You learn to get smart about your power consumption. When I sold out and moved to town my electricity bills were way less than any of our neighbours or friends. You get accustomed to conserving if you are generating the power.
Well, exactly. "DVD night" won't be the night at anchor after a rainy day with no wind, but after a sunny day with a decent breeze. Underway, I am happy to motorsail in order to charge on the go, and to compensate for the drawdown of occasional radar and communications use, like SSB, weatherfax, AIS, etc.
The ONLY constant draw will be the refrigeration. Everything else will be either intermittent or low-draw. We can get hot water via the inverter, of course, but in the tropics, a black five-gallon pail filled with fresh water and sealed inside a black garbage bag on deck will get ridiculously hot in a hurry. We can also simply schedule laundry day for the times when the heat exchanger fills the hot water tank with "free" hot water.
Much of energy wastage is due to poor scheduling, I think. Thanks for the comments.
