Technology? Sort of. For the mass amounts of energy that would be required we're talking superconductive materials, the possibility to store this energy, and the methodology of transporting this energy to ground level.
Now after technology you have other things that affect decisions of things like this. Economy, share holders in current energy markets, systematic buying and then repressing of technological patents to increase market outputs of current energy sources, fear of the new, etc..
The best thing I can tell you is that if you think it's something that you can propogate, do the foot work. Don't wait for things to happen, make the first steps yourself.
