I have done the analysis for Ontario. I can say that to get to the 2030 targets, we must consider the electrification of transport, which includes the trucking system, the rail systems, electric vehicles, hydrogen-powered options, and all sorts of stuff like that; as well as winter heating. Between all of that, Ontario is going to need 60% more electricity than it currently has. To get to 2050 you can double that again, so it's a lot.
That equates to 14 new nuclear plants in the next 15 years if you want to meet 2030 targets. That's how much electricity is needed. It's a lot.
