Photovoltaic energy production should be safer than wind energy. The only uncertainty factor of photovoltaics is bad weather, but its certainty is that day and night changes are certain. This certainty coincides with the peak hours of human production activities. This is what large electricity networks appreciate, and it is also incomparable with wind power. power. The biggest disadvantage of wind energy is uncertainty, because the presence or absence of wind energy as well as the magnitude of wind energy is not determined by human will.
In addition, the cost of photovoltaic power generation will decrease with technological progress, while the cost reduction of wind power is not expected to be too great. Photovoltaic energy production should therefore be more promising than wind energy.
Which is the least harmful to the environment,photovoltaic power or wind power?
Which is cheaper, wind power or photovoltaic power generation? Wind power is 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 major citiess.

The advantages and disadvantages Photovoltaic energy production:
1. Advantages of photovoltaic power generation
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
< p>①None risk of burnout;② Safe and reliable, no noise, no polluting emissions, absolutely clean (no pollution
③ Not limited by the geographical distribution of resources); the advantages of building roofs can be used; 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;
< p>⑤High energy quality;⑥It is easy for users to accept it emotionallyment;
⑦The construction period is short and the time required to obtain energy is short.
2. Disadvantages of photovoltaic power generation
① The energy distribution density of irradiation is low, 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.
Photovoltaics 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 a clean energy strictly speaking, whether it is photovoltaic energyWhether wind-powered or wind-powered, 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. Photovoltaic panels will produce trichlorosilane and silicon tetrachloride during the production process, which are harmful to the environment, substances that impact human health.
For example, wind energy will also have an impact on the environment during the deployment process.
It is said that large-scale deployment of wind power will affect atmospheric circulation and cause changes 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 though the above statement is exacte, the two new energy sources of photovoltaic energy and wind energy themselves have not yet achieved 100% environmental impact. ...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.
