把溫室效應這種全球規模的現象,硬套到風力發電機可能造成的小面積影響 信口開河也不是這樣……

Many US and European wind turbines are old, inefficient and installed close to human habitation. Also many didn't get maintained regulary, broke down and left to deteriorate. Once they fail the required return margin they would be decommissioned. China's wind farms are newish and usually installed in remote areas in large numbers with reasonable capacity say in excess of 2MW each. They are new and adequately maintained and systematically managed.

@@硬核科普知识 Yes. I have spent all life working on power generation mainly on large thermal power plants of all types from disel, gas, crude oil, coal and nuclear. I have not personally participated in wind and solar generation myself but am conversant with the technology. You spent a lot of the footage explaining the inner working, selection of GRP and design of a wind turbine. This is not relevant to the title of your video. My comments are based on what I have seen on the decommissioning of wind turbines in the west. Also wind energy is an enemy of the big gas and oil companies in US so any disatifaction, like malfunctions, outages, noises, environmental impacts and failure of the blades could be politicised and used to remove the wind turbines. China manages to install wind turbines in uninhabited area and systematically manage them so the growth of this sector is still bright. You know a wind turbine is a mechanical system. As such it will eventually break down or becomes obsolete. China wind generation is still young and has not had the experience of disposing large amount of obsolete wind turbines yet. I believe the biggest of them has grown to 16 MW. There will be a limit on how it can be erected and maintain. Already most of the big wind turbines have to be installed offshore. Wind turbine does use up a lot of unpopulated land.

First of all, many people just looked at the front of my video and didn't see the back. Second, there are some problems in wind power generation. You don't understand the situation in China. Third, wind power generation, solar energy and hydropower are regarded as clean energy, and they are inexhaustible. China is now vigorously building wind power, which is built in a large area. It can be said that it is so large that you can't imagine. China's thermal power generation is now shrinking. I personally like mechanical knowledge. When you see my video, you should find this. At the same time, you should also like machinery.

Talking about thermal power plant. It is sad that public still take it a one of the major source contributes to air pollution. I might not right, but aside waste product by thermal power plant, there are actually more major pollution caused by the other industry. Expand your vision and look into thing with better understanding on bigger picture. Hungry for electricity, but didn't want to provide any good effort and yet still demand for even cheaper electricity. No matter how, still some more reject thermal electricity. This is sad that public education nowadays is pretty lagging behind and can't discuss thing fruitfully together with better knowledge exchange.
Total annual U.S. electricity generation from wind energy increased from about 6 billion kilowatthours (kWh) in 2000 to about 338 billion kWh in 2020. In 2020, wind turbines were the source of about 8.4% of total U.S. utility-scale electricity generation.Mar 17, 2021。(google) 你真的是美国人?
