Energy conservation

• It was over a year living in this apartment before I discovered that the base heater in the bathroom actually has a separate thermostat from the one in the main quarter. That explains why it seemed to retain heat so much better than the rest of the apartment.
• I used to turn my mobile phone off when I'd go to sleep, but then I started relying on it as an alarm clock. However, it uses perhaps less than a tenth the power when I turn its radio (for cellular communication and wifi) off, so now I put it in aeroplane mode before I sleep. Bonus: people can't disturb my sleep, even if it's an emergency.
• My DVD player gets hot if it's off but plugged in. Obviously drawing power, so now I keep it unplugged, along with other devices.
• Alarmed to discover that the seal on my refrigerator door has failed. Contacted landlords. :|
• I don't have air conditioning, so it's not that energy is being conserved, but my comfort is, when I close my curtains to block sunlight from entering my apartment during the warm summer days, which I spend mostly on campus.
