 The Passive House is a perfect example for this:  The Passive House is a perfect example for this: 
   * more than a third of the total energy consumption of a Passive House in a typical cool moderate climate 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. Thermal collectors are the best solution for the provision of hot water. (The figures are even better in warm moderate climates and in "lucky climates like California: it could be 50% to full cover.)   * more than a third of the total energy consumption of a Passive House in a typical cool moderate climate 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 in Passive Hosues that it can be met in a fully cost-effective way by renewable energy, e.g. by buying a **share in a wind power plant** – this has already been implemented in practice (example in illustration).   * The remaining demand is so small in Passive Hosues that it can be met in a fully cost-effective way by renewable energy, e.g. by buying a **share in a wind power plant** – this has already been implemented in practice (example in illustration).

   * **Photovoltaic systems** can also contribute significantly to the supply of energy //in Passive Houses//. But let us be honest: The contribution of photovoltaic systems to "​ordinary"​ inefficient houses with high consumption values is no more than a "fig leaf"; but Passive House efficiency makes the difference.\\   * **Photovoltaic systems** can also contribute significantly to the supply of energy //in Passive Houses//.
