A while back, National Geographic put out a great guide with 10 steps to cutting the excess carbon out of your life.

Weight control and health tend to go hand in hand—and what’s true for our waistlines also holds true when it comes to the weight of the greenhouse gas carbon dioxide (CO2) and the health of the planet. Excess pounds of carbon dioxide are raising the earth’s temperature and putting coastlines, not waistlines, at risk. Yet for a lot of people, the idea of going on a carbon diet to reduce pounds, much less tons, of the stuff seems airy when there’s nothing to hold onto.

Think of pounds of CO2 as inflated balloons: One pound of CO2 would fill a balloon about two and a half feet wide, and the amount of energy each of us uses every day, just to power our homes and drive our cars, would fill 47 of them. Imagine that for each member of your family 47 of those balloons are added to your home each day. In a week, a family of four would pack in 1,316 balloons, in a month 5,703, and in a year 68,432—enough to fill a building nine stories tall and 100 feet on each side. You wouldn’t be able to find your house in it. It’s no wonder we’re smothering our planet in greenhouse gases. The more balloons of CO2 in the air, the more heat they trap in our atmosphere. So here’s a 10-step carbon diet—a program to keep the greenhouse gas out of 142 balloons every week.

1. Wash your clothes in cold water instead of hot.

Start with something easy. Washing machines produce over 500 pounds of CO2 a year when run on hot water. But your clothes will be just as clean and may even last longer when laundered in cold water.

2. Use a drying rack.

Dryers produce about 1,450 pounds of CO2 per year and the high heat damages fabric. So get more life out of your garments, lower your electric bill and spare the planet by drying at least half of your clothes on a rack or line. Plus, sunlight is the most effective stain-remover around.

3. Seal and weatherstrip your home.

This summer, sealing your home will ensure you don’t lose the cool air you’re paying for. Caulking and weatherstripping doors, windows and any cracks or openings in walls will save about 225 pounds of CO2 per season to run your AC. It pays off even more in the winter when you need to trap the heat; every year, you save 640 pounds of CO2 if you have natural gas heat and 470 pounds if you have electric heat.

4. Insulate.

Insulating your home is a bit more demanding and best handled professionally. There are a number of insulating options better than fiberglass, which presents a breathing hazard from airborne glass particles and formaldehyde released during installation. Some green-building specialists claim that spray foam insulation is the most efficient and cost-effective variety, even though it’s usually composed of petroleum-based polyurethane. If you choose spray foam, consider a blend that includes soybean oil, such as BioBase501, to reduce the reliance on fossil fuels. Another alternative, recycled denim insulation, uses a more eco-friendly material but isn’t as efficient an insulator as polyurethane foam.

5. Wrap your water heater and turn down the temperature.

Insulating your water heater with a simple DIY kit, available at most hardware stores for $20, will save you 300 pounds of CO2 annually. As water heaters can account for up to 13 percent of your utility bill, set the temperature to 120° F. Turning it down from 140° F will save 479 pounds of CO2 annually. If you’re really up for a renovation and it makes sense for your household needs, switch from a conventional water heater to an on-demand heater.

6. Run the dishwasher only when full.
• • • • • • • • • • • • • • • • •

Wait until you fill your dishwasher before turning it on and always set it to the energy saver mode.

7. Turn off your TV, DVD player, computer and cable box.
• • • • •
Burst balloons: 5 per week
Even while idling in “standby” mode, your home entertainment center and computer consume energy. Plug them into a power strip and turn it off after you shut down your electronics.

8. Clean your refrigerator.
• • • • • • • • • • • • • • •
Burst balloons: 15 per week
Take a look at the top of your fridge—cluttered much? Clear it off. Those piled-up plastic containers and cereal boxes can prevent your fridge from venting heat effectively. Then go for the more demanding project: Remove the grill at the base of the fridge (or turn the fridge around) to clean the coils.

9. Compost Your Food Scraps.
• • • • •
Burst balloons: 5 per week
Food waste stored in airless landfills is eaten by bacteria that release massive amounts of methane, a gas 21 times more heat-trapping than CO2. Composting ten pounds of food a week will keep five balloons out of the air.

10. Take the bus or ride your bike.
• • •
Burst balloons: 3 per week (bus), 12 per week (bike)
The average 12-mile commute to work produces roughly 12 pounds of CO2 (depending on your mileage, you produce one pound of CO2 for every mile driven). Even diesel buses are greener than cars when you factor in the number of passengers on board. Give the bus a shot once a week for a year. Or give your legs and heart a workout by commuting on a bike and save even more.

To sum it all up, after a year of these efforts, you’ll have kept over 7,000 balloons of CO2 from entering the atmosphere. That’s about 3.5 tons of CO2 off the average carbon footprint.

Bathroom Water Conservation Tips

It’s never been more important to be wise about water, as it’s quickly becoming a scarce resource. Bathrooms account for over 60% of the average household’s indoor water use and over 1,300 pounds of greenhouse gas emissions from hot water heating. According to the EPA, if every U.S. household installed one low-flow sink faucet or aerator, it would save more than 60 billion gallons of water annually. Here are some easy tips on water conservation:

Install Faucet Aerators on Bathroom Sinks
When installed, each aerator will save 500-2,000 gallons of water a year.

Toilet Leak Detection
Use toilet dye strips to detect leaks that may be wasting over 200 gallons of water a day.

Toilet Water Flow
If you have an older toilet (built before 1980), you could be wasting up to 5 gallons of water every time you flush, compared to modern low-flow toilets. To check the date of your toilet, lift up the lid on the tank. The date is normally stamped on the underside of the lid.

You can reduce water usage on older toilets by adding a filled 1-liter bottle in the toilet tank. This will reduce typical water consumption by 500 gallons per toilet per year.

Brushing Teeth
Turn off the faucet while brushing your teeth to save more than 1,200 gallons of water a year.

Shaving
Turn off the water while shaving. Fill the bottom of the sink with a few inches of water to rinse your razor, rather than running the tap and save about 1,000 gallons of water a year.

Shower Time
If you reduce your average shower time from 10 minutes to 5, you can save more than 4,200 gallons of water each year and cut your utility bills. You would also eliminate an extra 300 pounds of CO2 emissions just from the energy used to heat the water.

Low-Flow Showerhead
Standard showerheads made before 1994 use about twice the water used by newer, energy-efficient models. Maintaining ample water pressure, the most efficient showerheads use as little as 1.5 gallons of water per minute, saving 7,300 gallons of water and $30 to $100 a year, compared to 2.5 gpm models.

To check whether you can save money with a low-flow showerhead, check your current showerhead’s flow rate which may be written directly on it. Another way to check the flow is to hold an empty half-gallon milk carton under your showerhead, turn on the water and use a clock to time how long it takes to fill the carton. If it takes less than ten seconds to fill it, you should consider changing the showerhead to a more efficient model. Look for models with the EPA’s WaterSense label.

Give your Fridge an Efficiency Boost

Do you need an new fridge?
Refrigerators built before 1993 use twice the energy as any of today’s Energy Star refrigerators. The back-up fridge in your basement or garage may be the largest electricity user in your home and your biggest savings opportunity.

If your refrigerator is more than 10 years old, it may be so inefficient that a new Energy Star refrigerator could pay for itself in energy savings in just a few years. When shopping around, keep in mind that side-by-side refrigerator-freezer models use about 7 to 13 percent more electricity than freezer-on-top or on-bottom models.

Refrigerator Efficiency Tips:

  • Refrigerator Positioning – To maximize the efficiency of your refrigerator, position the unit away from heat sources such as ovens, dishwashers, and windows with direct sunlight. Allow at least two inches of clearance around the unit for good air circulation.
  • Door Seals – The rubber door seals on your refrigerator and freezer seal the cold air inside. If they are worn out, the compressor has to work harder to maintain the proper temperature. You can check whether your refrigerator door seals are in good working order by placing a bright flashlight inside the refrigerator. Direct the flashlight toward a section of the door seal, close the door and darken the room. If you see an light shining through the cracks, you may need to have the seals replaced. Be sure to reposition the flashlight to check the entire length of the seal.
  • Clean the Coils – A refrigerator coil brush should be used to clean the coils every 6 months so they don’t have to work as hard to dissipate heat from the fridge. Don’t forget to unplug the refrigerator before cleaning.

Fast Facts from Energy Star:

  • A pre-1993 fridge costs $110 per year in electricity.
  • U.S. households have 44.5 million fridges over 10 years old, 12.7 million of which are secondary units, often in basements and garages. And some homes have three fridges!
  • 16.9 million household freezers are over 10 years old – that’s 44 percent of all freezers.
  • Combined, the inefficient appliances above use $4.9 billion per year in energy costs.
  • New ENERGY STAR qualified refrigerators must be at least 20 percent more energy efficient than the minimum federal standard. New ENERGY STAR qualified freezers must be at least 10 percent more efficient than the minimum federal standard.
  • Every step we take to become more energy efficient and lessen our impact on global climate change is a step to preserve energy resources and our environment for generations to come. Just think: if every American home replaced its old refrigerators and freezers with ENERGY STAR qualified models, together, we would save…

    • * Enough energy to light more than 8.3 million homes for an entire year.
    * Nearly $1.8 billion in annual energy costs.
    * Annual greenhouse gases emissions equivalent to that of nearly 2.1 million cars, or nearly 1% of all registered automobiles in the United States. That is more than the number of registered autos in the entire state of Connecticut. Lined up bumper to bumper, those cars would stretch from New York to Los Angeles and back.

The Progress of PACE

PACE (Property Assessed Clean Energy) financing programs are expanding rapidly throughout the country. By the end of the year, 11 counties in California alone will have a PACE program. According to industry expert and Recurve founder Matt Golden, that means 60% of Californians will be living in a PACE district.

As a reminder, a PACE bond is a bond where the proceeds are lent to commercial and residential property owners to finance energy retrofits (efficiency measures and small renewable energy systems) and who then repay their loans over 20 years via an annual assessment on their property tax bill. PACE bonds can be issued by municipal financing districts or finance companies and the proceeds can be typically used to retrofit both commercial and residential properties.

The advantages of PACE programs include significant job creation, reduction in greenhouse gas emissions, lower energy bills and substantially reduced upfront cost for energy improvements, increase in property value, improved return on investment, and many more.
