Steephie, if (and this could be seen as a big if) we use this energy win-fall to build huge numbers of energy intense solar harvesting devices (wind turbines, photo-voltaics, solar-thermal, hydro-electric, csp, and maybe some bio-mass processing) then we can kick-start an energy revolution, massively decreasing the cost of energy.
Which could in turn end poverty - where poverty is something akin to services available, you can use power to build homes, make food, run factories (which produce goods), operate electrical goods... - of course politics may make things complicated (by which i mean, in principle, people with power don't like to give it up)
