keeping computers, TVs and other electronics plugged in uses a surprising amount of electricity. We put surge protecters on all these and switch them off when we are done. Also, unplug what you can.

I've been considering making solar blinds. If you go to a fabric store, they have instructions. Essentially, in the middle of the blind is a thermal layer that blocks heat loss and you seal them to the window with velcro so you don't lose heat that way. We have many windows, so I'm going to start on a few and see how hard it is to make these. You can find discounted fabrics various places so it's much cheaper than in fabric stores.
