Even if one loves fossil fuels, and hates renewables, surely one must acknowledge that coal / gas / uranium / (insert next minable resource) WILL run out.
Maybe it'll take 1,000 years.
Maybe a 1,000,000.
Maybe we'll kill ourselves (mankind) beforehand, but:
For one to entertain the idea of mankind outliving this point in time you have to imagine one of two possibilities:
1) We build systems and processes for surviving / living / thriving based solely upon the energy earth receives from the sun, and or earths own internal heat.
2) We source fuels extra terrestrially - either bringing them to earth, or moving ourselves to the location of the fuel.
We can talk about nuclear, or carbon sequestration, or how the challenge of producing a viable base load solely on renewables is till we’re all blue in the face, but in the end, I don't think mankind has a lot of choice in the direction. Just a lot of time to waste until we’re forced to agree.
