Burning fossil fuels is bad because it reintroduces previously sequestered carbon back into the atmosphere.
Switching coal powder plants to burn wood would also shorten the carbon cycle from from millions of years to only decades....
It is still adding co2 into the atmosphere when we should be removing it.
Anything that adds more co2 to the atmosphere is not really helping.
Being stabbed and slowly bleeding out may give you a few more minutes of life than being shot in the head but you are still dead years before you should be.
