It is made easier to incorporate renewable energy technology into the design and operation of buildings by the technological possibilities, techniques, and approaches that are addressed in this article. These building technologies include solar, wind, and geothermal systems. This article's goal is to provide a comprehensive study of the multiple technologies and alternative sources of energy that have been successfully adopted in order to reduce the amount of electrical and thermal energy that is required by buildings. These technologies and sources of energy include solar energy, wind energy, geothermal energy, bioenergy, and more. In this study, the methods that are applied for the integration of these technologies inside the structures of buildings are explored. Additionally, the importance of increasing the energy efficiency of buildings is discussed in this research. In addition, this article provides tips on how to properly implement programs that make use of alternative or renewable forms of energy.
