Ontario Government Giving Every Household a Say in Province’s Electricity Future

The Energy Minister wants your thoughts on the Supply Mix. Quick, do you know what the supply mix is? Do you care?

I’m guessing that, as long as the lights are still on, that you can read my blog, the fuel bills aren’t too high, and acide rain hasn’t caused the cat to rust, you don’t really care about the Supply Mix.

But Donna Cansfield wants you to care. She’s sending everyone a brochure Our Energy, Our Future (online here) to make you think that they’d give a one before they go build nukes anyway. And since you were consulted, it’s your fault when the cost overruns roll in.

“The clean air choice of Earth Day Canada.”

So, what would you think would be “The clean air choice of Earth Day Canada“? A bicycle, perhaps? Some kind of renewable energy? Some really brilliant Canadian enviro-social development, like a biodegradeable donut?

Nope, a car; the Toyota Prius. Last time I checked, it still used petroleum (with its high environmental and geopolitical toxicity). It still causes gridlock; I see Priuses (Prii? Your moon-pie eye!) inching along the Gardiner from the GO train with all the other wretched junkers. The way I see it, it’s not looking like part of the solution. It’s a bit like having an official assault rifle for the the International Day of Peace.

Toyota also give out $5000 Toyota Earth Day Scholarships. I mean, that’s nice and all, but it’s hardly giving back. If you look at all the scholarship materials, it’s carefully arranged so it looks like the event is called Toyota Earth Day, with the ‘scholarship’ on the next line. Nice cooption. Good greenwash.

canwea over

Well, that’s CanWEA 2005 fully over. Yes, I’m still sifting through the contacts, brochures and swag I picked up, but it’s back to work for me.

I met a lot of people (including, quite unexpectedly, Stuart Hall of Natural Power in Scotland, whom I hadn’t seen in about 8 years), and the show seemed to be absolutely jumping. Could 2005/2006 be the year that Canada gets wind energy?

Debunking the 25% Myth

My dad called yesterday, asking, “Wind turbines do run for more than 25% of the time, don’t they?”. Seems he read an opinion piece in his favourite fair ‘n’ balanced rag (The Telegraph) that said that wind turbines only run 25% of the time.

I see this factoid popping up more and more from the anti-wind crowd. It’s a particularly difficult one to refute in the press, as by the time you’ve tried to explain the difference between capacity factor and operation time, you’ve lost them. Or gone over your allotted time/word count, at least.

I’ve got a year’s production data from WindShare/Toronto Hydro‘s turbine in front of me. It’s on a marginal site, one that probably wouldn’t be developed by a commercial entity. So, does it run for more than 25% of the time?

Yes; the turbine is generating 63% of the time. I’ve defined generating as providing a net export of power to the grid. Our turbine’s a bit more cranky than most, and I have a suspicion that our metering system is dropping some production, but even so, 63% is way more than the claimed 25%. So it gives me great pleasure to say:

MYTH: Wind turbines only run for 25% of the time.
BUSTED! Wind turbines run at the very least 60% of the time, usually more.

(I can’t guarantee that Country Guardian won’t quote me out of context. I could make a cheap shot about not blaming them for their paymasters in the nuclear industry requiring value for money, but I won’t …)

my wind-powered PC

As a thank-you for speaking at the ESC/EWB Power Shift lecture series, I was given a Pembina Institute Wind Powered PC tag. That means that the energy equivalent of three years of PC usage has been bought for me from a windfarm.

I’d like to thank the folks at UofT for putting up with me for the evening, and buying me dinner at the (in)famous Peel Pub (would that be innfamous?). I enjoyed it, and I hope they did too.

Sustainable Energy Fair

I survived the University of Toronto First Sustainable Energy Fair. The weather was pretty grim, despite the cold and the rain. Maybe some of the solar cooking events didn’t happen, but that didn’t dampen the spirits of all involved.

There was a good crowd, and I talked myself hoarse on the WindShare stand. There were some interesting people there, including the irrepressible Tom Karmo, and UofT‘s own cyborg, Steve Mann. And yes, I am really responsible for getting Winton Dahlström into wind energy; mea maxima culpa.

I have pictures of the sustainable energy fair here.

Sustainable Energy Fair at University of Toronto on April 1st!

I will be there, on a rather small WindShare stand. Here’s the full blurb:

Where you can you eat a free veggie burger, meet the student,
academic and industrial leaders of the sustainable energy
revolution, and win cool prizes for guessing your environmental
footprint?

Only at U of T’s First Annual Sustainable Energy Fair, which is
happening on April 1st, from 10am to 4pm, just south of front
campus at the intersection of King’s College Circle and King’s
College Road!

Companies representing every major sustainable energy related
industry – wind, solar, geothermal, biofuel, and hydrogen – as well
as representatives of community power co-ops, will have booths at
the fair. U of T research projects related to sustainable energy
will be on display, and student groups concerned with these issues
such as Engineers without Borders, the Energy Sustainability
Community, Science for Peace, the Blue Sky Solar Racing Team, and
the Hydrogen Fueling Station Design Team will host exhibits.

In addition to this, there will be free food cooked on a solar
powered barbeque, informative contests, construction activities
(building mini-turbines and assembling a hydrogen fuel cell model
car), and prizes (CFL bulbs, low, flow showerheads, fair trade
coffee and chocolate).

Come on out, join the fun and learn more about the future of
energy!

What Every Householder Should Know

do not use on aluminum warning from washing soda package

According to the CBC, a Canadian has patented a method for extracting hydrogen from aluminium. While this patent has some extra specifics to deal with managing the reaction, it’s not that far removed from the old home science trick of dissolving aluminium foil in washing soda. Indeed, every box of washing soda I’ve used has come with the warning message above.

It takes a lot of energy to form aluminium from its various ores. According to an Alcan report, it takes over 15.5 kWh/kg to do this — that’s over 55 MJ of power per kg of metal. Smelting aluminium can also be massively polluting. I’ve heard tell that the smelting plant near Fort William used to turn the surrounding hillsides yellow from the fluorine emssions.

I haven’t done the sums properly on how much hydrogen a kilogram of aluminium will produce when reacted with caustic soda, but it’s probably going to be less energy than it took to form the metal. You’d also have to deal with disposal of alumina sludge at the end of the reaction, which is mostly harmless but bulky. There’s also a huge amount of heat evolved by the exothermic reaction, and thereby not turned into useful chemical energy. It’s a similar reaction those caustic soda/magnesium metal chip drain cleaning powders, and you know how hot they make the drainpipes.

This patent seems typical of many of the methods that are being thought up in our mad dash to a hydrogen economy; uneconomic, inefficient and ill-advised. But you can’t criticize it publically, ‘cos everything going to be running on hydrogen soon, isn’t it?
