Ok, so I'm new and I'm learning!  In retrospect my initial power usage estimation for the temporary shelter was a little extravagant, to say the least.  After moving through it all again with a fine tooth comb, I have reassessed my most essential needs and radically reduced my estimated power usage.  These new estimates put me a little over 1000 watt/hrs per day, roughly half my original estimate.  To achieve this, I have removed the refridgerator, microwave, juicer, TV, and coffee maker.  In the chart, the items have just been set to 0/days per week.  Here is the revised temp shelter load analysis work sheet.  I will post a revised load analysis sheet for the final shelter when I get to that stage of the project.

One important note on computers... if you are looking to live off-grid, consider a laptop (if it must be Windows-based, one with the new low energy consumption Centrino chip is best), or if you need a desktop, you would do yourself a huge favor to consider purchasing an Apple Macintosh with an LCD monitor.  The RISC chips in Apple computers run at less than half the power consumption of a comparable PC, with an instant-off sleep mode that consumes less than 1 watt, and no-surge instant-on.  Very soon, however, Apple Macintosh computers will begin using an IBM chip called the PPC970, for even more impressive energy savings.  The 970 chip promises to run at 1.2 Ghz (approximately equivalent to a 2.6 Ghz Pentium) while consuming only 12 watts of power!   Over time, this will add up to an enormous energy savings.
