Energy Enhancement Rundown

Here is a review of all the energy enhancements I have applied to my home.

1.  Home was originally built with Low-E windows and R-49 attic loose-fill insulation. I inspected the insulation after I moved in and it was "shallow" in some areas and so I had them come out and spruce it up.  I gave the installer a $20 bill to get a "little extra" here and there.
2.  I have always only used CFL bulbs and/or LED bulbs since move-in day in April 2004.
3.  I installed ceiling fans in the living room and master bedroom, and I use them when I'm in those rooms.
4.  I tinted some internal windows myself, and had a company install Hüper Optik tint on some of the other windows.
5.  I paid $1600 for radiant barrier foil sheets to be installed in the attic.  This slows the progress of heat build-up in the attic and allows the two solar-panel-powered attic vent fans to eliminate much of that heat before it gets into the livable portions of the house.
6.  I paid $800 for two solar-panel-powered attic vent fans.
7.  I painted the inside of my garage door with ceramic-infused paint to block heat.  It gets late-day western sun.  I also applied insulated heat-reflective foil to the inside of the garage door.
8.  I paid $3700 for an "Energy Management Computer" which controls how much On-Peak air conditioning is allowed to run.  This saves about 15% on energy bills by allowing me to pre-cool the house during Off-Peak hours and then running the A/C very sparingly during On-Peak hours.
9.  I bought an AirTap "heat pump water heater" from a company named AirGenerate.  It mounts on top of your regular water heater and uses a compressor to extract heat from the surrounding air to heat a copper tube inserted into the top of the regular water heater.  As a part of that installation, I replaced my regular electric water heater with a Marathon electric water heater, which is better insulated and far more efficient than a regular water heater.  I added a timer to the AirTap and only run it during Off-Peak hours.  This setup cost me $2100.  The heating elements on the Marathon are not even turned on.
10.  As a part of the home purchase, I had faux-wood blinds installed on every window in the home, as well as dark sun screens on the outside of the windows.
11.  All the appliances I bought with the house are Energy Star rated, including the front-loading Whirpool washer and dryer set.  I dry my clothes on the "extra low" setting, and always wash with cold water, using "Cold Water Tide" as my soap.
12.  I bought a Spin-X spin dryer back when I had a regular washer.  It spins clothes at 3500 rpm and removes a lot of water from clothes between the washer and putting them into the regular dryer.  I also have a drying rack in the garage I use for many of the clothes, and that reduces their drying time even more.  The washer is large enough that I only have 3 loads per week.
13.  I immediately installed a programmable Hunter thermostat, which allows me full control over when and how the home is heated or cooled.  This reduces wasted cooling or heating time.
14.  Solar panels on the roof through Solar City.  This will allow me to generate somewhere around 85% of my electricity from the sun.

So.  That's what I've done.  Why don't I have a net zero usage home?  Good question.
