Photovoltaic energy and wind energy are currently recognized as new sources of clean energy with little impact on the environment.
However, even if it is claimed that it is clean energy strictly speaking, whether it is photovoltaic or wind energy, it will have a certain impact on the environment .
For example, photovoltaics will have the following impacts on the environment:
1. Installing photovoltaic panels will take up a lot of space.
2. During the production process of photovoltaic panels, trichlorosilane and silicon tetrachloride will be produced, which are substances that have an impact on the environment and human health.
For example, wind energy will also have an impact on the environment during the deployment process.
It is said that the large-scale deployment of wind energy will affect atmospheric circulation and causechanges in ambient temperature.
It is also said that the large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of precipitation areas.
Even if the above statement is accurate, the two new energy sources of photovoltaic power and wind power themselves have not yet achieved 100% impact on the environment. ...it will have some impact to some extent.
Of course, compared to traditional energy sources, photovoltaic and wind energy have very little impact on the environment and are sufficiently environmentally friendly. This is why these two new sources of energy and other new sources of energy have such advantages. extensive development.
Which is cheaper: wind power generation or photovoltaic power generation? Wind energyis low, wind power costs about 4-5 yuan per watt, and photovoltaic power costs about 7-8 yuan per watt. Low-light photovoltaic panels are cheaper. As photovoltaic power generation technology, especially photovoltaic panels, continues to mature, the application of photovoltaic power generation continues to expand. Photovoltaic power generation is also an emerging industry with good prospects.
Photovoltaic energy production equipment takes up less space and is also suitable for use in cities. Wind power generation equipment should be used in locations with stronger winds, and these locations should be away from large cities.

Advantages and disadvantages of photovoltaic power generation:
1 . energy productionphotovoltaic
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
①No risk of depletion
②Safe; and reliable, no noise, In addition to not emitting pollution, it is absolutely clean (no pollution);
③It is not limited by the geographical distribution of resources, and can take advantage of roofs of buildings for example; , areas without electricity and areas with complex terrain;
④Can generate electricity and provide electricity on site without consuming fuel or erecting transmission lines;
⑤High energy quality;
⑥Easy for users to accept emotionally;
⑦ The construction period is short and the time spent on obtaining energy is short.
2. Disadvantages of photovoltaic power generation
① The power distribution density ofthe irradiation is small, that is, it occupies a huge area
② The energy obtained is the same as that of the four seasons, day and night, and it is related to weather conditions such as cloudy and sunny weather.
③ At present, compared with thermal power generation, the cost of electricity generation is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
