I'm not sure if everyone realizes this, the more we are with the "disposable" consumer mentality, the need/reliance on petroleum products still exist. All plastics are derived from oil/gas. Many chemicals as well as consumer products also are derived from oil/gas.
The roads are paved with asphalt, which again is a by-product of the refining process. The interim "clean" form of power generation next to Nuclear is Natural Gas, so there'll still be a demand for that.
With all this hoopla on how bad O&G is, people don't seem to realize that the electric vehicles they're buying is many times more toxic to the environment as a whole than a petroleum powered vehicle. (inclusive of origin material and post use recycling).
PV is not to the point where it's feasible on wide-scale replacement of other forms of renewables. In fact, PV is negatively affecting the markets for electricity, as there's an over-supply when the demand is naturally relatively low, and does not add to the grid when electricity is really required.
