The problem with coal is not mining it. The problem with gas and oil is not drilling for it.
These things have a minimal impact on the local area where they occur - but not a good one, granted.
The problem with coal, gas, and oil is BURING them.
Because if produces large, global amounts of carbon dioxide. A “green house gas” that causes the earth to retain more of the suns heat rather than reflecting it back into space.
The elements you mention above are metals - they are not buried into the atmosphere. Metals are relatively easy to recycle.
If it makes you feel better, fusion reactor designs (there are a few) are starting to pan out. Lots to read about improvements beyond the Tokamak design.
And you really need to be able to handle fusion, if you hope to master Star Trek type reactors….Li2 notwithstanding.
