Renewable technologies are technically viable and economically attractive; traditional energy technology receives many investment dollars. This study examines the integration of renewable energy sources using functions that associate emissions with power generation; traditional producing units can represent these emissions. The environment friendly design has become a significant concern in the first decade of the 21st century. As a result of climate change and a limited supply of traditional energy sources (fossil fuel), the world needs to take renewable energy seriously. Renewable sources of energy are derived from the energy flow that occurs naturally in a continual manner. Many people define renewability as the ability to regenerate at a rate equal to or faster than a given energy source's depletion rate. Currently, fossil fuels are used to meet most energy needs, which should be replaced in the future by cleaner energy sources, such as renewables or nuclear energy. Building integration systems aim to replace a building element with a solar panel array to boost the RES system's viability. Renewable energy sources can be used to lessen the use of fossil fuels when certain criteria are satisfied. The use of renewable energy sources in buildings has well-understood environmental and economic benefits in this study. By relying on sustainable sources of energy, we can save as much energy as feasible.
