Why is new energy (wind power, photovoltaic power generation) more expensive than coal power and hyd

I think it is: the one-time investment is too high, the wind turbine and its supporting equipment are too expensive, and the relevant domestic technical level is not yet mature, and various faults cannot be fundamentally solved. These make it difficult for investors to make decisions. It is also to support new energy power generation, which not only supports new energy, but also supports domestic production

Hydropower, wind power and photovoltaics are the main forms of current renewable energy

Affect the stability of the power system.

Wind power and photovoltaic power generation are representatives of renewable energy. The power generation is affected by weather conditions and has a certain degree of randomness and unpredictability. This makes the power system face some challenges when integrating wind power and photovoltaic power generation on a large scale. The volatility of new energy power generation causes fluctuations in grid frequency and voltage, affecting the stable operation of the grid. Large-scale integration of wind power and photovoltaic power generation will increase the uncertainty of the power grid. The integration of new energy power generation also requires solving technical challenges in grid stability and reliability.

Mature and slow.

Hydropower, wind power and photovoltaics are the main forms of current renewable energy. Among them, hydropower has been developed for a long time and the technology is relatively mature. Hydropower accounts for 50% of the total renewable energy power generation in Asia. However, due to the declining economics of site selection and increasingly prominent environmental and social issues, the development of hydropower may become slow in the future.
