Here's the real problem. A given standard of living requires a specific level of energy. The only truly renewable sources of energy we have - as in 'will last as long as the planet could remain habitable' are tidal, geothermal, and solar (which includes wind and hydroelectric, as they are themselves solar powered). Nuclear will run out. Fossil fuels will run out. IF we get practical over-unity fusion going, that can go on the renewable list, too.
Ultimately, you need a certain amount of surface area assigned to energy collection per person, and it's not tiny, especially as you get further inland or further from the equator.
