I think we want to be careful about the line between diversification and picking winners. I'm just thinking of my experience working in this industry. What is the new green economy going to be? It has been everything from hydrogen to CCS, to wind, to solar, and that's probably over an eight-year span. So our ability to say what the energy system will look like in 30 years, and to engineer an economy for it is very challenging.
I might echo, in this case, Janet Annesley's testimony from earlier in the week, to the degree to which Alberta as a province and also the oil sands industry as a whole are driving the training in some of those disciplines. I think you've seen a really hard pullback to some of the trades which you've talked about. Stephen Gordon has written about this; a real pull-up in salaries in those trades, which has been driven right now by the oil and gas industry, but is going to have that benefit of future training and developing those skills wherever the economy leads, with or without that active push from government.
