Using Traditional Light bulbs: If you still have incandescent light bulbs in your home, you could be throwing a lot of money away every month on inflated electric bills. Over its lifespan, an incandescent bulb can use $180 worth of electricity. A CFL will only use $41 worth of electricity over the same time period. Even better is the LED bulb, which only uses $30 per bulb.
Ignoring a Leaky Faucet: A leaky faucet that drips one drop per second can waste more than 3,000 gallons per year, which is enough water to take more than 180 showers. Some of us live in areas where water is plentiful, but for those of us in areas plagued with drought, this could be costing you a fortune. Fix or replace your leaky faucet and save a ton on your water bill.
Not Customizing Temperature: Invest in a customizable thermostat. If you are away at the office all day, you can program your heater to shift down a few degrees while you are gone and then shift back up shortly before you return home. Heating or cooling an empty home wastes a lot of money in energy costs.
Water Heater Temperature Set Too High: Unless you have a tankless water heater, your water heater is keeping the water in its tank hot 24/7. Decrease the temperature in the summer, and bump it back up when winter comes. ***
