Strom und Wärme selbst erzeugen

How to make your home energy self-sufficient

If you make yourself independent of energy suppliers, you can face rising energy prices with confidence and start your own energy revolution. In principle, sun, wind and environmental heat are available as energy sources. But how can they be utilised efficiently in order to become as self-sufficient as possible in terms of energy supply?

• We explain the technical possibilities: for electricity and heat generation, energy storage and hybrid systems.

• We use three example households to illustrate the implementation: for renovated and unrenovated existing buildings and for new buildings.

• We show which technology is most suitable: photovoltaics, solar thermal energy, combined heat and power units, heat pumps or wind turbines. And how the combination of technologies makes even more self-sufficiency possible.

• We provide the necessary key figures for the technology variants: Investment and operating costs, amortisation period, CO2 emissions and degree of self-sufficiency.

• And with the interactive tables that we offer online, you can calculate whether your own desired supply is economical and climate-friendly.

• With many sample calculations and checklists

Five steps to energy self-sufficiency

&bull, Step 1: Determine and evaluate your current energy consumption

&bull, Step 2: Check which energy sources are available and which technologies can be used to utilise them

&bull, Step 3: Using examples, determine what results these techniques can bring

&bull, Step 4: Apply these results to your own property using the appropriate conversion factors

&bull, Step 5: Achieve the greatest possible independence by optimising the use of the techniques

Numerous new technical systems make it possible to achieve an economical result when generating your own energy.
