so build some solar and wind much more south? Alabama AND Arizona for example. electricity is the cheapest form of energy to transport
Mighta missed it, but between Ontario and say Arizona there's at least 1800 miles. And between Ontario and Alabama it's around 1k miles. While the NA grid is somewhat interconnected, there are still separate network grids in case of catastrophic failure. On top of that, there isn't a big nationwide high voltage DC grid for the delivery of power from plants. And HVDC is the only way you're going to be transporting power that far while reducing the loss. AC it actually becomes very cost prohibitive very quickly over very long distances and more electricity is lost due to resistance and heat.
Ontario's best solution for electricity has always been nuclear, followed by hydro-electric to round it out. Followed by coal and natural gas for peak demands. The current government(Liberal) decided that "coal is nasty, evil and dirty" and shut them down, instead of say retrofitting them. And there were even a few leaked documents that they wanted to do the same with natural gas power plants and wanted to ban natural gas for home use, forcing everyone onto electric. The price started climbing quickly once these cheap sources were removed from the grid.
If you want to see this insanity in action, go look at the current NDP government in Alberta. Where they're pushing the same policy. The problem in Alberta is, whole lotta area and people are very spread out. Coal is plentiful, and in turn small out of the nowhere places where it's cost prohibitive to build NG, impossible to build nuclear, and where solar or wind is also prohibitive. They're now scrambling to build thousands of KM of power lines. Small towns and cities like Grande Prairie and Grande Cache rely on small scale coal plants to keep people from freezing to death in the winter when there are grid failures for example. The winter I spent in Grande Cache, the nighttime lows hit -48C with a windchill of -55C. The daytime highs were between -25C and -38C not counting windchills. We had 3 days with no power due to high winds, the mall, fire dept, and all government buildings had power though. So people who didn't have wood as a backup, could safely stay somewhere.
