on
electricity usage. Orange line is this year, blue line (with a few data
points missing at the end of the cycle) is 2007

Those CF bulbs work great!

Just do it.
