Some technologies for using renewable energy have made great progress and reached a certain scale in the world. Utilization technologies such as biomass energy, solar energy, wind energy, hydropower and geothermal energy have been applied.
The International Energy Agency (IEA) conducted a study on international electricity demand from 2000 to 2030. The study shows that the average annual growth rate of total production of Electricity from renewable energies will be the fastest. IEA research estimates that over the next 30 years, non-hydro renewable energy generation will grow faster than any other fuel-based electricity generation, with an annual growth rate of nearly 6%, and that its total electricity production will be multiplied by five between 2000 and 2030. By 2030
It will provide 4.4% of thethe world's total electricity, 80% of which comes from biomass.
The Chinese government attaches great importance to the research and development of renewable energy. The State Economic and Trade Commission formulated the "Tenth Five-Year Plan" for the development of new energy and renewable energy industries, and formulated and promulgated the "Renewable Energy Law of the People's Republic of China", focusing on on the development of solar thermal energy. utilization, wind power generation, efficient use of biomass energy and use of geothermal energy. With strong state support, China has made great progress in wind power generation, tidal power generation and solar energy utilization. New energies (or more precisely renewable energies) mainly include: solar energy, wind energyienne, geothermal energy, biomass energy, etc.
