Additionally, the energy conversion and storage system can in the near future be optimized for neighborhood heating and electricity grids, not only for the greenhouses but for whole neighborhoods. Shared greenhouses provide space for food growing, community building, knowledge sharing and new opportunities for businesses and services.,Shared greenhouses are an innovative concept that can potentially increase urban food production bringing enormous benefits to the citie’s in air quality, food supply, and community building.
