Conserve on your water usage. Living in an apartment can waste a lot of water and that is mainly due to leakage. Keep an eye out for dripping faucets, running toilets and under the sink leaks and let your landlord know about them. Also, if you have a dishwasher, use it but only run it when you have a full load. Washing dishes by hand wastes more water. The same goes for doing your laundry, only run a load if you have enough for a full load. In the bathroom, turn your faucet off while brushing your teeth and only turn it on when needed. Learn more about water conservation in Green Apartment: Water Usage.
