The grass is greener over here!

Yard full of unmowed grass

Reduce your carbon footprint, grow your grass!

The grass is always greener on the other side, or maybe it’s greener on my side. I recently thought of a way to reduce my carbon footprint and get extra seed for my lawn … naturally. It was a eureka moment. Let the grass grow long enough to produce seed. It not only gets well established but it chokes out weeds. I didn’t expect that. I suppose it also allows for creatures to move freely and encourages my yard nemesis, poison ivy, but overall it was worth it. With the money and gas saved from mowing, I believe I have reduced my carbon footprint a tad. Ya, ok, it’s time I fess up, this wasn’t a planned event at all. I simply wasn’t able to mow for two weeks because of rainy weather, then we had to wait a few more weeks because the landscaper’s schedule was backed up. But hey, the lawn looked really great, so maybe I’ll do it again in the future. Give it a try!

New Solar Array at Carlson Orchards

Carlson Orchard Ribbon Cutting August 2010

Frank Carlson cuts the ribbon for the Carlson Orchard Solar Array

This year’s harvest has been a bountiful one.  At Carlson Orchards, they’ve sown a 220 KV solar array and will reap the savings throughout the next 20 years.  In August, I was privileged to attend the ribbon cutting and witness the accomplishments of the 7 month project.  The array will account for about 60% of their electrical needs, if estimates are correct.  Carlson Orchards is located in the scenic Massachusetts town of Harvard.  Frank Carlson and his staff run a local farm business with all the challenges and victories that go along with it.  This array should prove to be a victory for them and the environment.  They put their own time and money into it, but thanks to the hard work of the project manager, Symantha Gates, they received grants from the Massachusetts Department of Agricultural Resources, Natural Resources Conservation Service, and Massachusetts Clean Energy Center.  These investments will turn the sun’s energy into a way to keep our local peaches, apples, and other perishable products available to us throughout the winter;  something we all take for granted due to shipping from warmer climes.  It’s going to be a win-win situation with the orchard’s lower electrical grid draw and lower power bills to keep the farm in the black.

Being a scientist at heart, I was very interested to hear the details of the solar array.  Here is a video I created of the lead engineer, Newell Thomas from Lighthouse Electrical
discussing the process.

Video Short – Case of the Humans

I liked the perspective of this video short…Earth is infested with humans.  It’s good to step outside our typical point of view that we are the center of the universe.  Maybe we are just parasites.

Story of a Residential Energy Audit

Energy Audit Blower

Building Alternatives performs residential energy audits

Back in May of this year, we had an energy audit done on the house.  I was very excited to have this done for two reasons.  One, because I hoped we would identify a flaw that if fixed would save us money and I had hoped we could qualify for energy rebate to curb the cost.  Second, because I love the science and tech of it.  However, I should have known that it wouldn’t be all fireworks and streamers when I entered our electric and propane usage into the energy calculators and it determined us to be “in the green”.  The truth is, our house is fairly tight-sealed.  We had good windows (double paned argon gas)…possibly the sills could be sealed with spray foam.  Also, we have air leaks in expected places for a log home (the corners).  The main place where we had room for improvement was the “attic” but it would be too costly to be worth it.  Now I put “attic” in quotes because we don’t have one.  We have metal roof, fiberglass insulation, and v-grove pine board paneling. There is room for improvement there because we could have more efficient foam board or blown insulation.

See how the audit was done in these videos:

Overall, I’m glad we did this because I got to see the process, but my advice is, if the energy calculator shows you in the green, leave it be.  Naturally, we still want to replace our traditional water heater with a tankless water heater.  Surely, we’d love to install solar panels and perhaps a wind turbine.  But these things will not be to save money in any less than 20 years.  These things will be simply because we don’t want to waste energy, especially free energy.  It’s my dream to be off the grid!

MoS Tests Small Wind Turbines

Museum of Science Wind Turbine 2010

One of the Museum of Science's Wind Turbines 2010

The Museum of Science (MoS) in Cambridge, MA is hoping to capture the wind in their new turbines and share that data with you.  In May, I went to a presentation where they explained the various turbines installed as part of the MoS study and shared their experiences to-date.

These are not the large wind turbines in farms you may have seen, like Cape Wind.

Definition from Wikipedia:

Small wind turbines are wind turbines which have lower energy output than large commercial wind turbines, such as those found in wind farms. These turbines may be as small as a fifty watt generator for boat, caravan, or miniature refrigeration unit. Small units often have direct drive generators, direct current output, aeroelastic blades, lifetime bearings and use a vane to point into the wind. Larger, more costly turbines generally have geared power trains, alternating current output, flaps and are actively pointed into the wind. Direct drive generators and aeroelastic blades for large wind turbines are being researched.

MoS is studying five small wind turbines from different manufacturers and using different designs.

Windspire
Skystream 3.7
Swift
Aerovironment AVX1000
Proven WT6000

These turbines are designed to capture low wind speeds (although they are able to withstand much higher such as 60 mph).  My key learning was that placement on a flat roof is very important and paying for a designer to map the optimal placement can make a significant difference in the efficiency.  Also, you don’t need sustained winds to get value out of these turbines.  However, the cost of the turbines may not be recouped quickly enough (which I define by < 20 years)  if you are in a low wind area, making this tough for residential installations, and possibly, in commercial installations.  MoS pointed out that ground-mounted small wind turbines make more sense in windy areas.  Personally, I was hoping to see more wind turbines as I looked out at the skyline of Boston, Massachusetts.  MoS is really paving the way.

Last Thoughts: While I was listening to the presentation, I couldn’t help but wonder if wind would be a good supplement for power where solar installations are in use.  I would postulate that there are stronger, sustained winds in the cooler months here in New England, although I have no data at this time to support this theory.  In summary, I’m not compelled to choose a small wind turbine over solar panels in either a commercial or residential installation.  The data from MoS will be available to installers and consumers, and I encourage you to check their site for more information.

Any thoughts on the value of wind over solar?  Or perhaps comments on solar plus wind installations?

Popular Excuses Not to Conserve

Excuses for not recylcingDo you hear these excuses from your family?  Do you make excuses sometimes?  It’s not always easy to conserve, in fact, I’ve been known to say or think a few of these myself (I won’t give away which ones).  In general, it’s helpful to be honest about why you don’t conserve because maybe there are ways to make it easier and remove that barrier.   Maybe there is just one of these that if changed could save you a substantial amount of money and make you feel more conservative.

It’s too time consuming
They don’t recycle these 100% anyway
It clutters up the house
America’s economy relies on energy investments
I’m too tired to get up and turn off the light
I’m running late for work and don’t have time to turn down the thermostat
No one else in house conserves, so why do I bother
The grass isn’t as green with organic fertilizer
Green products cost more
Vinegar stinks
Disposable water bottles are more convenient
Who’s gonna notice if I don’t recycle this time
There is no curbside recycling
I missed the hazardous waste disposal day
I missed the electronic pickup day
Why do I have to pay for electronics disposal?

Just as an example, here’s how you can remove a few of these barriers. Take “I like using disposable water bottles”; you could start by reducing your water bottle usage by half by just refilling each water bottle once. Also, you could find a few non-disposable water bottles that have the features of disposable bottles you like, fill them from a filtered tap, and have the ready to go in the refrigerator. Convenience is key!

X10 remote control lightsHow about the excuse “I’m too tired to get up and turn off the light”? We use X10 remotes to turn off many lights throughout the house. You can also use motion activated lights in places where it won’t annoy you, like the bathroom, the laundry room, the cellar and once you get used to those, perhaps incorporate them in the heavily used areas like the living room, the hall, etc.

Got any other original excuses or ways to remove barriers?  I’m sure you’ve got more!  Send ‘em on in via comments or email…

How Efficient is YOUR House?

I sought to see how efficient MY house was and contacted Building Alternatives to do an energy audit. They pointed me to the NHSaves website to see if I qualified for a free energy audit.  All you have to do is enter the quantity of heating fuel that your home uses in one year.  Somehow I misplaced a few of my propane bills, but one quick call got the number in no time.  The bad news is I did not qualify for the free energy audit, but the good news is our house is pretty efficient.  Since it’s not perfect, I’m still going to pay for the audit, plus it will be cool to see the audit in action.  Building Alternatives is well versed in alternative energy solutions, so I’m looking forward to hear what ideas they have and then share them with you in a future post.  Have you had an energy audit done?  What were the pros and cons?

Here’s some links to energy audit calculators:

Collaborating at MIT Sustainability Summit 2010

Breakout session at MIT Sustainability Summit 2010

Breakout Sessions at MIT Sustainability Summit 2010

On Friday, April 23rd, 2010, I had the pleasure of attending the MIT Sustainability Summit 2010.  The morning keynote was of particular interest to me since it was given by Peter Senge and I am big fan of his book The Fifth Discipline.  The subsequent keynotes and sessions did not disappoint.  They widened my knowledge of sustainability and upheld the summit’s theme of “Communicate and Collaborate for a Sustainable World”.  Here are some highlights…

Peter Senge

Peter Senge

The morning keynote was very interesting.  Having been long-time admirer of Peter Senge’s work, I couldn’t fathom how systems thinking applied to sustainability specifically.  I realize that systems thinking can be used on any process or goal, but exactly how, I wasn’t sure.    Mr. Senge used his work at Starbucks to explain that in order to make headway on sustainability, we have to collaborate.  Companies need to work at all levels of the process, from suppliers, recyclers, and basic infrastructure to achieve their sustainability missions.  The interesting part of that was how many ways there are to achieve the mission…for example, Starbucks decided not to go with biodegradable cups because the carbon footprint of the suppliers was a consideration.  Plus some of the municipalities can’t compost the cups.  I’m sure there are more than a few situations where you have to pick between two sustainability criterion that are in direct conflict with one another.  Overall, I gleaned from the keynote that good, green companies are doing the research on what method of conservation would work for them based on their regulators, suppliers, and consumers.  If these entities collaborate rather than grandstand on principles, realistic sustainability goals will be achieved in a systems thinking manner.

I followed this session up with the “Systems Thinking 101, How to See Sustainability Issues using Systems Thinking”.  I’m not sure that I got any new concepts out of this session, but it did reinforce concepts such as stocks, flows, reinforcing feedback, and balancing feedback.   This can apply to sustainability in addition to manufacturing processes, population control, marketing strategies, etc.  I agree with one of the last statements of the presentation that “simple structures can explain models” (John Lyneis, MIT).  For me this resonates because sustainability often gets clouded in difficult to present science detail.  I think for maximum adoption we really need to bring it down to earth in relatively simple terms which is different than dumbing it down.  Dumbing it down implies that people can’t understand but the truth is they want the executive summary…they want to know how it applies to them and what is the benefit to them.  Don’t you agree?

The second Keynote speaker, Mr. Kook-Hyun Moon, intrigued me with his perspective from a large corporation.  The dollars and sense of investing in your employees and the environment was encouraging to hear.  I often worry that we make enemies of corporations by over-regulation and sharp criticism of their practices without constructive feedback.  Mr. Moon explained his experience with influencing a large corporation to see the value in sustainability and elevating the workers and the neighboring people.

Another breakout session I attended was on Fair Trade.  At first glance this didn’t seem like a deep subject.  It’s pretty simple right, buy Fair Trade products if you support the environment.  There is more to it than that.  Namely, who are the members of Fair Trade coops?  And what value does certification have for Fair Trade products?  I would say, it has a high value based on the level of debate we generated talking about whether to allow large plantations to be certified or not.  It would be hard to boil down this discussion in a few sentences, but suffice to say that in emerging countries, large plantations can influence government and have huge advantages over the coops.  This doesn’t necessarily make them bad, but can they be a part of Fair Trade?  This is an interesting topic that I hadn’t considered.  Check out Equal Exchange for one example of Fair Trade Coop.

End of the day at MIT Sustainability Summit 2010

End of the day at MIT Sustainability Summit 2010

My last breakout session of the day was Green Marketing.  Here I found a lively panel discussing techniques and challenges for marketing to those who value sustainability.  They don’t feel that green marketing is really different than regular marketing, instead, they posed that the same concepts are upheld.  Concepts like being authentic and strategic.  Just slapping a green label on a product doesn’t make it so.  Consumers want to know why it’s green and want details about how it is environmentally friendly.  They also widened my thinking by explaining that any product can be “greener” than it’s competitors and that gives it an advantage even if the product isn’t particularly green.  Diana Verde Nieto used Avis as an example.  By providing environmentally friendly cars for rent and stating the fuel saved on average trips, they became “greener”.  Trust from the consumer is hard to get.  During a quick poll of the room, the panelists asked which organizations we trust to point us to sustainable products.  Very few people piped up and those that did said they trusted Consumer Reports and Good Housekeeping but not much else.

This was a great summit and I’m glad I was able to attend because it challenged some of the ways I think about sustainability.  I hope to collaborate with my neighbors and support my local businesses in sustainability efforts.   We can all influence someone to save a little money and save the planet.  What suggestions do you have for collaborating on sustainability?

Town Spring Cleaning

It’s that time of year again when we pull back the curtains to let the sun’s rays stream in only to notice the tiny particles glistening and falling on our seemingly clean surfaces.  Suddenly, our awareness to just how dusty everything is comes to light.  It’s the same outside, the snow has receded (or in our case, the floods) and so much litter and natural debris is left behind. Yes, it’s time for Town Clean Up Day!
