The best green technology is one that wins all on it's own without government life support, and the world will beat a path to that door way.
It's not so much which technology, it's that the government is interfering and distorting the market which is the worst. You always seem to end up with a worse solution and more expensive solution to the problem.
now for individual housing it is fine. they drill a hole and heat the water using the earths own heat.
Be sure to work hard and get lots of overtime. People on welfare want more steaks and free upgrades to smart phones with unlimited data packages.
