> Farmed trees are often promoted as being a great fuel, but they do very, very little for enhancing biodiversity.
Wind turbines and hydroelectric dams don't do much for enhancing biodiversity either, which is fine because their purpose is to generate electricity.

Only by counting burning biomass as emitting new CO2 while not counting the CO2 it removed from the air from being grown.
That only counts if you grow the trees explicitly for power generation. Burning trees that already existed (as is the plan for the plant I mentioned) is like burning coal, which also removed CO2 from the air in the past.
