If you are a firm believer that we'll be out of fossil fuels long before solar or electric via solar become economic though - by all means - make it the whole world in that case. I don't know if I really want to get into that debate whether or not I believe that will happen, I have reservations, but regardless staying on topic - what do you see happening if the whole world collapses in your opinion?
The main problem is a simple observation I first read about decades ago in an old used university physics book. Namely, a 100 years ago the book made the claim that all fossil fuels are gone once they are used, and it took a little less than a billion years for the fuels to form, and the fuels aren't coming back. The book expressed the view that fossil fuels were much more valuable for chemical uses than the simple burning, and/or distilling them and then combusting them, for heat expansion.
The book's viewpoint on which use to put the fuels to wasn't taken, and industrialism continued full-speed ahead with the internal combustion engine and fuel powered steam engines. All the warnings were taken as if they were like the warnings of the decreasing supplies of whale oil, in that, by the time any supply becomes critical, a great new idea and source of another fuel will be available as a replacement. Compared to the value of coal and petroleum, all of the great "new" ideas have been with miniscule results to total failures. Plastics and fertilizers did become an important chemical aspect, but the simple burning remained the largest level of consumption.
The fossil fuels now remaining have much lower energy values (and a great proportion of the energy must be expended to get the remaining energy out (this wrecked farming for ethanol production, because very few lands on Earth "grows" more energy than the energy put in with industrialized farming practices). The declining energy values of the fossil fuels are going to decline near geometrically, and the side-effect of burning greater and greater proportions of the fuels retrieved to retrieve the remaining fuel for obtaining the usable output, is going to consume oxygen in exponentially higher rates, which is also going to reduce fuel burning efficiencies. With concepts like "Hubbert's Peak", the amount of fossil fuels per person per year is going to decline with out a tremenous increase in the losing of larger and larger proportions of the energy in making the energy available for consumption. The choice is with either declining consumption levels with a slow failure, or maintaining consumption levels with a fast, and probably abrupt, failure.
All other energy sources are very limited, and increasing these sources require tremendous energy investment to get them started, and heavy energy investment to maintain them, making them energy expensive with minimal resultant output (solar powered steam engines were tried a couple hundred years ago, and they were big enough failures to make wood and coal to remain "tomorrow's energy"). Windmills are good, but put up a few too many, and the wind is going to blow somewhere else or not at all (about like water following the path of least resistance (and with dust instead of silt)). All the other energy sources are miniscule, and all large scale attempts have the "perpetual motion machine" problem, in that something always prevents them from working (but the "working" on the small-scale is a perpetual temptation), and total usable energy out is always less than the usable energy put in on bigger scales.
The most energy efficient social model was described by Peter Farb (search books-dot-google for "Peter Farb Shoshone" for many sources, or "Peter Farb Shoshone Calorie" for 3 or 4 books). Different calculations with such models have pessimistically placed the World's sustainable population without fossil fuels at just 250,000,000 people (other sources place a fossil fuel/population peak of ten billion people, so by those numbers only one person out of 40 is going to be sustainable at fossil fuel failure). But, with zero fossil fuels and few people, the maximum work day is only a couple hours long, so how did advancement and living in luxury result in a 40 hour work week???
Well, maybe Santa Claus will give us Cold Fussion for real, instead of all the flim-flam con jobs.
