    During the "14th Five-Year Plan" period, under the conditions of ensuring energy security, achieving a green and low-carbon transformation, promoting the construction of ecological civilization, and responding to climate change, it is necessary to further understand the situation and tasks
    facing China's renewable energy development。

    There is still a lot of room
    for development in hydropower。 China is a major hydropower country in
    the world.
    Since 2004, China's total installed hydropower capacity has continuously ranked first in the
    world.
    By the end of 2021, the country's installed hydropower capacity will be 391 million kilowatts, accounting for 16.
    5% of the country's total installed power capacity, and the annual power generation capacity will be 1.
    34 trillion kWh, accounting for 16.
    1%
    of the total social electricity consumption。 Hydropower is currently one of the most economical clean and renewable energy, with stable power generation, strong peak regulation capacity, fast start-stop speed, high scheduling flexibility, can assume the heavy responsibility of peak regulation for new energy power generation, and play a role of "stabilizer" and "regulator" in the new power system with new energy as the mainstay
    .
    In addition to power generation, hydropower projects can also achieve flood control, shipping, ecology, comprehensive utilization of water resources and help rural revitalization and other multi-goal, multi-functional and multi-benefit
    .
    Further development of hydropower can solve the contradiction between resources, development and ecological protection, and promote the rapid economic and social development
    of areas rich in hydropower resources。

    China's hydropower technology can be developed to 687 million kilowatts, and the current development degree is only 57.
    1%.

    The degree of joint dispatch of cascade power stations in developed river basins is not high, and leading power stations with greater regulation capabilities in some river basins need to be developed, which restricts cascade power stations from exerting greater comprehensive benefits
    .
    China's stations for the construction of pumped storage power stations are rich in resources, but the proportion of installed capacity of pumped storage power stations that have been put into operation in the power system is low, and the development potential is huge
    .

    New energy sources such as wind power and solar energy have ushered in new opportunities for
    development.
    Driven by the goal of carbon peak carbon neutrality, the development of new energy such as wind power and solar energy has ushered in major opportunities, becoming the main force of electric energy increment, and will realize the transformation
    from "supplementary energy" to "main energy".
    In addition to the large-scale wind and photovoltaic resource base in the northwest region, China's offshore wind power resource endowment is good, the resource reserves are large, compared with onshore wind power and solar energy, the offshore wind power utilization hours are high, the output is more stable, and it is close to the electricity load center on the eastern coast, and the power consumption conditions are good, which is one of
    the renewable energy with the most development potential。 The results of the survey of wind energy resources show that the development potential of offshore wind power with a water depth of 5-50 meters and a height of 70 meters in China can reach 500 million kilowatts

    New energy has typical intermittent characteristics, and the output random fluctuation is strong
    .
    As wind power and photovoltaics enter the multiplication stage, China needs to accelerate the construction of a new power system with new energy as the mainstay, significantly improve the consumption and storage capacity of new energy, and realize large-scale development and construction of new energy and high-level consumption and utilization
    。 New energy power enterprises should promote the continuous progress of new energy technology, the continuous decline of costs, the continuous improvement of efficiency, and the continuous enhancement of competitiveness, fully get rid of the dependence of wind power and photovoltaic power generation on financial subsidies, and achieve market-oriented development
    at parity or even low prices.
