Turn the temperature down on the hot water heater from hot to medium. This water is hot enough for dishes and showers. If you need it hotter for a bath or something else, turn it up beforehand and down when you're done. Just a few extra steps like that can save money and natural resources. For those of you who cook with propane or natural gas, save money with a stove that has an electronic ignition instead of pilot lights.
Pilots waste gas and add heat to the room in summer that then needs to be cooled.
An electronic ignition uses very little energy in relation to the amount of gas wasted by pilot lights. To save on your heating bill, turn down your thermostat. This will actually have dual benefits. Too many people have very warm houses, which can make you ill. The cooler your house is, the healthier you will stay.
