    Well right now we bulldozer massive parts of the desert for coal that is used to power steam plants for electricity- I'd rather more solar farms than massive pits in the ground with their massive mounds of waste.

    That said I never liked the all or nothing approach- be it the method of powering the production to location of production. Having houses that help reduce the need for power shipped in from afar sounds great, but so does a few massive solar/wind farms. There is a tipping point between economy of scale and lost in transmission. One thing that was tested and seemed to work out here is co-gen. The local drywall plant gives off massive amounts of steam as part of the process. The local electric company fought for years but finally now accepts electricity made from the waste steam into the grid. by no means a solution to the energy problem but I think part of our problem is we don't see a need to be efficient.

    I think that is what President Obama meant by making power cost more- when something is dear we tend to economize as well as look to less spectacular solutions. Scavenging power from waste isn't glamorous, but could be a lot more profitable than bigger and deeper holes in the desert for coal.

I've seen a setup where they had no underground but set up passive swamp cooling at floor level using the wind tower air draw. Worked pretty good for only the small water pump power.
    I WISH! The wife is too afraid of creepy crawlies coming in. (yeah I know but try and tell her!) Well that and the possibility of a dank or moldy smell if moisture builds up in the pipes.

    Wind power just isn't practical in my area. the 270 or whatever it is AGL average wind speed doesn't make it feasible or reliable. Maybe if people were to install smaller do it yourself kits they could pick up some marginal savings on windy days or if solar kits come down in price they could do the same. The market has really adjusted on the efficiency side with appliances and insulation as they are common sense, consumer friendly affordable choices. Right now none of the personal generation systems really fit that bill other than perhaps the external wood furnaces but they are still like $10K and require lots of wood.

    The argon (?) gas between the panes adds very little to the price. In a demonstration with a heat lamp, the difference was significant. Well worth the extra 10% of cost. Plus, lifetime guarantees including breakage sealed the deal.

    "Green type" or not it's a relatively simple question.

    Bigger, less efficient, 1990-ish style house

    -or-

    Smaller, extremely efficient, 2013 technology

    I don't want to disappoint you but the lifespan of those photo-voltaic panels is about 25 years, so probably they won't last much longer than that.

    I realize that. They will probably be outdated. No big whoop.
    No men are anywhere, and Im allowed to go in, because Im the owner of the pageant and therefore Im inspecting it, Trump said... Is everyone OK? You know, theyre standing there with no clothes. Is everybody OK? And you see these incredible looking women, and so I sort of get away with things like that.

    Theyre good, but the gas leaks out over time.

    Low-E coatings are also good but don't work for passive solar, better to use roof shading to keep sunlight oit in the summer.

    And aren't likely to pay for themselves over than lifetime. It isn't just an environmental issue. It is also an economic one.

    I'd rather see less of both and roofs across America with solar panels on them.
