ABSTRACT
				Nowadays, clean energy has become a hot topic, and many countries have approved new policies on clean energy. In this research, we would introduce different types of clean energy, and discuss the positive relationships between clean energy, production, and productivity. On this basis, we will further clarify the important role that clean energy in the development of Gross Domestic Product (GDP) from the expenditure approach. Last but not least, we would give suggestions on global cooperation on clean energy.
