High efficiency fluorescents aren't. We have them in our house, and we have yet to have one last more than a year. The claims are inflated at best.

LED and LED Film lighting will be where high efficiency lighting truly comes in. (As to the LED film, imagine being able to paint your ceiling with a material and have it give off light. Over simplified, but it's being worked on)

Our house will eventually go to an on grid solar system, but that's a few years off.
