independent of the grid ! (none / 0)
Amen on that.

If you are building from scratch or fixing up, that is a differnt story. The ROI from good building practices, passive solar, grading and plantings along with some geothermal HVAC will limit the amount of energy you need by 75% +/-. Geothermal alone is a better investment than solar, at least where I live. At some point I will upgrade that as well.

Just think if IBM or Intel had put as much into solar as they did computer chips......

There are lots of things more efficiant than solar (none / 0)
I've already added Argon insulation, as well as a few other things.  I need to look into geothermal as well as a few other things, too.  However, I'd like to know when you guys did your statistics how much were you paying per watt of solar paneling, and what was the cost of energy at the time?

when i did it. (none / 0)
i bought my stuff... hmm let's see 3 years ago? it was much more expensive. it was like 900$ per watt canadian. which is something like 700'ish american? or so. it was very expensive, wind power i dont remember exactly but it was at least 50% less expensive then solar.
