I am using one of these Acer netbooks (~ 8W) as a VOIP box and
to drive my TV. Because of the phone it is always on, like my
router, so I wanted low consumption. There may be lower consumption
devices than that available, but 8W is low enough for me.

Install solar panels. I did. Since hooking it up in January, I have
produced over half a megawatt more power than I am using, and feed it back
into the CPS grid for a refund check, or later use during peak usage. I
can monitor power production in realtime through my home network and
post it to the outside (check it out: http://220.127.116.11:5999/).
Besides the obvious advantages of reducing your carbon footprint and
getting free electricity, there are other benefits:
* solar panels shade your roof and reduce your energy needs for AC cooling.
* CPS gives you a rebate of $3/W installed, which is roughly 50% of your cost,
which is pretty amazing. I'd recommend to get it while this rebate is still available.
My installer took the rebate straight off the cost of the system, so I had no
out of pocket on that portion.
* The federal government gives you ANOTHER 30% tax credit on the remaining cost.
* The day you install it you are already ahead, because if you sold your house
the value of your house is increased by the cost of the system.
* The city cannot tax you on the increased value of your house, it is exempt from
* There is no captial gains on the portion of your house that is the cost of your
solar system when you sell your house.
* San Antonio is one of the best places to get solar power due to the high amount of
sun intensity (we are very far south).
* The system even produces enough power on rainy/cloudy days to meet my needs
* it is a lot of fun to watch your meter spin backwards, and getting zero $ power bills!
* and as you say, increasing electricity rates help me recover my investment quicker,
right now I figure about 5-6 years to be completely even.
