Frugal and Energy Efficient Living

I'll have to let my dad know...when I was living with my parents last year (while my duplex was being built and behind schedule) my dad wouldn't let me keep my van plugged in overnight (no timer) because he was concerned about his hydro bill...he plugged it in when he went to work, which meant only an hour before I had to go to school. He cited the high cost of electricity. Well, my battery ended up dead after a long cold snap and he bought me a new battery for Christmas, LOL, so it probably cost him more in the end. Now that I'm in my own house, I keep it plugged in if it gets even a little bit cold and it fires up much better. I may need to look into one of those car warmers. I actually leave it plugged in overnight. I find 3 hours to not be long enough when it gets down to the -25 to -35 range. When I keep it plugged in, I have no issues at all. My electricity bill last month, including Christmas and plugging in the van was lower than in summer when I run a window a/c by half. So, gonna keep plugging in the car! lol.
