The Off-GridGreen Myth, Part II

When Professor and Canada Research Chair Phillip Vannini came to visit us recently as part of his research on people who live “off the grid” he had just come from an off-grid home north of Toronto. This couple had indicated to him that they had gone off grid for “environmental reasons.” I can’t remember their exact distance, but let’s say they were about 50 miles north of Toronto (which you’d have to be to be able to afford any amount of property these days.) And it turns out that they worked outside of the home… in Toronto. They commuted back and forth every day.

Perhaps you can see where I’m going with this. Everything they do from an electricity energy standpoint is being offset by their transportation energy use. And what’s worse, in a province like Ontario where more than 55% of our electricity is nuclear (which I don’t like but which doesn’t emit carbon like coal) and 20% is hydro (with wind and solar gaining some ground as we close coal plants) electricity isn’t the problem for most people. It’s transportation and heating. Burning natural gas to heat your home or hot water is the problem. You take sequestered carbon and burn it and release that carbon into the atmosphere.

If you look at the Ministry of Natural Resources data for Canadians as a whole, which includes some provinces like Quebec and B.C. where most of their electricity is generated with hydro (water), and places like Alberta which is mostly coal, you see that really, electricity use in the house isn’t that big a deal. Almost 80% of your carbon footprint is how you heat your home and your hot water.

So really, in many places throughout Canada, going “off-grid” from an environmental point of view doesn’t make any sense.

In this article from a recent edition of the Toronto Star newspaper, a family decided to spend $30,000 to go off-grid rather than $42,000 to get connected to the grid.

(Note to our U.S. Readers - In Ontario, many people refer to “electricity” as “hydro” because our main utility “Ontario Hydro” started out exclusively producing power from hydro electric dams at Niagara Falls.) 

In the article the owner talks about using natural light as if it’s a big deal. And they use a “tankless” hot water system so they are not constantly heating water. That’s the way to go off-grid.’

But he’s already explained that he uses propane for his fridge, stove, hot water, back-up generator, and heat. So he really hasn’t gone off-grid, he’s just gone “on propane.” And propane is expensive. I’d think that over the long run he would have been way further ahead to go “on-grid” and use electricity for all of his thermal or heat loads. His lights are no big deal. They are a tiny fraction of his over-all household energy use. He has batteries but since he’s only there on weekends, it will be harder for him to keep an eye on them and maintain them properly. Poorly maintained batteries don’t last as long, so his savings in going off-grid will be further compromised when he has to replace his batteries earlier than usual.

This is a weekend retreat. So this family drives there, about 3 hours each way, every weekend. Their carbon footprint is massive. Which brings us to the other disturbing thing we learned from Professor Vannini about off-gridders. They love to fly!

Professor Vannini and Jonathan had both been to India and we explained that even though our daughter and future son-in-law are planning on holding part of their wedding celebrations in India (Dhruva is from India and much of his family still lives there), we won’t be going because “we don’t fly.” This is a particularly difficult decision under the circumstances but after two decades of reading about climate change we’ve come to realize that one of the worst things you can do for the planet is to fly. “If you fly you destroy other people’s lives.” (As George Monbiot explained in his book “Heat: How to Stop the Planet from Burning) Residents of the Maldives are already feeling this effect because their island nation is sinking under the rising Pacific. Their government is now trying to purchase land to move to. I will not inflict that on another member of the human race.

In fact Professor Vannini had never met someone who chooses not to fly for environmental reasons.

It turns out that this is not the case with most off-gridders, according to the professor.  He said that most of the off-gridders he had met tended to be well educated and have higher than average incomes, and they love to travel. So apparently people aren’t going off-grid to save the planet. I just found that so depressing.

I have found this paradox with many in the environmental movement. They are concerned about the fate of the planet and yet they are hell bent on seeing as much of it as they can afford before it’s gone. On one hand I get this, but on the other, I don’t understand what they think the green movement can do to save the planet if people who consider themselves “green” can’t stay in one place. And when they go off-grid they need to actually look at their carbon footprint and figure out how best to reduce it. Governments can only do so much. At a certain point it’s personal action that matters.

As I write this on March 21 the temperature outside my Canadian home should be about 5°C (40°F). But I’m in my shorts and it’s 24°C (74°F). It’s been this warm for a week and it shows no sign of cooling down anytime soon. It’s the prime season for me to be accomplishing a lot of outside work but it’s TOO HOT! On the news they mentioned that Chicago was hotter than Florida.

Sigh…  Can you buy Prozac over the counter? Hey Michelle, dig out the chocolate treat box. I need some chocolate!

The mild winter was apparently caused by an over active jet-stream. An Newfoundland (Where I am) has had the coldest winter for a few years, it was -10 C last night. I think it's -5 C now.

So many mistakes & so little time to disabuse you of them. (A)You display pretty faulty logic: that flight you're not going to take to India is going to go there anyways, with or wthout you. You'e not saving any "carbon" by staying home.(B) Whatever happened to that suit the Maldives were going to file against industrial nations over GW? And why has the govt there built a multi-million dollar resort to attract hi-end tourists if they think they're sinking? (C) It's been hot here in Chicago too, and record cold in Europe. Rome had 3 deep snowfalls this yr. It usually gets a light snow once every 30 yrs. Also- largest snow storm ever in Pacific NW. It all averages out. (D) Add up all the people killed by nuclear generation of electricity in the past 60 yrs and then explain why you don't like nuclear. (E) The dopes that spent $30,000 to stay off grid instead of $42,000 to go on grid will have to repeat the expense every 20 yrs or so. Forever. (F) You're right about many of the short sighted efforts of TreeHuggers to be "Green." They do it to satisfy their consciences, fantasizing that it actually solves problems.
