The problem with "renewable energy" is that so much of it is actually Biomass energy. 30% of Germany's renewable electricity comes from Biomass plants burning pelletized wood to the point that Biomass power generation accounts for 40% of all German forestry production. Biomass also accounts for 70% of all German renewable energy usage thanks to biodiesel and biogas usage, again almost all sourced from wood.

I guess the carbon cycle is relatively neutral as it's using existing environmental carbon plus some additional energy in the production and logistics process but it is unsustainable without turning every bit of harvestable forest into a monoculture of pine trees or fast growing deciduous with all the ecodiveristy of a Monsanto laced cornfield.
