Try to dismantle a nuclear plant. It costs tons of money and time. Ask the people at Nagasaki or Tschernobyl.
Dismantle a coal power plant takes time, but one can reuse the iron and such. All the open mining fields and mining tunnels are the problem. In Western Germany, there are areas where house crack or cars fall down sudden openings caused by old mining tunnels.
Try to dismantle at wind mill or solar fields. It’s a quest of days and some bucks.
I prefer the easy way of living. So, my favorite are renewables.
You dismantled your plants because dismantling your plants is hard? 🤔 That seems backwards. Why not upgrade? Then you never have to dismantle. Keep it alive forever.
Upgrading would have cost way more. one of the reasons atom power is so expensive (without government subsidies) is the cost of the plants which needs to be recouped as well as the price of the uranium. not to mention that we haven’t found a suitable place to store the waste for those thousands of years until it’s harmless.
Who cares about cost. We should be willing to pay whatever it takes to end fossil fuel use.
