that's a lot. how about a deep pond below the top of the hill?

...60ft^2/r10 = 6 btu/h-f per freezer and 24h(80-0)6 = 11520 btu/day or
11520/3412/3 = 1.125 kwh/day or 3x26x1.125 = 88 kwh/day for the lot?
a 24'x24'x8' tall r40 frozen room with individual locked compartments
might only use 24h(80-0)1344ft^2/r40 = 64.5k btu/day, ie 6.3 kwh.

how about motion sensors as well?

...970 kwh/24h/33 = 1.2 kw, 882 kwh/mo, like an average us house.
how is water heated for showers?
