Our organization always appreciates environmentally friendly activities. The global demand for energy is increasing as a consequence of industrial development and population growth. Dependence on fossil carbon-based energy with greenhouse gasses emissions causes major environmental problems. Thus, we should widely encourage sustainable energies to use because they are available without any expenditure. And most importantly, helps us reduce greenhouse gasses emissions and causes minimal environmental damage. Solar energy, wind energy, geothermal energy, bioenergy, hydropower, and ocean energy are different types of renewable energies. To make appropriate predictions, and investigate the process of using and implementing renewable energies in different applications, CFD simulations are of great importance. CFD simulations will help us model airflow around wind turbines, waves, air conditioning in the buildings, heat pump, etc. Therefore, we can save money, and engineers can develop their designs basedwind turbine on the simulation results.
