That's more of a management problem than a renewables problem. Coal and oil are several orders of magnitude slower than old-growth forests.

If you're saying that without the renewable energy credits that the deforestation rate would be slower, then that's a positive that would have to be weighed against what I asked about.

If the lack of energy credits don't have an effect on the rate of deforestation, then it could be worse for the environment than maintaining the status quo. If the deforestation is the problem then work on directly stopping it through legislation.

Actually no. All the coal in the world comes from one geological time. When trees first evolved into being they were very successful and forests spread over a large areas of the planet. Being so relatively new, nothing had evolved to decompose fallen or dead trees, so they simply piled up. Over time, this layer became coal. The micro-organism free environment will never exist again, so coal will never form again.
