I would love to get some solar panels
but, all my windows are west facing and I don't actually see much sky because of all the trees. Not a bad thing since it keeps the place cooler in the summer than it otherwise would be. I'll look in to blocking windows. Currently I just keep all the blinds shut during the heat of the day and open everything at night for some 'free ac'. Not that it gets all that hot where I live, but I prefer cooler temps. I do the same in the winter to reduce heat loss. A better blocker than blinds certainly must exist!
I think getting my girlfriend to buy in to the whole energy saving thing would go a long way as well. She likes to roll her eyes and call me gross when it's yellow and I let it mellow
