Lower Your Carbon Footprint in 2011
Positive Energy; Boulder, CO
Are you ready for some good news from the green economy? Thanks to stimulus-funding in support of energy-efficiency, green business owner Diane Merker says she's as busy as she's ever been.
Selling products like low-energy light fixtures, programmable thermostats, insulation against home-heat loss, home-energy monitors, and more, Merker's business, Positive Energy, is a one-stop shop for drastically reducing your home-energy use. Energy efficiency for all of us is the first step toward pulling our greenhouse gas emissions way down, and using energy at a rate compatible with widespread use of renewables. Check out our interview with Diane, and check out her blog, Positively Green, for more information on how to save money and energy with Positive Energy.
Green America: What does your business do?

Diane Merker: I started my company, Positive Energy in 1985 as a bulk-ordering catalog for the 1000 agencies then funded by the Department of Energy (DOE) and Low-Income Energy Assistance Program (LEAP), for purchasing the energy-efficiency products that they installed in low income clients’ homes.
In 1995, I added the online Green Builder’s Catalog (www.positive-energy.com), to sell these same products to the energy-conscious homeowner and contractor. It is hard to believe that just 15 years ago, when I told my mother that I was adding this Web site, she asked, “Why green? Why not another color?” In the time since then, I'm happy to say, “green”, and” energy conservation” have become household words.
What makes your business "green" and what are your most popular products?
Diane: On the Green Builder site, my biggest sellers are low-energy ventilation and whole-house fans. Besides helping the environment, most of the products that I sell also make the home a more comfortable place to be. For instance, besides being low energy users, our fans are super-quiet.
I'm a one-woman operation (with two friends who assist me for a half-day every week, and cover for vacations), and so I control how green my office can be. I use every piece of paper twice, and then recycle. I walk or bike to work every day, and provide bus passes for my two employees. Whatever is shipped from our location goes out in a reused box. I will even admit to cardboard dumpster-diving to find a good box.
What did you do before you started your green business?
Use the "Watt's Up" meter to monitor the electricity usage of your household appliance, and replace the biggest energy hogs. |
Diane: I moved to Colorado in 1981 to study solar energy. When the solar tax credits disappeared a few years later, and the bottom fell out of that industry, I took a job as an energy auditor for a weatherization program. Realizing the need for bulk buying, I started my business. I thought up the name “Positive Energy,” and knew right away that it was the perfect two-word description of what I wanted to be aiming for.
What are some of the challenges of maintaining high standards of social and environmental responsibility?
Diane: I still struggle with questions about every product that I sell – how much energy is used in transporting the products to the customer, what are the labor conditions in the manufacturers factory, etc. I try to work with small US companies with good practices, but this isn’t always easy. I try to have a personal contact with my vendors, so that I know and trust that their values align with mine.
What has been your proudest moment as a green business owner?
Converting your toilet to a dual-flush model with this simple adaptation can save water, energy, and money. |
Diane: Really, in every aspect, I am so glad that I made the decision to start my own business 25 years ago. I am often the moderator for our local Green Building Guild’s monthly meetings. I am always proud to look out at the value-oriented, thoughtful, and committed group that assembles and realize that I am a part of this movement.
What's inspiring you now in the green economy?
Diane: Right now, I am inspired by the additional work for weatherization that the government stimulus package has made possible. More low-income homes being made energy efficient means employment for auditors and installers, lower energy bills for homeowners and a cleaner planet for all of us.
What advice would you give to other green entrepreneurs just starting out?
Diane: Be flexible by staying small would be my advice. I added my Web site for homeowners and private contractors when the government stopped funding the DOE weatherization programs. Don’t think that one bad year means that you have to bag the whole thing. After being in business for 25 years, I look at the big picture and realize that there are years that are better, and years that are not so good. If you have a good idea, and love what you do, stick it out, and things probably will turn around.
What is your next green step for the future?
Diane: I am in the fortunate position right now of being too busy (because of the stimulus package) to think about the next step! I would like to work with private energy auditors to make sure that this good work being done in the public sector has a future in the private sector once stimulus funds disappear.
What green product (besides your own!) could you not live without?
Diane: I love our Renai on demand water heater. We have never had a problem with it, it saves on our water heating bill, and we never run out of hot water.

Water saving with dual flush toilets
I was up in Calgary, Canada for vacation this summer, and was very happy to see all of the energy conservation measures being put to practice in homes, hotels and businesses. One thing that really caught my eye, were the dual flush toilets, which were even evident in the airport. With a dual flush, you pull the lever up for liquid for a half flush, down for solid for a full flush – thus cutting you water usage markedly. Old style toilets use about five gallons per flush, the new low flows use about 1.6 gallons. In either case, this amount can be cut in half most of the time using the dual flush.
Replacing a perfectly good toilet just to have a dual flush seems impractical, and, although our local recycle center, like many others, does accept, and consequently pulverize donated toilets, this still does not seem like an energy conscious move. The solution, a dual flush conversion kit that can change any toilet into a dual flush, even low flows. We now carry this item on our website, www.positive-energy.com, in the water section.
Here is a some info on how dual flush toilets operate, sourced from the “How Stuff Works” website.
The way water is used to remove waste from the bowl has a lot to do with how much water is needed to get the job done. Standard toilets use siphoning action, a method that employs a siphoning tube, to evacuate waste. A high volume of water entering the toilet bowl when the toilet's flushed fills the siphon tube and pulls the waste and water down the drain. When air enters the tube, the siphoning action stops. Dual flush toilets employ a larger trapway (the hole at the bottom of the bowl) and a wash-down flushing design that pushes waste down the drain. Because there's no siphoning action involved, the system needs less water per flush, and the larger diameter trapway makes it easy for waste to exit the bowl. Combined with the savings from using only half-flushes for liquid waste, the dual flush toilet design can save up to 68 percent more water than a conventional low flow toilet [source: Green Building].
The dual flush toilet uses a larger diameter trapway that doesn't clog as often as a conventional toilet, needs less water to flush efficiently and saves more water than a low flow toilet when flushing liquid waste.

For the Energy Auditor
Now here's the rub - Many people who pay for the audit, and get the recommendations that are going to save them big bucks, never follow through by actually making those improvements. Find a good insulation company, HVAC contractor, etc, and then look at your state's list to see if any rebates are being offered on the work that needs to be done. Here's a cool site for seeing what is available:http://74.125.95.132/search?q=cache:iD-PAB85nSQJ:www.energystar.gov/index.cfm%3Ffuseaction%3D
For all of you energy auditors out there, we have just added a section on "Energy Auditing Tools" http://www.positive-energy.com/energy-auditing-tools/ at our website www.positive-energy.com.

Of Whole House Fans and Rebates
I've been doing a lot of research lately on whole house fans, and wanted to share some of my findings. All whole house fans do one thing - and that is to bring night time air through the house and out through the attic. This cools off the attic (that can get up to 190 in the summer) and the house as well. You close up the house in the morning to keep that night time air inside. Some things that make a whole house fan work better - multi-level homes instead of large one floor ranch houses, a tight home, willingness to open windows at night, close them during the day.
