Yeah, the cloth grocery bags are a terrific idea (and really help out). They are stronger than the plastic ones (so actually easier to carry stuff in them) and they have handles, yeah. I actually prefer them to plastic bags - but you do need to remember to leave them in the car so they are there when you actually need them.

With respect to the energy saving lightbulbs - they really are pretty good. We have them installed in our hall of residence. I'm not sure about breaking them (I've never heard of anyone breaking them). But I'd imagine they must be pretty safe for them to be installed in a hall of residence?

Another thing is fuel consumption...
