Energy abundance doesn't mean at a loss. It just means that excess energy that would go to waste can be used very cheaply, for all sorts of stuff that never would have been able to be accomplished before. Take CO2 extraction. It really isn't feasible, partially due to cost. But with free energy, it becomes more feasible (ignoring all the technical hurdles). Recycling becomes more efficient, all sorts of processes that are better for the environment but currently expensive will become possible.
