- | * more than a third of the total energy consumption of a Passive House can be covered by **hot water collectors** – because a Passive House requires more energy for the generation of hot water than it does for the heating.

- | * The remaining demand is so small that it can be met in a fully cost-effective way, e.g. by buying a **share in a wind power plant** – this has already been implemented in practice (example in illustration). | + | |

- | Due to the very high energy efficiency of the Passive House, there are increased opportunities for an adequate supply of energy though renewable sources. For one thing, the technical prerequisites are excellent: with low consumption **even minimal power supplies** are sufficient; and smaller power densities are a characteristic of renewable energy sources; for another thing, the cost-efficient implementation takes place in a better way: if the energy consumption is very low, the price for a kilowatt hour of conventional energy supply | + | Due to the very high energy efficiency of the Passive House, there are increased opportunities for an adequate supply of energy though renewable sources.
