If you don't have 100% Green Power or your own solar cells for electricity, there are some surprising electricity eaters in your home that can really add up to a lot of energy usage and increasing your negative impact on the planet. Toning down use of these appliances might save you some cash, and reduce your "brown" footprint.
Everybody knows about Air Conditioning and that power drain -- but did you realize that there are some other major power gluttons lurking?
(Some of this discussion might not apply to a house with 100% Green Power -- if you have solar cells running your electric dryer, then you avoid the fossil fuels entirely. Huzzah!)
HOT HOT HOT: Coffee Maker / Water Heater / Dryer
An electric coffee maker uses a tremendous amount of electricity. The heating element to heat the water draws heavily, but so does the electric hotplate built into the thing, which may run (even in an "auto off" coffeemaker) for several hours.
Our pretty plain Mr. Coffee coffee maker is rated at 900 watts. If it runs for 2 hours, that's 1,800 watt hours, or 1.8 kWh (kilowatt hour) of power. Since the whole house uses between 12-14 kWh in a 24 hour period, you can see how that adds up. Thirty days of two hours of coffee maker use per day, on average, adds up to 54 kWh, enough electricity to run our entire home for four days!
The high-juice draw is true of any heating function performed by electricity. Stove, space heater, water heater, clothes dryer, hair dryer, oven -- even microwave ovens draw tremendous wattage for the time they are in use.
In addition, electrical heat is terribly inefficient in terms of resources these days. Once upon a time, the "Gold Medallion All Electric Home" was touted as the latest and greatest, but that was before we realized we needed to get the most efficiency out of every scrap of fossil fuel.
NOT NOT NOT: Thermal Inefficiency
Fire is still more thermally efficient for heating than overloading an electrical wire to make it glow to produce heat. In addition, a gas dryer and water heater use the energy in the gas directly to make heat, electrical devices use gas at a power plant to make heat, which is then used to generate electricity, which is then used to make heat again -- each step in the process loses efficiency and wastes the available energy.
So, if you can afford it, and already have 100% Green Power or are on Solar or Wind at home, electricity is a fine choice. But if, like most people, you can't afford to waste energy due to the cost, or don't want to leave a dead brown planet for your children, then it is an Easy Green thing to do to monitor, limit, and maybe even eliminate some of these electrical uses in your home.
Now where did I put that non-electric drip coffee maker?
