How much power do you need?

Is it really a need… or what?
The reality is more likely about convenience and/or comfort.

Living a Simple and Sustainable Lifestyle.

Many people, living modern lifestyles, will use as much as 30KW/h per day, in a few cases even higher than that.  Though how much power do you really need to keep all your modern conveniences?

Truth be told you need a lot less than you think, if you are willing to downsize your living space.  Lets go through everything.

Total Usage (nnKW/h per day):

We will have to include conversion losses.   while some things are 12 volt, and thus minimal conversion losses I still calculate high by calculating inverter loss in with everything.   It is always best to figure high so you will have enough power.   The conversion and transmission losses on solar include (in most cases):

  • Inverter Conversion, about 15%.
  • 18 hours per day from battery, so storage losses 10%.
  • Transmission loss 10%.

So we figure high and say 40% overall loss, thus requiring 1.8 times more production that…

My blog, My way Welcome to a little piece of my life. Here you will find things concerning my everyday experiences and or my thoughts on everyday happenings. For instance you may find thoughts of my Farmstead, which is as my wife calls it, our Accidental Farming life. Perhaps on a whim, I might just jump on a soap box about what's going on with my crazy family (the immediate one, that is).~You don't need to put a penny in the coin slot for any commentary there~ You may find, new additions to what I call "Hobby-time". Ahh yes, my hobby... I make pinback buttons (some call them badges). Sorry for the shameful plug ;-) *** And then there is the outside the box or "Offtrack" thinking, part of me. Which can be anything else from aliens to the zoology of the Loch Ness monster, but will probably be more mundane as health concerns, for instance, to vaccinate or not. Is the Earth Flat or is it Hollow? Is there a dome? Is any of it real? Do you really want to know? Police brutality and the continuing corruption of established government, Big Business, Big Oil, Big Brother. Can we survive? Should we survive? The coming montrary collapse. There is so much going on, more then we see outside our windows.

    1. Yes, it really is a practice question. It is better to have a surplus of power than a deficit.
      Once I lived in a dwelling not much bigger than a 6 person tent, and you’d be surprised how little power a person actually needs on a day to day basis (I used a 45 watt system then). Now, I am married w/children and my needs/wants are much greater.
      But, the power demand… is it a WANT or is it an actual NEED?

      Still, at the end of the day, the reality is having MORE is always preferable.
