Is anything really green?

I have pondered some issues concerning renewable resources. For many of the renewable sources that involve siphoning off some of the naturally occur systems (Wind, geothermal, tidal, solar, etc), would there actually be detrimental effects to the global systems in the long run.

For example:
Wind- If we are pulling out mechanical energy from wind systems; what impact could it have on weather patterns?

Geothermal seems pretty harmless, but tinkering with such volatile areas surely could have some detrimental side effects.

Tidal- While there are countless factors that drive ranging from various physical gradients, apply a turbine to drive for example might push the gradients into a different cycle or stall them completely.


What truly are the risks of tinkering with these systems?
