Another technology I keep my eyes out for are Solar Chimneys. Basically you have hot air from green houses rising up the chimney turning turbines. All you need are plenty of space to build Kilometer tall buildings, and 16 hours of sunlight a day, which here in Australia we have nothing but. They've built small prototypes and Last I heard our parliament had allowed it, but I'm not sure what progress has been made since.

Edit: oh, and a year or two ago I read of Mechs being developed to use in construction.
