While the use of some renewable resources may save energy, the fact that a particular resource is renewable is not a guarantee that using it will save energy. The value of a renewable resource is not in energy saving but in the fact that it is renewable and so can be used mostly without fear of excess carbon emissions, and without concern of it being used up and unavailable for future generations.
