How we use coal and how they use it are entirely different. Sure they toss it in and burn it just the same but the emissions from a coal plant are significantly cleaner. If you’ve never been in a modern coal plant you really don’t know how they work.
…Then again you also don’t know just how much coal they use. It’s an insanely, ridiculously high amount. Like you see how many tons they use and you’re like “so that much per week or month” and they reply “oh no no that much per day”. This is why nuclear plants need to be cheap and easy for companies to build and take about 20 years less to get approvals for.
Fun Fact: Coal plants have a 20% variation on power output based on outside temperature. On cold days 10% less than rated, on hot days 10% more.
