Generally I have been replacing with cfl as bulbs burn out. The bulbs themselves have a certain amount of energy cost if you simply replace good ones. I have found that there are places were this is impossible such as with some fixture designs or were the socket is small. I also have found that the lifespan of the cfl has been less than advertised.

Regarding geothermal, one of my clients is in the business. Generally you get about a fifty percent reduction in energy consumption for heat and AC at least in the area I live in Southern Ontario. After you get through the overburden about 50 to 100 feet around here you can support about 1500 square feet of living space for every 100 ft you go down either in separate holes or deeper holes. The circulating pump is attached to a heat pump.
Regards
