Should I get rid of coal power?

[KesslerK09]

Let me explain my situation. I modded Bulgaria, Romania, and Moldova into one country. I'm currently in 1965 and my economy is doing well. I'm producing a lot of electricity and I'm making some good money off of it. In the 50's I invested heavily in coal and a lot of hydro power. Now it's mid 60's and I've build up a decent amount of nuclear power and I want to keep building more. Though the profit is nice I want to start ridding my country of coal power in efforts to bring down facility/production costs. I just want to know if this is a good idea or should I keep my coal plants?

IMHO coal power is the cheapest. And since there are no any enviromental effects or pollution, it is the best thing too keep them...

I stuck with them and it paid off. I left my game running and came back and I needed to quickly expand my industry and consumer goods. If I destroyed those plants I would have been screwed... But as soon as I can Adv Other/Solar I'm switching them out.
