As atmospheric carbon levels, which cause global warming and threaten human life, approach critical limits, awareness on this issue has increased and applications for the implementation of new energy sources have accelerated. The search for solutions to reduce the rising atmospheric carbon dioxide levels as a result of the increase in industrialization and the burning of fossil fuels constitute innovative approaches for landscape designs. Landscape designs that aim to obtain their energy from natural, self-renewable systems instead of fossil fuels can be defined as energy landscapes. In addition to the use of resources such as solar, wind, wave and geothermal for the purpose of using renewable and clean energy sources in urban and rural landscape areas, the use of algae creates a great potential. When algae is used as biomass in the production of biodiesel, bioethanol and biogas, it provides renewable energy production by converting atmospheric carbon dioxide into fuel. It also has the capacity to capture about 20 times more atmospheric carbon dioxide per acre than forests. Micro algae, with their rapid growth characteristics, correspond to the search for new energy landscape methods by integrating into urban areas when produced in reactors and ponds. In the rural environment, commercial production areas where pools and reactors are used are becoming widespread, especially in large areas that are not suitable for agriculture, and in the urban environment, photobioreactor designs integrated into building facades and urban furniture serve renewable energy production.
