Unclebilly,
Nova Scotia is currently trying to wean itself off of coal. A decade ago 80 % of our electricity was made that way and believe it or not, we import coal from South America for about 50% of our current requirement. Shipping across the country is not economical and what is left in the ground is either bituminous or just too costly to dig out. At one time Nova Scotia had the deepest coal mines in the British Empire. Those days are long gone, thankfully.
Also natural gas doesn't make it past PQ. We have some offshore, but not a great amount. Bringing electrons through PQ may be in the cards, but a UHV DC line was built a few years ago from Labrador to Cape Breton and was a long time getting up to speed. Wind at times gives us 50% or more, but unless they start installing turbines on the federal and provincial legislatures, wind is not something upon which one can rely. I should also mention our rivers are quite short as are our mountains, so hydro electric generation is about 10%.
We are however on the 45th parallel and last year my solar array made more power than I used. Also a new line parallel to the existing one linking us to NB will be built with a link to the nuclear plant at Point Lepreau.
I came to believe some time ago that a broad based application of resources is the best approach and anyone who tells you they have the answer to all your problems is trying to sell you something.
Best
