I live with roommates, and am only a renter not owner. I'm looking for ways to help with energy conservation despite this. We have one roommate who is wasteful about leaving lights on and, in particular leaving the bathroom window open in a heated house for some reason, and I try to address that. General tips for helping my roommates to save power use are always good.
However, my main concern is in heat. My room is smaller then the rest and as a side effect grows warm much faster. I'm very hot and wake up with a dry throat, and can only think how much energy is being wasted on something I don't want. However, we don't have individual thermostats or any way to close my floor vent; and my roommates don't want to lower the heat since they are comfortable where they are.
Is there a good way for me to divert the heat away from my room, both for my own comfort and for saving energy. The obvious idea would be to cover the vent with a blanket or something, but I think I read this is bad for the heating system as a whole due to the build up of pressure on the closed off vent? Any other tips for diverting the heat? Or convincing the roommates to just lower it.
