The more energy usage increases around the world the closer critical situation for supplying energy will encounter the nations. There will no way remain except optimal energy consumption moreover finding new energy resources. Renewable energies nowadays are the core concern of many researchers. The scholars are trying to find out the new way of energy generation and also to know whether it is possible to reduce energy consumptions in the different sectors. Replacing fossil-based energy generation by other resources of renewable energies like wind and solar are started in the past decades.

A system approach is applied in this research to present a model to analyze how building architecture and constructions could be improved toward green energy usage. Renewable energies will increase the incentives of the environmental protection, clean supply and demand in the huge energy consumers’ sectors like industries.

It is concluded that environmental issues are a matter of concern for people, they cannot tolerate the higher expenses of green energy generation. They prefer to use cheap energy resources mainly non-renewables. The model confirmed the supporting policies both to generation and consumption will dramatically improve green energy usage. The governments can support both supplying and demand sides to decrease their energy expenses and give the people some incentive to use renewable subsidized energy and also earning by selling their extra generated power to the grid.
