Energy Autarky of Households by Sufficiency Measures

A consciousness about being independent from energy suppliers is spreading due to several reasons. Many authors already analyzed PV battery systems with a focus on the grade of autarky and self-consumption. But what if someone wants to be autarkic? With what does the person have to cope with and how can it be influenced? To quantify these questions the sufficiency indicator is introduced. It describes the qualitative rate of self-sufficiency and involves personal ratings of devices. With its help the effect of the sufficiency measures “shifting” and “prioritized shutdown” on the contentment of households is quantified.
