Another impediment to green energy transition in Canada is that our regulated large-scale conventional power generators have reacted to the threat of DIY solar hollowing out their customer base by dramatically altering their billing practices and not in a helpful way. The typical electrical utility bill in Canada these days is increasingly comprised of regulator-approved fixed charges that are by definition not sensitive to electricity usage. So, if you hang on to your conventional utility service for either energy diversification purposes or any intent to sell your surplus solar back to the utility, you now face significant monthly fixed charges simply for the right to remain connected to the grid.
As I understand it, the traditional practice of electric utilities was just to figure a global mark-up to apply to all electricity sold in order to cover the cost of maintaining connections. This obviously breaks down when some customers go solar.
A lot of these sorts of issues could probably be addressed fairly effectively by pairing something like a demogrant with whatever policies you want to promote/discourage. It's generally good, for example, for people to go solar, but probably the ability to do that is skewed toward the well-to-do, regardless of how you structure incentives; just owning your home rather than renting is one confounding matter. Monopolistic and near-monopolistic utilities are already quasi-government -- why not just cover the cost of maintaining lines from general revenues?
But in America, at least, I don't recall ever seeing such a thing seriously proposed.
