Money is a moot point because either way you’re investing in something, either CC or EC. As far as time goes, when it comes to climate change I don’t think time is on our side either, so we don’t have time to wait to develop actually effective CC. We need to be making a transition to renewables now, and smooth out the jagged edges along the way, we don’t have time to wait and hope for a magic technology to eventually make our fossil fuels less dirty
The efficiency of CC is higher when you’re doing what you’re saying and capturing at the source but it’s still incredibly inefficient and the costs are just astronomical to get it anywhere near a level that would actually make a dent in the emissions. With the current costs today, it would actually be cheaper to tear down a coal power plant and build TWO wind farms that supplied the same amount of energy each than it would be to build CC to capture a fraction of the emissions generated by the coal plant.
And before anyone says that the costs of CC will come down in the future… So will wind farm costs and solar costs, so in the end why build something to reduce emissions when you could build something to completely eliminate them for CHEAPER instead?
Middle density housing is severely lacking in most of Canada. Montréal is one of the few cities that does have a bit of mid-density housing and its housing costs are lower than most other similar sized cities. Obviously there’s many more factors but I definitely think mid density is important for reducing this crisis.
