To mitigate the present climate crisis, the global community must achieve a large-scale, sustainedreduction in greenhouse gas emissions, by moving away from a predominantly fossil fuel-basedeconomy to one dominated by renewable energy. The Sustainable Development Goal #7 (SDG7) of UN,‘Affordable and Clean Energy’, has been set up to facilitate global challenges in the fast developmentof modern renewable energy systems.
