23 Mar 2010 Sustainable Dishwashing: No More Plastic

Have you scrubbed a pot using one of those green scratch pads lately? Most of us have. Did you know that they are made of oil-based plastic that breaks down as you scrub and those small pieces go down your drain, into the municipal water treatment, are filtered out and end up eventually in the Bay and ociean? Along with microscopic broken bits of plastic bags and bottlecaps they become part of fish and crustacean diets. Plastic has now become a defacto part of seafood flesh - yum, yum.

Solution? Loofah & agave scrubbers. Loofah (my sister grew some in LA one year) & agave are plants. Loofah can be purchased as a yarn if you have time to knit or crochet your own scrubber. 3M, just started making scrubbers from agave (found some at Target) but there are probably others (let me know in comments).The sponge part of the old double-sided scrubbers been natural sponge but with chemical dyes (bye-bye purple, orange, blue). The new sponges are made of recycled paper and natural fibers and have no chemical dyes.

I’m less enthusiast about the 3M soap loaded scrubbers. Soap is phosphorus free and scrubbers are from recycled plastic, but, again, plastic bits into the water stream. Their wipes are from bamboo, rayon (pulpy part of cotton plant), cotton & corn, presumably new material since recycled isn’t mentioned but all are compostable. Read labels & go online for details.

Remember, you don’t need to see scads of bubbles for a dish detergent to do its job. Though it seems counterintuitive, rinsing with cold water is best because bacteria thrive in warm (i.e. temperatures that our hands can handle) water but not cold.

Absorb grease and other food stuck to plate with old napkins, paper towels and put in garbage. Keep a strainer in the sinkhole. The more grease and food particles that go through your municipal water plant, the more energy they must use to clean your water.

05 Mar 2010 Old Refrigerators & Freezers are Top Energy $ Wasters

1997 was the year that Amana won a department of energy prize for developing a refrigerator technology that cut energy usage 50%. Sadly, I bought my new top-of-the line model in 1996. You can learn from my mistake, though. Because they are on 24/7, refrigerators and freezers are a household’s top energy user. If you have a pre-2000 model, take a close look at your paperwork for it’ EnergyStar rating.

Here’s an Refrigerator Retirement Savings Calculator to help you determine if your annual savings might quickly repay the cost of a new refrigerator.

PG&E & other utilities are starting to offer rebates for old fridges, as well.

Consolidating so you can eliminate an extra fridge or freezer is a good first step. Keeping both your fridge & freezer compartments full, even if just with water jugs keeps them operating more efficiently, is another.

Wako has many more details on her Everyday Sustainable blog, so I won’t repeat.

24 Jun 2009 Going Solar: How going off-grid can and can’t help

We installed solar electric in July 2007 in Northern California and up to now have been using the excess energy we produced in the summer. When you install solar in PG&E territory you change from a residential customer to a commercial producer and receive a monthly acccounting. As days become shorter and colder we use more electricity and we’re starting to eat into our surplus. Next July will tell if we properly projected our usage and size of our system. Marin Solar did our installation and we are extraordinarily pleased with their service and work. We used Sunpower panels which, at the time, were the most efficient panels available.

Being an accountant, a cost-benefit analysis was a must. Being house rich and cash poor we took out a HELOC loan to pay for the system but our monthly payments are equal to our previous average electric bill. The past 3 years electric bills increased an average of 12% yearly so just keeping the monthly payment the same will save us from energy cost inflation.

I’ve been considering a solar battery charger to keep those pesky batteries on cell phones, iPods & cameras on ready call. Some research though is making me reconsider. The jury is still out on this decision.

Update, July 2008: PG&E, calculated our year-end descrepancy and we owed the equivalent of one month’s bill to them at year end. This was mainly because much of the family decided that “since we have solar, it doesn’t matter how much electricity we use” - NOT!

We’re looking into solar thermal (hot water).  I understand it, there is great variation on recommended systems depending on what part of the country that you live in so read this \”Homeowners Perspective\”, based in the San Francisco Bay area, with that in mind. Search out solar hot water information based in your local area for the best info for you.

24 Jan 2009 Towards Sustainable Auto Transportation

Amory Lovins in the 8/26/2007 issue of Newsweek spoke about steps the government can take to slow oil addiction.

He also made is short, sweet and to the point on how the average consumer can promote energy efficiency in personal auto transportation:

1) Get the most energy efficient vehicle (both in terms of energy used to manufacture the car and energy it uses). Drive the vehicle properly to maximize efficiency.

2) Be thoughtful about whether the trip is necessary and how many people are in the car

3) Try to live nearer to where you work, shop, attend school and recreate.

4) Push for fairer competition between all ways to get around. Write or call your legislators at all levels, attend local meetings.

11 Dec 2008 Resolve to be less “Consumed” in 2009
The holidays bring out the consumer in us even as we try to scale back. In addition to the waste we personally produce, there is a tremendous taxation of our earth in the farming, mining, manufacturing, transportation and sale of most every item we purchase and use.           

Despite my rantings about sustainability, I’ve discovered I have a long, long way to go even though I’ve made much progress. One of the best websites to find a good overall look at your personal & family sustainability footprint is Consumer Consequences . After you input your information you have the ability to compare yourself with others in different categories: house, energy, transportation, food, etc. It helped me identify which areas I should make more efforts in the coming year.

I’ve been reading online the NPR special report “Consumed” that was broadcast November 2007 and highly recommend checking it out:

Its goal is to answer the question, “Is the consumer economy sustainable?” in a serious way. They tackle the question in a comprehensive manner, with a lot of breadth but, if you don’t want to be overwhelmed, just choose one or two that most interest you.

A partial list of the featured topics: ecological footprint, landfills and the waste disposal sector, consumer debt, air pollution, freegans, marketing, junk mail, energy independence, the effect of consumer culture on mental and emotional well-being, carbon tax, food miles, fashion obsolescence, the green economy, e-waste, clean tech, globalization, Bhutan’s happiness index.

Interesting things to ponder as we consider resolutions for 2009.
