Public buildings, rural town halls, hotels, etc., as well as private dwellings, located in rural areas, can house generation elements that allow profitability to be obtained from indigenous renewable resources. If there is electricity consumption, the energy generated can be used to meet the demand itself. If there is a generation surplus, it can be sold to the distribution network, obtaining an economic return, or a zero injection system can be implemented to avoid dumping.

In any case, the incorporation of renewable generation will make it possible to reduce or offset greenhouse gas emissions, or CO2, thus reducing the impact of the building’s carbon footprint.

The roofs of buildings can be a suitable location for installing photovoltaic panels. If the location of the building is windy enough, wind or mini- wind generators will be indicated. The first step will be a study of the renewable resources available on the site, followed by the corresponding diagnosis of profitability, including the most economical dimensioning. Each case is different and renewable generation facilities will be much more profitable if they have been specially designed for the situation.
