By fossil fuels industry, I presume you mean the coal industry? The Oil industry has little to nothing to do with us not using wind and solar more. Oil isn't a primary source of electricity generation (1%). Natural Gas is about 25%, but even with wind and solar, the need for natural gas plants won't go away.
Personally in my opinion, we should have more Nuclear power for electricity generation, and then we should go to Natural Gas for transportation energy in the short term, until we can figure out better methods. Possibly the long-term solution for vehicles could be Hydrogen, once we work out the issues with on-board fuel storage, cost, and hydrogen production.
