New Year’s Resolution: Reducing my carbon footprint

Making my Resolution was pretty easy, figuring out how to implement and assess it, not so much.

I’ve been doing a bit of reading over the holidays, Bernstein’s Aquaponic Gardening, Coleman’s The Winter Harvest Handbook: Year Round Vegetable Production Using Deep Organic Techniques and Unheated Greenhouses and some of the blogsphere including Roberts’ Brutal Logic posts here  and here as well as some discussion about the “marketing” of climate change with scare tactics like Roberts vs. a gentler approach to reach the electorate, see two sides here and here.  I’ve also glanced into some alternate perspectives including Worstall at Forbes arguing that delay in addressing climate change can save money (I think his logic is faulty). Also supporting the go-slow path a friend recently wrote me “But considering that 50% of American’s make less then $26,000 a year [what with] buying food and paying rent…well there isn’t money for those high end [climate saving] purchases. You can’t squeeze blood out of a turnip.”

I’ve got my monthly utility bills from Avista for gas and electricity in 2010 and 2011 which gives me some baseline. Avista’s electricity comes from a mix of fuels, including coal, gas and nuclear. They give information that should let me adjust my KWH to the fraction that is carbon-based. I don’t have records of gallons of gasoline purchased. My house is heated with wood, which raises some different issues about pollution and I have no handle on the amount of wood I use or its carbon content. And then there is the issue of adjusting my use of heating energy to account for the weather in the 2011 and 2012 heating seasons. Avista gives degree days in its bills but with a wood stove, there are days when you just don’t heat because you are not around to stoke the stove.

So, I am going to make my Resolution more specific:

Regarding gasoline – I will track how many miles I drive and how much gas I use and return to this challenge in 2013.  I put log books in each vehicle to begin tracking miles and gallons purchased. I can use these logs to also record gas purchases for lawnmower, chain saw and the like.

I previously challenged myself to buy only one tank of gas a month, but that challenge is complicated by having multiple vehicles and by using the in-laws’ vehicles at times. To give me something I can assess for 2012, I will aim to buy no more that 150 gallons of gas for the white car and blue truck I drive and for my various gas powered tools. Bicycling around Moscow has shaved my waistline, this is a path to continue.

Regarding electricity and natural gas – Last January I was thinking about these issues in terms of “buy local” and how to shift my purchases from Avista to spending locally. I have experimented enough with a clothesline in the greenhouse that I can see some reduction in electricity use. I need to build on this effort to reduce our footprint with Avista.

Sharon Cousins has advocated solar ovens enough to get me to try one and to build one, but I’ve not lived with them enough to make any claims that I am substituting solar energy for Avista energy. This is a path to continue. I’ve played with a mud oven and retained heat cooking, again not enough to make any claims about substituting wood as my baking fuel. Recently I found a hybrid idea, retained heat solar oven. Something to explore designing into the shared use commercial kitchen I am building.

In the Peterson Barn Guesthouse, my next steps are probably to use solar to supplement space heating and in our house, I’m working on pre-heating our hot water with solar. Both projects are low budget, a fan and ducting to blow excess warm air from the greenhouse and a homebrew rooftop solar collector.
