Consider replacing old light blubs with compact fluorescent lamp (CLF) light blubs. Not only do they last at least 16 times longer but they use about 75% less energy than a standard incandescent light bulb!
Invest in a low flow model shower head that uses less water. This could potentially save you about $100 a year and it uses half the amout of water than a normal shower head uses.
Turn off and unplug! Try plugging your appliances into a smart power strip so when you turn the strip off, you will be turning off the various appliances plugged in. Turn off your lights as you leave the room. We hear this all of the time but it’s a simple and easy way to save money and energy.
