>>1155800>"normal life"That's extremely subjective. My electric bill states my usage is around the 250Kwh to 450Kwh range per month. When I had a live-in girlfriend, it was over 2Mwh per month. I'm not really trying to use less electric, but I am certainly not actively wasting it. I also keep everything unplugged unless I am using it or like the fridge it needs to be on. Here's a list of my devices:
Gaming PC: 600watt PSU
Monitor/TV:204watt
Sound System: 200watt
Various electric cookware (toaster, toaster oven, sandwich maker) that I rarely use 1kw - 2kw
Box fan
Ceiling fan
Fridge
Lighting: LED, CFL, & FL
Obviously, my largest usage is the PC being on several hours a day. On the rare times I want or need to save money I will break out my 32watt netbook and use it for shitposting, movies, and porn instead of the huge PC. That usually gets me into the 50-100kwh used in a month range.
You should get/make a wood stove. They are great.
>What is the minimal offgrid electric consumption one could reach ?0kwh/month
Heating: wood stove
Heating water: wood stove/solar
Use coppacing and pollarding for your wood fuel needs. That allows the same use of land without the need for replanting. Also, you can harvest the wood when it is the right diameter so you don't need to split it. For solar water heating, only use a passive system. In cold weather areas where t he water freezes outside, use a 2-part system that has an antifreeze loop for the outside. The sun heats up the outside loop and a heat exchanger inside transfers that heat to your insulated batch heating water system for later use.
