"Green" home electric bills

[Royal]

OK, some questions:

1. What other equipment is used in conjunction with the solar panels? Inverter, batteries, etc.? Would you need separate equipment for a turbine?

2. Who did the work for you, a contractor? Could this be done by the homeowner?

3. Goethermal sounds awesome, but drilling two wells had to be pricey. What did it cost? What above ground equipment is needed?

4. Finally, it might be easier to absorb some of those costs into a construction loan, but how costly and easy would a retrofit be?

I think about this all the time (for economics, not really for conservation), but it's not as easy as just slapping a few panels on your roof. Could you describe the whole system for us?
