Solar power putz's

The Nytimes has an article today about how solar power still doesn't
make economic sense. They use an example for a house with a system
that costs $54000, which to me seems excessive. The only way solar
power will make sense for anyone is to first cut down the demand side
of the equation, you can't solar power conventional air conditioning!

I took a class a few years ago on designing and installing PV systems,
and I learned from that class that it is possible to either be a shark
and screw people out of a lot of money and sell them things they don't
need, or you have to live like the instructor did, in a crappy 30 year old
camper. The 3rd way to live would probably entail me continuing to work
in the oilfield while selling PV on weekends.

To me, the people that installed a $54000 system are sharks. A rule of
thumb would guestimate a pv system costing $15/watt installed. So a $54000
system would be a 3.5 kilowatt system, and if New Jersey gets 4-5 usable
of sunlight per day, then they would generate about 505 kwh/month,
to try and meet the demands of a macmansion.

The better way that makes economic sense is to cut back on electricity usage,
use gas for heating, cooking and drying. Then replace all lights with florescents
that it's possible to put up with, then cut out all the thief loads and turn off
TV's, vcr's and computers that aren't in use with powerstrips. Every watt
you save on load saves you $15.

In New Jersey you could probably live without air conditioning, in Houston,
not so much. In order to try and be green in Houston you'd really need a
ground loop heat pump, which is probably the most cost effective thing
to do in areas that need aircon.

The ideal isn't just to spend money to propitiate the green gods [A la al gore]
or to live in caves without internet, but to sensibly cut back and save energy and
money, then put up a PV system that will cover the load.

almost everyone i have heard of who lives off the grid does so in a modest sized house that is mostly passively heated and cooled. they also use energy more wisely and match usage with solar power generation times. that seems to be the only way to go at present.

I love solar power I think over the next few years it's going to be exploding even more... as performance of solar panels goes up people are going to be adopting it everywhere they can... after all it's free energy :) BTW here is more solar power information -> Solar Power

Another clue Lowe's is the good one::::Katrina cottage plans.
In this era of preditory developers building massive new homes (ie SUVs) it is quite refreshing to see Lowe's promote modest single family structures.
Looking in Denver these are the kinds of homes I am looking at. To move into a brand new structure would be key, especially in Denver:::::Full insulation, no dreaded leakage leading to high heating bills. No ghosts and no history.
As with all things::::Redwhite&blue IS BAD FOR YOU!!!! Much like some Walmarts, some Lowe's stores are redwhite&blue color scheme:::Assume its a clue that these towns are disfavored and it would be wise to GET THE FUCK OUT!!!
Bet that Oldsmobile was the only good American auto manufacturer left and now they're gone.

The 80s era of M&A and integration with/controlling interest by evil entities has eliminated good from the marketplace.
In this era of Manifest Destiny positioning the gods have the preditory disfavored steal from the good disfavored::::
1. Microsoft stole Windows from Apple Computer/SteveJobs/Wozniac
2. Alexander Graham Bell stole the telephone from Elisha Grey
3. Waffle House's business model was stolen by many entities who copied the style and stole market share. HOLDING BACK THE COFFEE IS A TACTIC THE GODS USE TO SEND THE DISFAVORED ELSEWHERE and a clue they are good::::Coffee is bad for you.
