> As much as I'm against fossil fuels, coal powered plants only contribute a very minor part to global warming compared to lets say... ships, planes and cars.

Do you have a source behind this? From what I can tell this statement seems wrong. E.g.:

https://www.epa.gov/ghgemissions/global-greenhouse-gas-emiss...

https://ourworldindata.org/energy-production-and-changing-en...

Coal is a huge source of energy. And the dirtiest available. And if electricity+heat production accounts for 25% of global greenhouse gasses, and transportation 14%, there's a decent chance coal power plants contribute just as much to global warming as all of transportation does, and basically zero chance that it plays a "very minor part" when compared to ships, planes, and cars.
