As oil prices have plummeted, the question has naturally come up: does this mean the end for renewable energies? Can they compete with this cheap fossil energy? The short answer is: yes, it will of course now be less profitable to invest in renewable energies. However, paradoxically, the longer story is more complex. Wind energy is already competitive with fossil energy, and solar has also passed the break-even point in more sunny places. And unlike non-renewable energy sources, the long run trend is towards falling costs. So we may be at a turning point for the fossil energy.
