The production of photovoltaic solar energy has no impact on the environment. Photovoltaic panels can be installed on hillsides and lakes to reduce the use of available land. Photovoltaic solar energy production has no impact. on the environment, it occupies a large area and is not suitable for the use of photovoltaic panels to produce electricity in some places where available land is scarce and where the days are many and cloudy and rainy. Solar photovoltaic power generation does not pollute the environment, but it occupies a large area and can only produce electricity during the day. Electricity at night must be stored during the day, so most electricity is produced by wind power. Overheating photovoltaic panels will release certain elements, around 270 degrees, harmful to certain plants. PTherefore, the farmland should be about 500 meters away from the photovoltaic panels, and the photovoltaic panels located on the hillside will not harm the crops down the mountain at all.
Which is less harmful to the environment, photovoltaic or wind energy?
Wind energy and photovoltaic energy have seasonality and obvious volatility, and the increase in the proportion of wind and solar power generation will affect the stability of the electric power system.
Wind power generation relies primarily on wind energy, a natural energy source. Since wind speed in different regions is closely linked to climate change, wind energy supply also exhibits significant seasonality. For example, during active monsoon periods like winter or spring, the available wind resources will behave more abundant; while in summer or other dry and less rainy environments, factors such as sandstorms can affect the availability of wind resources.
At the same time, some specific geographic locations (such as mountains) also have certain wind stability requirements. This means that at different times electricity production will increase and decrease. Although modern technology can smooth out these fluctuations by storing excess electricity, there are still some technical challenges and limitations. ?
Solar photovoltaic (PV) systems, on the other hand, work by converting light into electricity. However, the intensity of sunlight also changes depending on weather conditions, including cloud cover, daylight hours, and intensity of UV radiation. This will affect the efficiency of photoelectric conversion, afthus further affecting the stability of the output power.
The principle of wind energy production
The devices required for wind energy production are called wind turbines. This type of wind turbine can be roughly divided into three parts: the wind wheel (including the tail rudder), the generator, and the tower.
The wind wheel is an important element that converts the kinetic energy of the wind into mechanical energy. It is made up of several blades. When the wind blows toward the blades, an aerodynamic force is generated on the blades to rotate the wind wheel. The blade material requires high strength and light weight and is often made of fiberglass or other composite materials.
The iron tower is the structure that supports the wind wheel, rudder and generator. It is generally built relatively high in order to obtain greater wind force.nter and more uniform and to have sufficient force. The height of the tower depends on the impact of ground obstacles on wind speed and the diameter of the wind wheel. It is generally between 6 and 20 meters.
The function of the generator is to convert the constant speed obtained from the wind wheel into an increase in speed. It is transmitted to the power generation mechanism to work uniformly, thereby converting mechanical energy into electrical energy .
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 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. Installation of photovoltaic panelss 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 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 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. ...this will have some impact onns to a certain 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 energy sources and other new energy sources have such advantages. extensive development.
