Which is better, wind power or photovoltaic power?
Have you ever seen windmills or solar panels while passing by the outskirts? Have you ever questioned which one is better? This is actually a comparison between wind power generation and photovoltaic power generation.
At the beginning, electricity generation on grasslands relied on wind to complete daily household lighting. With the continuous development of technology, people gradually discovered the drawbacks of wind power generation. Firstly, wind power generation converts wind energy into electricity, which is an uncontrollable factor. In windless environments, there is no electricity at all. Secondly, the noise generated by wind turbines during rotation is very loud, and the surrounding neighbors are suffering greatly.
So in comparison, photovoltaic power generation has become the choice of more people.
Firstly, the process of photovoltaic power generation is simpler than wind power generation. There are no mechanical rotating parts, no friction or sound, no fuel consumption, no emissions of any substances including greenhouse gases, no noise, and no pollution. Therefore, compared with new power generation technologies such as wind power, biomass power, and nuclear power, photovoltaic power generation is a renewable energy generation technology with the most sustainable development ideal characteristics (the richest resources and the cleanest power generation process). In addition, wind turbines for power generation also require frequent internal maintenance.
Secondly, photovoltaic panels can absorb energy as long as there is light, and the sun rises in the east and sets in the west every day. Even at night or on rainy days with bad weather, photovoltaic panels can use the stored electricity. According to thermodynamic analysis, photovoltaic power generation has a high theoretical power generation efficiency, reaching over 80%, and has enormous potential for technological development.
Finally, solar energy resources for photovoltaic power generation are readily available, allowing for nearby power supply without the need to be built on mountaintops like wind power generation, thus avoiding energy loss caused by long-distance circuit line transportation.
