It's not a good solution to energy shortages if there's any chance of making a place unhabitable. Defeats the point really.
As for renewable, most weather elements can be taken advantage of if the means to do so occurred. Wind, sun, waves, water. And it may not be good enough to be a universal solution yet but it should be good enough with time.
Not only that but we need to make ways of getting energy more efficient, it's just far too wasteful right now

Not sure what kind of a solution renewables might be: renewables won't simply compensate the difference if hydrocarbonates are no more, wind and solar energy EROEI is substantially lower than oil and gas while hydro is almost ran out of any capacity of growth, besides we yet to see the profitability of solar and wind energy industry when costs will rise sky high if there'll be no cheap oil around -- aside hydro renewables are merely a leach that suck out blood out of hydrocarbonates, no cheap energy = no renewables (almost). What else we've got? Well yes, tidal power plants might be more common in the future, there's potential of growth, but at this point in time there's not enough investment into really worthwhile projects like Penzhina Bay TPP (afaik the project has been discussed since late Soviet times and never realized). All in all renewables are hocus of green politics and parties.
Can't say nuclear power is a savior her too, the rate at which new NPP blocks are comissioned is absolutely unsatisfactory. When Hubbert was drawing his Gausian curve of fossil fuels production rise and decline he thought that nuclear energy will pick up to compensate for steady decline. But it didn't, which makes it harder for us to maintan current level of oil production and increasing our chances that this tranist to new energy source might be more abrupt with all fancy effects of such transition -- poverty, famine, wars, population decline and so on and so forth.
