Also, this study discusses other kinds of energy especially renewable energy
such as wind, solar, biomass and geothermal as the alternative for energy supply in this country. It is
found that, since the country has many windy areas and at least 2800 sunshine hours per year, it has high
potential for utilizing wind and solar energy. Therefore, Iran must try to optimize energy consumption
especially in the residential sector and increase the contribution of renewable energy in energy supply
to make the energy mix secure and environmentally sustainable.
