I think this is the case: the one-time investment is too high, the wind turbine and its supporting equipment are too expensive, and the corresponding national technical level is not yet mature, and various defects cannot not be fundamentally resolved. It is difficult for investors to make decisions. It is also about supporting the production of new energy. This is not only about supporting new energy, but also supporting domestic production.
Which photovoltaic or wind energy is less harmful to the environment?
From a cost accounting point of view, this energy is said to be very cheap compared to thermal, hydroelectric and wind energy. First of all, thermal power, water power and wind power should be selected in areas that do not affect social activities and are subject to geographical restrictions, so that a long reelectric bucket should be built while there is one. suitable free space, and can even be installed on the roof of a building and connected to the network. Extremely practical and inexpensive. Secondly, compared with thermal power, hydropower, nuclear power and other power generation equipment, solar photovoltaic power generation equipment is very simple, and its cost is also much lower considering factors such as difficulty and construction period. Additionally, solar photovoltaic power generation equipment is relatively simple to maintain, so even if there is a problem, it is a local problem. There is no need to stop production for maintenance, and the operating cost is also very low. Therefore, for large-scale power generation equipment projects, solar photovoltaic power generation equipment is not expensive. If heis a domestic distributed power generation equipment, it should be considered from the point of view of cost recovery. Generally speaking, the cost can be recovered in 5 to 7 years and the service life is more than 30 years. an investment is a choice with an ideal rate of return.
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. 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 substanceswhich 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. ...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 rerespectful of the environment. This is why these two new sources of energy and other new sources of energy have such advantages. extensive development.
