And for cryin' out loud, we (the world) are not running out of cheap, abundant fossil fuels.
Yes and no. Both crude oil and natural gas is being used up faster than new sources are being discovered. While the tar sands in Canada and Venezuela hold a lot of potential feedstock, extracting it is both energy intensive and expensive.
True there is a lot of coal and coal-to-liquids is a possible solution to the problem of replacing liquid fuels it produces far more CO2 per unit of fuel tha current production does. Even discounting CO2 emissions the energy returned on energy invested isn't nearly as good as conventional oil and gas (the same holds true for the tar sands)
In short energy is going to get a lot more expensive for the use cases most people care about. This is going to make everything more expensive including still relatively abundant coal, building nuke plants and making the fuel, and building infrastructure to make greater use of renewables.
