I think it's more frustration. Pointing out there is a maintenance cost to infrastructure is silly and doesn't add to the discussion.
We all know materials have to be shaped into machines to extract energy.
If you had a concern about the material costs of renewables you should know what they are and if you wanted to have a good faith discussion, you'd also be able to compare against legacy energy material costs.
My gut response to your post was also aggression, not because you’re preaching uncomfortable truths, but because you’re repeating fossil fuel lobbyist talking points that I’m getting really tired of seeing all over social media.
Im with you I hate the people who preach fossil fuel talking points. I also don't like the shady solar sales people who say solar is a no brainer - they are just pushing product to install on your roof. It is a pretty good product but not 100%.
Lingan Generating Station would be a typical example. Big thermal power station, built to burn local coal, realistically the transition for them is to non-coal thermal power, burning LNG or Oil, or trees or whatever else can be set on fire. If they burned trash (which isn't really a practical conversion, but it's a hypothetical) we could argue that's renewable because it's not like there won't be trash, but otherwise this is just never going to be a renewable power source.
Canada is a huge place, so I don't doubt that none those coal stations are near you (unless, I suppose, you literally live next to Lingan or a similar plant but just aren't very observant) but most of us aren't self-sufficient and so we do need to pay attention to the consequences far from us.
Ontario, Quebec, BC and Alberta, the four largest provinces by population and a heady percentage of the land area, have zero coal power generation facilities.
Ontario is mostly nuclear supported by hydro, with an absolute fallback of natural gas. Quebec is overwhelmingly hydro + wind. BC is mostly hydro. Alberta is mostly non-renewables like natural gas, but phased out its last coal plants.
If someone is in Canada, odds are extremely high that there is no coal plant anywhere in their jurisdiction. I also wouldn't say that there is a whole bunch of coal power online -- they're an extreme exception now.
Coal isn't one of the "convenient" fossil fuels where you might choose to run electrical generation off this fuel rather than figure out how to deliver electricity to a remote site, coal is bulky and annoying. Amundsen Scott (the permanent base at the South Pole, IMO definition of remote) runs on JP-8 (ie basically kerosene, jet fuel), some places use gasoline or LNG. I don't expect hold outs in terms of practicality for coal, it's just about political will.
Sure, it's embarrassing that we still have any coal plants. But really, there are only eight small units remaining, located in the provinces of Nova Scotia (4), New Brunswick (1), and Saskatchewan (3). Every other jurisdiction abolished them.
Maybe small nuclear will be the solution for these holdouts. The fact that Alberta held onto coal for so long, and never built a nuclear plant, was outrageous.
Fantastic virtue signaling. Of course totally devoid of any mention about the individuals picking raw materials for those electric car components though, since they're not "our" children.
You think elves drill oil and mine coal?
