Nine no-cost ways to reduce your home energy use

Cher Seruto is an analyst with the Built Environment Team at the Rocky Mountain Institute.

There's a crispness to the air, and winter is again upon us. Colder temperatures and longer nights bring more frequent indoor gatherings with family and friends. But, if you're anything like me, you're having trouble socializing because you're anticipating a spike in your energy bills.

The average American household spends about $1,900 annually on energy and also creates more than 26,000 pounds of carbon dioxide per year. Collectively, residential energy use accounts for about 20 percent of the country's greenhouse gas emissions.

We all want to be warm this season, and we often don't mind the increased cost. In fact, some of us may view those increased energy costs in the winter as a necessary evil.

But what if you had some no-cost, quick and easy ways to reduce that energy bill while saving the environment and maintaining the same level of comfort?

Well, here you go.

The Rocky Mountain Institute recently compiled energy usage information for the typical American home. In the process, we found dozens of ways ordinary people can cost-effectively reduce carbon dioxide emissions from their own homes.

These nine suggestions cost nothing and will save you money:

  CO2 Saved (lbs/year) $ Saved ($/year)
Lower water heater temperature to 120°F 214 $12.12
Lower thermostat in winter by 2°F 353 $19.04
Wash clothes in cold water 327 $18.58
Turn off unneeded lights 376 $21.04
Turn off home-office equipment 137 $7.68
Unplug extra fridge in garage 448 $25.04
Use energy-saving mode on appliances 769 $43.04
Increase AC thermostat by 3°F 339 $18.90
Air dry clothes during summer 779 $43.60
TOTAL SAVED PER YEAR: 3,742 $209.04

Not only can these free tricks save the average household more than $200 a year in energy costs, but the carbon dioxide reductions are equivalent to taking 10 miles off of your daily commute.

So be a do-gooder this season and year round, keep your guests happy, and give your pocketbook a boost, too.

Also, stay tuned, because next week we'll provide further energy efficiency measures you can purchase for less than 20 bucks per ton of saved carbon.

    I so agree with many of these comments. The little things don't make much difference, and in terms of comfort, I am not going to be cold/hot just to save $20/year. The things I did that greatly decreased my energy bills: a set-back thermostat for each floor, manually setting my dryer to a shorter cycle, buying a new/more energy efficient fridg, closing the door to the upstairs during the day when heat or AC is used.

    I can save you a lot more money.... Here's how. find the thickest blanket you have, wrap your entire family in it and go live in a card-board box from your neighbor's new tv set... Pleeease... Who the heck writes these commentaries. I bet that he or she isn't even concerned about saving a few bucks.

    Moline Transplant says, "Cars can now run on water..." Is anyone really that gullible? Putting aside the scams you find on the internet, all proven methods for separating hydrogen from water all require more energy than they produce. Windfarms?? You think the problem with windfarms are the aesthetics? Do you ever do any research/thinking before you form an opinion?? The main problem with windfarms are the tremendous cost to build the infrastructure to transmit the power from where the wind blows to where the power is consumed. Secondly, no matter where the windfarms are located, the wind only blows intermittently. You can't power a reliable electric grid based on intermittent, variable power sources. I'm in the power industry - I know first hand. Only 1.6% of the electricity generated in the US comes from oil and that figure is dropping every year. 50% of the electrical generation in the US comes from coal. Coal is cheap - but dirty. Clean coal technologies (syngas and others) are extremely technically challenging and expensive. The best solution is to replace the coal fired generation with natural gas fired combined cycle generation. Although we'll need to increase our gas production and transmission infrastructure, gas is the cheapest solution. Gas is clean. Is it carbon neutral? No - but if you buy into the whole anthropogenic (man made) global warming/green house gas scam, you are so under-informed (once again). Anthropogenic GHG emissions only account for 0.28% of all GHG emissions. Gas fired combined cycle power plants can be located closer to the major load centers to reduce transmission costs, and they can be base loaded to provide consistent and efficient generation. People - get real. Do the research before you open your mouth and demonstrate your ignorance.

    LED lighting can save lots more money, I just purchased some at www.ledbulbs.tk they run on 2 watts and put out the same amount of light.

    I found that unplugging TV, DVD, computer and anything with an LED that is not in use and turning off extra lights easily cut out electric $15.00 a month. The kids were truly impressed. We have always line dried our clothes. We wash in the coolest ater possible and use ALL the energy saving bottons on the dishwasher. The payoff for my kids is that we have saved enough to pay for their state university tuition costs. With them out of the house the water bill went down $20 a month!!!!

    My house faces the south, so in the winter I let the sun shine in the front windows and the kitchen window which faces the east. In the summer I open the back door, to the north which lets in cool air. On sunny days in the winter I also open the garage door into the utility room to let in warmer air, because the garage isn't insulated so the sun heats it up. Last summer I didn't have to turn on my A.C. at all. My electric bill was never over twenty dollars. I do live at 4000 feet altitude though.

    I am all for efficiency and reducing my energy usage - and I have. Personally I am more interested in saving MONEY! But my electric bill goes up every month and kwh's goes down compared with last year. I work for an electric utility and there is a major flaw with the current business model used by electric utilities: They make money by building power plants / generating electricty. When we conserve, the utilities want to be compensated for loss of revenue, which they get approval for from your state utility regulator. So in the end, the consumer who conserves will still have to pay more. It's time to change the system.

    Were the candidates thinking green as they criss-crossed the country how many times (??)to get our votes? Was Gore thinking green when he flew to the summit - are they all downsizing to save energy? I doubt it, but they expect it of us little folk.

    I discovered that I mainly use hot water on the weekends- doing laundry, dishes, taking looong baths. During the week I only hop in the shower for 5 minutes, get ready for work, rinse a few dishes and I'm out the door till night. Why have that water heating, on stand by, all day when nobody uses it? So what I started doing is lowering my hot water tank to "warm" all week and then I turn it up to hot on the weekend. The "warm" water is enough for my shower and I usually use less water because I am not diluting "hot" with additionan cold water to make "warm".

    Just remember,there is just as much money in tearing down an economy as there is in building up one.Follow the money,who's making the money on all this green scare? Al Gore and company.Yes,it is always good to economize,but we have gone crazy in this country and the world.To think we have the capability to change the universe is lunacy.

    Sharqbait - amen to that! I pay some of the highest utility rates in the country (average $0.28/kWh). The utilities are one of the largest barriers to reducing electrical costs. They have absolutely no incentive to do so. They have to grow the rate base in order to increase returns.

    I read everyone of these articles that tell me how to save money now on my electric bill, expecting something GREAT! But it's always the same old thing. I had a home energy audit performed on my house. If I spent $20K plus replacing my windows, doors, HVAC, and adding more insulation in my attic, I would save an estimated $150.00 per year. Not a very good ROI. All the breaks go to the business community. The only improve,ment I did was add insulation to my attic. On another subject, wind turbines only operate 16% on average of all units installed across the country. It won't support base load generation when we need power most. There are (2) plants in the world that operate on compressed air and there is talk about using the power generated by wind turbines to compress air that could be stored in abandoned salt and coal mines, gas pipe lines, etc, and then generate power when we need it most from the stored compressed air. But in my opinion, we need a balnced approach using multiple technolgies to generate (and store electricity), in addition to SERIOUS CONSERVATION efforts, and not be penalized for conserving.

    Duane, Jim and BPugh..... you guys made me laugh. I agree with you. By the time I spend a katrillion dollars on energy saving appliances, a hybrid, solar screens and windows, etc....$200 savings is going to piss me off. If you see me driving in my jallopy giving off a ton of exhaust and fumes don't be mad at me... that jaloppy gives me 150 miles to a gallon!!!! Nah that is savings I can live with!
