Do you have any idea how much energy is used in the form of combustibles to heat homes, and power vehicles? It's absolutely massive. Beyond this - the energy density of Petrol is something like 25-45x that of batteries - meaning for the same weight of fuel as a battery, you can go MUCH further, even factoring in the lower efficiency of an ICE engine (20-30%) vs. Electric (something like 90%). However, Electric Vehicles also have higher ware and tare on roads, tires, breaks, bridges, etc. And that means a higher TCO (Total cost of Operation) outside of the vehicle itself.

You might say "Improve Public Transport" And I'm all for it - but that requires doubling the average population density in urban centres to START to be practical. And achieving that is a decades long (like closer to half a century, if not longer) undertaking that has a huge environmental cost do to the tare down of existing buildings.

What all this means: To replace combustibles, we don't just need a tripling of Nuclear - we need to increase it by an order of magnitude (10x it for clarity), 2 orders of magnitude increase of wind (100x), and we should aim for three orders of magnitude for solar (1000x). If you do that, AND improve average home insulation value, then we can start to get somewhere reasonable.

To be clear: We can do it.

1. Solar Roof Incentives for generally sunny cities (ex. Calgary)
2. Off Shore Wind
3. Dual Use Installations - So Parking Lots with Solar Covers for instance. Bonus points for onsight energy storage to buffer generation for charging cars.
4. SMR's for remote area's (think far northern area's where diesel generators are the norm, as it reduces the need to ship fuel)

You will note that Hydro isn't listed here - and for good reason: The environmental destruction, and long term upkeep is extremely impactful on the environment.

All of this, by the way, is something like a trillion dollar investment. And what is the Canadian Governments investment plan? 4-5 billion by 2035? If the Canadian Government wants to get serious - they need to start making the entire government beaurocracy far more lean, far more mean, and take the savings and throw it into everything that reduces power use, as well as renewable generation.

And finally: Start jacking up the minimum wage, start increasing labor protections, and the entire why? So that people can afford to invest into these things for themselves on a wide scale.
