Incredible new statistics in this article, coinciding with a local news report of thousands of dollars per year in energy savings foer homeowners who install geo heat exchange heating/cooling systems.

I have been using the 36% figure for percentage of GHG from building heating/cooling, the 48% firgure  must be for lighting, water heating, cooking as well?

76% of electricity?  Incredible.

To me it's very good news, since the combination of solar cogeneration (heat+electricty from the same solar panels) and geo heat exchange heating/cooling could affordably eliminate that 48% and 76%.  Plus yield extra power for the grid.

Go Ed.  Maybe Brad and Ed could reprise their revolutionary duo in "Fight Club"?  But non-violently this time.  To sponsor a green building competition to come up with a cogeneration/geo heat exchange home as a building block for a distributed smart grid.

Buildings like this can feature energy storage as well as conservation (geo heat) and cogeneration.  By storing heat/cold in building mass and extra heat storage solutions.

That storage is enough to smooth out the power flow from a completely solar, wind, water, and biogas powered grid.  

The local news here had a feature on geo heat exchange heating/cooling saying it could save thousands in energy costs per year.

It showed the outdoor pipe loops being buried in trenches and the inside installation, it looked like a typical furnace.

Mass production will bring the price down.  And of course a per kwh saved subsidy would help consumers pay for these systems.  they directly replace fuel oil and natural gas heating and very energy expensive electric air conditioners.

by offering subsidies, taken away from fossil fuel industries, mass production would ramp up very quickly.  Stimulating the economy with savings.  And cutting down on oil and gas use.

Not sure about the percentages, but if lighting, cooking, computers, tvs, appliances, water heating, refrigeration, and so forth are all added onto heating/cooling, that extra percentage makes sense.

48% of GHG and 76% of electricity saved by solar cogeneration and geo heat exchange.  That would be sweet.
