I don't think it only affects the existing members of the energy sector. Given the necessary financial motivation, there is a realistic opportunity for new competition in the renewable energy market rather than only relying on existing stablished companies to shift focus. Even if a group wants to move in to the renewable energy market on principal, funding will be a lot harder to come by with super cheap fossil fuel prices since investors (who are also motivated by money) won't see as much potential for short term profits.
