Gas stations, tanker trucks, oil pipelines, ect

These are big reason for the push back also. Companies have spend hundreds of millions if not billions of dollars building the infrastructure for fossil fuels and they will fight for keeping those investments alive.

Another thing slowing down clean energy is that wind and solarpower arent yet as reliable as coal power. Cities and nations can calculate how much coal or fossil fuel they need to keep lights on and stockpile fossile fuels for future use easily and they work even if there is no wind or sky is cloudy.

Hydroelectric is renewable and quite reliable, but its not neccessarilly good for enviroment either. Geothermal would be great, but its really expensive and its not possible to harvest everywhere in the world.

My personal opinion is that nuclear power with auxilary solar, wind and hydroelectrics would be best compination. Especially since battery technology is currently taking big leap with solid state batteries and it seems we might soon have electric vechicles with reasonable range. Even more so if the new batteries are as safe as manufactorers claim and in case of accident there is less of an risk of the unholy hellfire batteryfires are currently.
