Elizabeth and I changed our most-used lights from incandescent bulbs to LED bulbs about a year ago.

We were averaging a bill of about $90, and a usage of about 470 kWh per month.

Since the switch, we've been averaging a bill of about $60, and a usage of about 380 kWh per month.

That's a total savings, since the switch, of about $360. The LED bulbs cost $260 when I bought them.

Over the summer I added gaskets to all of our outlets and light switches throughout the house. I also improved the garage door weather seal. Both of these measures cost a combined total of $50. We have the Nest downstairs, and the NetAtmo upstairs.

Even in this cold snap over the last few days, the temperature difference between upstairs and downstairs has stayed around 5 or 6 degrees. Last winter, and even over the summer, this temperature difference was usually 9 to 11 degrees.
