This paper reviews the achievements and the progress of the renewable energy technology in the past 70 years. Since the founding of the People's Republic of China, due to the lack of energy, China has attached a great importance to the development of renewable energy such as the biogas and the hydropower. By the early 1990s, in view of the pressure of the energy security, the environmental protection and other factors, China began to further strengthen the development of renewable energy such as the solar energy, the wind energy and the biomass energy. The technologies of the biogas and the hydropower in our country have reached the matured state earlier and are at the forefront of the world at present. Other renewable energy technologies, such as the solar energy and the wind energy, have gone through the development process from the technology imitation to the creative imitation, and are now at the key point of turning to the independent innovation.
