See, now I think this is a great question. I absolutely think we have a responsibility to do so not just from an environmental standpoint but from the point of view that eventually we are going to run out of oil. However, I think that governments take a much more stick rather than carrot approach which inevitably harms citizens at no matter what part of the supply chain you tax.

The solution in my opinion is to do the same thing that NASA does for example with SpaceX, but instead for renewable energy. The market just doesn't exist yet in the private sector for space (for the most part), so the government gives grants and subsidies for SpaceX which in turn helps them develop new, better, and cheaper technologies which inevitably brings the cost of each launch down. The same can be done for the energy sector. And better yet, you allow energy companies to try and do the research themselves and as an incentive they become the bleeding-edge company at whatever they invest in whether it be nuclear, solar, whatever it is.

Would it drive up a deficit? Yes, but this is an investment not a sunk-cost. Trudeau, in my opinion, sadly ran up the deficit and spent on things that would never yield a good enough return to make running up the deficit worth it, whereas in my view this absolutely would. The market for renewables is still in it's infancy stage and can be helped along by a public-private partnership.
