Your Home?s Heating & Cooling System And Your Carbon Footprint
Reduce Your Carbon Footprint ? And You Reduce Your Energy Bills
This article describes how your home and its HVAC system contribute to your Personal Carbon Footprint. aIn short, burning fossil-fuels adds to Greenhouse-Emissions, which is what?s causing the Globe to become warmer and warmer.
As the author of this article, I practice what I preach:
- The week I purchased my 1972 built Dallas, TX area home, I had a professional Energy Audit.
- As a result, I upgraded Attic Insulation to R-60, Installed a Radiant Solar-Heat Barrier in the attic (a southern U.S. upgrade), Sealed HVAC Ductwork and Sealed Air Leaks throughout the house.
- I installed a Nest Smart Thermostat
- I am a member of an Electricity Conservation Program through my Electricity Retailer which gives me Real-Time Usage information.
- My Dallas, TX September 2016 Electric Bill was $78.00* ? For an All-Electric Home!
* Note: Dallas, TX daytime highs in September are mid 80?s ? mid 90?s, with an average high of 89.
What Every Individual Can Do To Reduce Global Warming
We hear about Global-Warming and Greenhouse-Emissions in the news?
What we don?t hear much about is:
- How much each individual is contributing to the problem
- How to reduce our Personal Carbon Footprint
Let?s Start With Some Definitions:
Global Warming: Aagradual increase in the overall temperature of the earth?s atmosphere. aIts cause is generally attributed to the Greenhouse Effect.
Greenhouse Effect: aSolar heat-radiation transmitted inward through the earth?saatmosphere,awhile lessaheat-radiationaisatransmitted outward. aThis is due to the build-up ofaGreenhouse Gasesain the atmosphere.a
Greenhouse Gases:
- 82% of Greenhouse Gasses is Carbon Dioxide. a It originates from the burning of fossil fuels, solid waste, trees, wood, and other chemical reactions.
- 9% of Greenhouse Gases is Methane Gas.a aIt comes from landfills, oil & natural gas operations, coal mines and agriculture.
- 6% is Nitrous Oxide. a Itacomes from the use of nitrogen fertilizers, burning fossil fuels, and from some industrial and waste management processes
Carbon Footprint: aThe total amount of greenhouse gases produced to directly and indirectly support human activities.
Personal Carbon Footprint: The emissions caused by 1 individual.a It is a measure of how a person?s lifestyle contributes to climate change.a By shrinking their personal footprint, a person can reduce their effect on the earth?s climate. aReducing your Personal Carbon Footprint reduces your energy bills. aThe larger your carbon footprint ? the higher your energy bills.
Personal Carbon Footprint is broken down into Five Main Categories:
- Housing
- Travel
- Food
- Products
- Services
Global Carbon Footprint Per Individual
A study estimates theaGlobal Average Personal Carbon Footprint = 4.0 t CO2e. aThis means 4 tons of Carbon Dioxide / Greenhouse Gases per person (over a 100 year period).
Note: Personal Footprints are measured based on a period of 100 Years.
United States Carbon Footprint Per Individual
The United States 2005 Average Personal Carbon Footprint = 26.3 Tons
The U.S. Average Carbon Footprint (26.3 Tons) Is Over 6 Times the Global Average (4.0 Tons)!
Of that 26.3 Tons of Greenhouse Gasses Per U.S. Individual:
- 5.2 Tons are generated by our Housing
- 6.5 Tons are from Transportation
- 2.5 Tons are from Food
- 3.0 Tons are from Products
- 2.8 Tons are from Services

How The 2001 U.S. Personal Carbon Footprint Per Individual Compares To Other Countries
The U.S. leads the Globe in Personal Carbon Footprint size
In Japan & France, the Personal Carbon Footprint is less than 1/2 the size of the United States. aKorea?s Carbon Footprint is less than 1/3 of the U.S.
How Do We Each Reduce Our Personal Carbon Footprint?
The two biggest contributors to our Personal Carbon Footprint are Transportation (24.7%) and Housing (19.7%).

The Biggest Opportunity For Energy Savings is You?
This pie-chart above shows:
- What percentage each Structural Component of the home represents. aThe total is 41% of our energy use
- Our Energy Use Behaviors represents 59% of energy usage.a
Percentage of Total Energy Consumption broken down into Specific Areas Of Consumption
Improving Our Energy-Use Behaviors
Our Personal Energy-Use Behaviors Represent 59% of the energy we consume. aBy becoming ?Energy-Use Aware? ? you can lower cooling, heating & water-heating costs ? which also reduces your Personal Carbon Footprint. These 3 areas are the largest users of energy in our homes, representing 1/2 of our entire energy usage in our homes. aBy becoming aware of the areas where large amounts of energy are being used, it becomes easier to lower energy usage.
This article does not make suggestions such as sitting a dark & hot home to save energy. aIt will discuss areas where energy usage can be reduced energy consumption with little to no effect on our personal comfort or lifestyle. aThe recommendations presented here require little effort or money.
Water Heating:
- The Department of Energy recommends your water heater be set to 120 degreesafor most people. aThe factory default setting for most water heaters is 140 degrees. a This change reduces your water heating costs by 14%.
- Add a $15 Water Heater Blanket for a 7.5 ? 15% savings.
- With both recommendations, water heating costs are reduced by up to 29%
- Most laundry does not need hot or warm water to get it clean. aMinimize needless hot water usage by washing clothes in cool or cold water instead.
Buying New Appliances?
- Front-loading washers use much less water. aHigh-Efficiency washers use 15-30 gallons. aStandard-Efficiency Top-Load washers use 30-45 gallons.
- Energy Star dishwashers use 4 gallons of water. aStandard-Efficiency dishwashers use 6 gallons.
Heating & Cooling:
- Checking your furnace filter monthly, and replacing when needed, will reduce your heating & cooling costs by up to 15%
- Flushing the dirt from the fins of your A/C?s outside unit (using a garden hose) will reduce cooling costs by up to 35%
- With both recommendations, you can reduce cooling costs by up to 50%.
If You Are Not Using It ? Turn It Off
This universal statement goes a long way in reducing your personal carbon footprint and lowering your energy bills. aAs you look around your home, you can quickly identify needless electricity use and heat being generated. aPut these items on power-strips and turn them off when not in use. aForming the simple habit of turning things off when not in use is a great start to reducing your carbon footprint.
A 2011 Study by the National Resources Defense Council (NRDC) found that Cable Boxes / DVR comboa foundathe power consumption of athe average cable box/DVR combo of 445,000 watts per year (445 kWh) was higherathe average refrigerator using 415,000 watts per year (415 kWh). a Your A/C must remove up to 1 million BTU?s of heat generated by each cable box each yeara(the number shown was adjusted downward to account for heating months)

A large screen High-Def TV uses 100 watts or a+350 BTU?s of heat per hour. aNot a big deal in winter, but in summer you are more than doubling the cost of running the TV because the A/C must remove the heat the TV generates.
This statement also applies to a coffee maker left on all day to keep the remaining coffee hot. aIf you actually drink the remaining coffee several hours later, it will be quite strong due to the evaporation of the water. aTurn the coffee maker off and reheat the coffee in the microwave. aThat way it will be the same strength as when it was brewed.
TIP: aIf it feels warm when it?s turned on (or off / standby) ? it?s using electricity and adding heat your A/C must remove.
Light Bulbs and Air Conditioning Demand:
Most of us are aware that LED light bulbs use less energy. aThey use 90% less electricity used by incandescent bulbs. aWhat many people don?t consider is how different Light Bulbs produce dramatically different amounts of heat. aAnd your A/C must remove the heat they generate. aYour carbon footprint is increased in two ways with incandescent light bulbs. a1. They use 10 times more electricity. 2. They produce 10 times more heat your A/C must now remove.
- 100 watt incandescent light bulbs generate 341 BTU?s of heat per hour. a a Note: 90% of the electricity used by incandescent bulbs generates heat, not light.
- 100awatt-output LED creates 34 BTU?s per hour
- Running five 100 watt incandescent bulbs produces 1/3 of the heat produced by a portable electric heater (1500 watts) running on high.
Note: a The price of LED bulbs has dropped dramatically due to increased demand. aA major national retailer offers four 60-watt bulbs for under $7.
A comparison of 100 Watt Output LED Bulb and 100 Watt Incandescent Bulb:
- Projected Lifespan a a a a a a a a 50,000 hours a a a a a 12,000 hours
- Watts used per hour a a a a a a a a a a 10 a a a a a a a a a a a a a a a 100

- Heat Produced?50,000 hr a 1,700,000 a BTU a 17,000,000
- LED Bulbs reduce the amount of electricity used by 90%
- LED Bulbs reduce the amount of heat generated by 90%
- Your A/C must run longer to remove the additional heat produced by incandescent light bulbs
- 1 LED bulb will last longer than 4 incandescent bulbs. aThis makes their total purchase-cost roughly the same.
Help Your Refrigerator Keep Its Cool
Your refrigerator must get rid of the heat it produces while running with coils located under it, or on the back of the refrigerator (most are below). a Clean these coils each year (twice a year if you have shedding pets) to ensure your refrigerator runs asaefficiently as possible. aThe dirtier these coil are, the longer the refrigerator must run, and the entire time it?s running it is adding heat to your home. a Cleaning your refrigerator coils once or twice each year will have a notable affect on power bills and your carbon footprint.
a
Managing The Amount Of Time Your Central HVAC System Must Run:
For those who always have people at home, this section won?t likely apply. aFor those who?s home is unoccupied during extended periods of some days, reducing heating and cooling during these times will have a notable affect on both your energy bills and your carbon footprint.
You can save up to 3% on heating and cooling costs for each 1 degree you reduceacooling / heating demand. aIf your home sits empty 9 hours while you are at work, you can reduce your cooling or heating costs by 30% during that period of time by increasing / decreasing the temperature by 10 degrees. a When you return home, you can have the house the temperature you want by installing a Programmable or Smart Thermostat.
Reduce your power bills and your carbon footprint automatically:
- A Programmable Thermostat allows you to select the time you want your HVAC to start running ?ato allow enough time to reach the temperature you want when you arrive home.
- A Smart Thermostat will compute how long it takes to restore the temperatureaand start the HVAC only early enough to reach that temperature.
- A Smart Thermostat uses your home?s WIFI to get the weather forecast. aUsing the forecast + the amount of time the thermostat learned it takes your HVAC to restore the temperature is how the Smart Thermostat minimizes HVAC run-time to only what?s needed.a
The Nest Smart Thermostat Can Also Display The Current Weathera
Either thermostat will reduce the amount of time the HVAC must run. a You will experience no reduced comfort resulting from the savings.

Help Your Clothes Dryer & Fireplace Get Its Breath
A clothes dryeraexhausts about 250 Cubic Feet Per Minute (CFM) of heated / cooled indoor-air from your home. aIf you have a 2,000 square foot home with 8 foot ceilings, you have 16,000 cubic feet of air inside your home. aIt takes your dryer 65 minutes to remove all the air inside the house ? forcing the HVAC system to heat / cool the air the dryer pulled inside through leaks in the home. a Your carbon footprint is at least doubled while your clothes dryer removes heated / air conditioned air from your home.
- Open the window closest to the dryer while it?s running. aThis allows the dryer to use outside air instead of heated / cooled inside-air from your home.
- Minimize clothes dryer operating time by checking frequently to ensure it does not run after clothes are dry.
- Also open a nearby window while your fireplace is burning. aThe fireplace draws 250?350 CFM of heated air from your home.
- Close your fireplace flue as soon as it?s cool enough to touch. aLarge amounts of heat will rise out of your chimney if the damper is left open.
Let The Sunshine In ? In Winter And Close The Blinds In Summer
Here?s a way to get sun-generated heat for free. aSolar Heat contributes nothing to your carbon footprint.
Any window the sun shines through is a source of solar radiant-heat. aIn winter, leave the blinds open to get the benefit of solar-heat. aAs the sun sets, close the blinds to keep heat from radiating outside through the windows. aYou can gather some solar heat without an expensive solar collection-system by managing when the sun can, and cannot shine, through your windows. aUsing renewable resources (solar, wind and water) eliminates any carbon footprint while you are enjoying the benefits of these resources for free.
In summer, keep the blinds closed on windows which have direct sun coming through. aOn windows which don?t have direct sun, the blinds can stay open (this includes most north facing windows).
Add Cellular Shades for better insulating value: a($102 for a 3 x 6 window **)
Improve your home?s appearance, increase privacy options, lower energy bills and reduce your carbon footprint ? all with only 1 purchase.
Cellular Shades shades provide insulating over your windows, reducing heating costs and cooling costs.a Adding tracks along the sides allows for 4-sided insulating ability. aA double-cell, light filtering cellular shade provides R-2.8 insulating value, slightly more than a Low-E window (R-2.7).

- Double-Cell, Light Filtering a a a a a a 2.8
- Same shade + tracks on sides a a a a a3.3
- Double-Cell, Blackout a a a a a a a a a a a 4.0

Establish Heating-Season Lifestyle Habits That Reduce Your Energy Bills And Your Carbon Footprint
- Don?t stand an open doorway while talking with someone outside the home. aInvite them in or step outside and close the door.
- Minimize the use of bath vent fans. aaAfter your shower, turn the bath fan on for 5 minutes to remove only the most humid air (which rises to the ceiling). aLet the rest of the heat and humidity move into the home.
- Lock all your windows to ensure the tightest seal.
- If you have storm windows, be sure to close them too.
- Add area rugs where you have bare floors. aA bare floor feels colder in winter. aCover it with a rug to keep the room warmer + make the floor ?feel? warmer on your feet.
- Arrange furniture to minimize seating against outside walls or windows.
- Be sure no furniture or draperies block any heat ducts located in the floor.
- Put on warm clothes while relaxing at home.
- Enjoy hot beverages while you are relaxing.
- Close off some unused rooms and close the vent. aKeep in mind this affects your furnace?s air-flow, so limit closed registers to 2.
- Keep your garage door closed, especially if living space is above it.
During Winter, Make The Best Use Of The Heat Already In The Rooma
Moving heat from the ceiling down into the room is a nearly free source of heat with no contribution to your carbon footprint.
Use your ceiling fan ? blowing UP in winter. aSet your ceiling fan to low speed with it spinning clockwise to move warm air at the ceiling down into the room (moving along the walls). This will also reduce the temperature difference from floor to ceiling. aYou will increase your comfort and reduce your carbon footprint by balancing cold and warm air in the room.
If the air feels much colder near the floor, try a small fan sitting on the floor and blowing up. aThis will help mix the coldest air in the room with the warmest air at the ceiling. aTo avoid a draft, put the fan as far from the seating area as possible.
Use An Electric Space-Heater In the Room You Are Using And Lower The Thermostat Setting
Space heaters provide ample comfort where you are at, while lowering your home?s energy usage (by turning the house thermostat down) and reduce your carbon footprint.
Heating and cooling your home has the most effect on your energy bills and carbon footprint. aBy increasing the temperature of the space you are currently using, you can be comfortable while the rest of the house is at a reduced temperature. aNote: Fuel-Burning space heaters create carbon monoxide and are not safe to use inside your home ? electric heaters create no toxic by-products.
Infrared Heaters will also increase the temperature of objects they are pointed at, giving you an additional source of heat (from the warm furniture). aAdditionally, infrared heaters don?t dry out the air like electric heaters which move air directly over the heating coils. aInfrared Heaters create a heat that is very similar to the sun. aThe heat they produce warms our skin, clothes and other objects, which is how things near an infrared heater warm up.

Use A Portable Air Conditioner To Cool The Space You Are Using & Raise The Thermostat Setting
Just Like space heaters, portable A/C provides ample comfort where you are at, while lowering your home?s energy usage (by turning the house thermostat up and reduce your carbon footprint.
Just like portable space-heaters, portable air conditioners are also available. aThe come with 1 or 2 hoses (buy the 2-house version, as it uses outside air to cool itself, versus pulling indoor-air from the home). aThey can be temporarily vented through a window or a permanent installation through a wall . aYou can have the room you are using at a comfortable temperature, while the balance of the house is set to a warmer temperature in summer. a By using a portable A/C, you remain completely comfortable while reducing your carbon footprint and energy bills.
The price for this unit varies greatly. aAt the time of this article?s writing, prices for the portable A/C shown ranged from $399 (Sears) to $650 (Best Buy). aIt?s easy to shop for the best price with a Google search.
Portable Air Conditioner
This YouTube Video demonstrates the installation and use of a leading brand of portable A/C. aThis brand also comes in a heat-pump version which can make heat in the winter. aThe heat-pump version is only effective in mild winter climates.
Are You Cooling The Entire House At Night While Using Only 1 Bedroom?
Cooling only 1 bedroom at night with a window a/c (with house thermostat turned higher) will keep you comfortable with far less energy use and notably reduced carbon footprint.
If you are using only 1 room at night. aSet your central a/c to 80 and cool only the bedroom with a Window A/C. aAn Energy Star rated 8,000 BTU window a/c uses about 800 watts to cool only the bedroom. aA 3-Ton Central A/C uses 4.5 times as much electricity (3,600 watts) to cool the entire house (up to 2,000 square feet). aThere are very few things you can do which will reduce your carbon footprint and energy bills as much as this one thing.
The a/c costs as little as $175 and will pay for itself (in Dallas) in one summer.
SUMMARY:
This article focused on Managing Energy Use + Reducing Your Carbon-Footprint with Lifestyle Habits. aA secondary focus was to demonstrate how your A/C more than doubles the energy usage of anything that produces heat. aIt?s easy to realize a 100 Watt-Output LED Light Bulb uses only 10% of the electricity of an incandescent bulb, but your savings more than doubles because LED produces onlya10% of the heat an incandescent light bulb produces. aOnce the heat is generated, you must also pay for your A/C to remove it.
Establishing new Energy-Usage Awareness Habits can reduce your energy usage without affecting your personal comfort and quality of life. aThe primary focus for Energy-Usage Awareness is Cooling, Heating and Water Heating ? while being mindful that anything producing heat makes your A/C run more.
