Timing could be better I suppose
Futurist Raymond Kurzweil (inventor of the Kurzweil synthesizers , renowned futurist and author of The Singularity Is Near) recently said something along the lines of part of your comment.
He said many now think widespread use of solar power is decades away from being cost-effective.
However , with the reality of 'accelerating returns' in various technologies such as nanotechnology and solar-film manufacturing technologies , he says that it will probably be more like only 5 years before widespread adoption of this method of power generation takes place.
In a couple of decades the world could be completely and cost effectively powered by the sun and other renewables.
That's potentially great news for all Earth inhabitants.
Many human-developed technologies are in fact just below the part of an exponential curve where the curve starts to go virtually straight up and we will soon see an 'explosion' of technological breakthroughs in all fields including space travel.
But .... times a'wastin' for oil/gas production 'going to be's' , as indeed there's no time like the present when it comes to getting it done.
