Different nuclear power reactor types have different efficiencies. Let’s give a few examples (all are theoretical values):
AP1000 has a thermal power of 3400MW, an electrical power of 1250MW, and an efficiency of 36.8%
The thermal power of China's experimental fast reactor is 65.5MW, the electric power is 25MW, and the efficiency is 38.2%
High-temperature gas-cooled reactor is said to have an efficiency of 47%
The maximum thermal power plant is about 40-42% , generally more efficient than nuclear power.
Photovoltaic power generation efficiency: monocrystalline silicon 19%~21%, polycrystalline silicon: 16~17%.
Let’s not talk about the efficiency of hydropower and wind power. They directly convert mechanical energy into electrical energy.
Both wind power and photovoltaic power generation have the common advantages of being clean, renewable, and never exhausted. Wind power generation has more obvious advantages than photovoltaic power generation. Why do you say this? Mainly based on the following two points:
1. The cleanliness of photovoltaic power generation is relative, because the production of solar panels has the characteristics of high pollution and high energy consumption, and the manufacturing process is not environmentally friendly; while the cleanliness of wind power generation Cleanliness is absolute, which has obvious advantages over photovoltaic power generation!
2. After all, the energy distribution density of photovoltaic irradiation is small. To generate a large amount of electric energy, it takes up a huge area. Therefore, solar power stations generally occupy a relatively large area. A 1GW photovoltaic power station requires an area of 300-400 square meters. acres, so photovoltaic power stations are generally built in remote areas with vast land and sparsely populated land and barren land (it is impossible to build photovoltaic power stations on farmland in densely populated areas). Wind energy power generation facilities occupy a small area and have little impact on normal farming of farmland. Especially offshore wind power does not need to occupy land!
