Renewable energy can be recycled in nature, including solar energy, hydropower, wind energy, biomass energy, wave energy, tidal energy, ocean temperature difference energy, geothermal energy and so on. It is an inexhaustible and inexhaustible energy, which can be regenerated automatically without human participation. It is an energy relative to the inexhaustible and inexhaustible non renewable energy.
The consumption capacity of renewable energy system needs to be improved, and the utilization efficiency needs to be improved, mainly due to the following reasons: Based on the reverse distribution of China's resource endowment and load center, the matching between resources and load is relatively poor, which is difficult to be consumed in some areas; China's economy has entered the new normal, the power demand has slowed down, and the installed capacity is relatively surplus; In the "Three North" area, the peak load power supply in the power supply structure is relatively small. Auxiliary service policies are not in place or poorly implemented; The development and construction of renewable energy is fast, and the planning and construction of supporting power grids lags behind. The transmission capacity of power channels needs to be improved.
The technical level needs to be improved, and the cost should be reduced through further technological progress and industrial upgrading. For example, the problems of environmental protection and immigration in hydropower construction increase the difficulty of development, resulting in higher cost;
How to effectively use the core technologies such as offshore wind power, wind power equipment manufacturing, micro site selection, offshore wind power design and construction; Solar energy efficient crystalline silicon, thin film industry, harmless treatment and thermal power generation integration technology to further improve the conversion rate and realize affordable access to the Internet; Key technologies and industrial levels such as biomass natural gas integration, aviation fuel and green bio refining need to be improved; The development of ocean energy and geothermal energy has not yet reached the mature application stage.
In the initial stage of renewable energy development, countries need to encourage, support and support policies. The source of the national renewable energy development fund is single, it is difficult to levy additional electricity price, the subsidy of funds is delayed, and some power generation enterprises of wind power and photovoltaic have problems such as capital turnover difficulties and losses.
