I did a little $5 upgrade today... Insulation in the outlets in the external walls, then plugging them with child safety plugs.

We signed with Tesla to install a baby, 3.66kW solar system. It's not much compared to some of you but we don't use much electricity. That should cover 80% of our usage.
The cost is ~$11,200 before tax credits ($3.06/W). Considering the tax credit and the included Google Nest, the cost drops to $2.10/W. That's a good price, I think. The local electric rate is ~$11¢/kWh. The payback period will be about 15 years... Not great, but good enough, and I'm happy to support Tesla. I'll post pics when it's installed.
