Is solar power generation better or wind power generation more environmentally friendly?

They are currently the most environmentally friendly power generation methods in the world.

Relatively speaking, wind power is even more superior.

Solar power generation (photovoltaic power generation) requires a large amount of land. An installed capacity of 10,000 kilowatts requires 350 acres of land (1 acres, 667 square meters), and it is densely arranged, so the land cannot be cultivated.

A wind power unit of 2,000 kilowatts only occupies 4*4M, or 16 square meters. Planting, grazing, etc. can still be done around the wind turbine.

Which one is less harmful to the environment, photovoltaic or wind power?

Photovoltaic is better,Although both belong to the new energy sector, the performance of photovoltaic in the stock market But it is far better than wind power. The market is very enthusiastic about photovoltaics, but not very interested in wind power. This is caused by many reasons. The main reason is that the future prospects of photovoltaics are better, but investment is always a matter of odds, that is, in Balance between risks and benefits.

The actual performance of photovoltaic and wind power in 2020 is similar, and the growth expectations for 2021, except for Follett's high point, are similar to wind power and photovoltaic. Photovoltaic has no obvious advantage over wind power. However, the share price increase in the photovoltaic sector was significantly greater, with Sungrow reaching an astonishing more than 7 times, and Longi also reaching 4.8 times. The stock price reflects that the capital market is more optimistic about photovoltaics, implying its views on the future growth prospects of related companies and its industry status, but it also implies the optimism of Mr. Market.

The current valuations of leading companies are all at historical highs, LONGi 80%, Sungrow, Flat, Mingyang Intelligent, Sun and Moon are all higher than 90%, Dongfang Cable 20%, Taisheng Wind Energy 5% , the latter two are the lowest. Generally speaking, the share price of the photovoltaic sector has increased significantly. Regardless of whether it is measured by dynamic price-to-earnings ratio, TTM, historical percentile, or PEG, the current valuation of photovoltaic is higher than that of wind power, but the performance and future performance in 2020 are actually similar to that of wind power.

Both photovoltaics and wind power are currently recognized as new clean energy sources that have little impact on the environment.

However, although it is claimed to be clean energy, strictly speaking, whether it is photovoltaic or wind power, it will have a certain impact on the environment.

For example, photovoltaics will have the following impacts on the environment:

1. The layout of 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 power 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 large-scale deployment of wind power will affect the circulation of water vapor in the atmosphere and affect the distribution of rainfall zones.

Leaving aside whether the above statement is accurate, the two new energy sources of photovoltaic and wind power themselves have not yet achieved 100% no impact on the environment. ...it will have some impact to some extent.

Of course, compared with traditional energy sources, photovoltaic and wind power have very little impact on the environment and are environmentally friendly enough. This is why these two new energy sources and other new energy sources have achieved such widespread development.
