Wind power and future

        Have you ever felt that summer is hotter today than it was when you were a child? With the continuous development of the world economy and the increase of human energy demand, the problems caused by global warming have emerged. The article questioned whether the large-scale deployment of wind power stations in the United States would solve the climate problem. In my opinion, wind power is a very useful initiative to change the modern energy structure system. I agree with the promotion of wind power stations.

        Compared with traditional power generation, wind power generation is significantly cleaner and more environmentally friendly. Global warming is a worldwide climate crisis. When people use fossil fuels, such as oil and coal, they produce a lot of greenhouse gases. These greenhouse gases cause the earth to heat up, the greenhouse effect. Global warming will redistribute global precipitation, melting glaciers and permafrost and raising sea levels, which will not only endanger the balance of natural ecosystem, but also threaten the survival of human beings. That’s why we have to eliminate fossil fuels. We don’t want a grey future.” The direct climate impacts of wind power are instant, while the benefits accumulate slowly,” says Keith. “If your perspective is the next 10 years, wind power actually has — in some respects — more climate impact than coal or gas. If your perspective is the next thousand years, then wind power is enormously cleaner than coal or gas.” 2016 was the warmest year on record, global average temperature 1.1 ℃ higher than before the first industrial revolution. I remember opponents discussing the harm of wind power to flying animals. If they knew how many species this degree could kill, they might not be opposed to sustainable energy. The Tyndall Centre for Climate Change Research has studied the changes of over 80,000 species under global warming. They argue that if global warming is unchecked, about half of all living things will cease to exist. As we all know, there are far more than 80,000 species in the world. No one can predict how many lives will be harmed by global warming, and all will pay the price for bringing the ecosystem to ruin.

        Winds are limitless, and people can get them in most parts of the world. This means there will be no regional or quantitative limits on power resources. This means economic improvements from energy production can also be received in areas without fossil fuel minerals. The government can deliberately use it to change the economic situation in some poor areas. This makes some areas more habitable for humans.

        This can also prevent some natural disasters caused by over-exploitation of minerals. The over exploitation of minerals has had many negative effects. Land subsidence is one of them. Land subsidence occurs in many countries (such as the United States, China, Turkey). Under the influence of human engineering economic activities, it is a local downward movement caused by the consolidation and compression of the loose underground stratum, which leads to the reduction of the height of the crust surface. If land subsidence occurs in urban areas, it may cause significant economic damage and casualties. If it happens in rural areas, that land will be difficult to grow crops.

                                               

        This is the photograph of the Winter Park, Florida sinkhole that opened in May 1981. This picture reminds me of the craters on the moon. If this ground subsidence continues, will the earth be as rugged as the moon. If we change the way we generate electricity from conventional sources to wind, that could be changed.

        Despite the many benefits of wind power, there are many opponents who argue that wind power poses some practical problems. Wind power, they argue, could bring down the old energy chain. This will result in massive job losses and losses of existing fixed assets. This eventually led to an economic crisis. “In transportation, more than 2.4 million men and women would be put out of work. Over 800,000 people working to produce oil and natural gas would lose their jobs,” according to EID’s Steve Everley. “Nearly 90,000 jobs connected to coal mining would be wiped out. All told, more than 3.8 million jobs would be lost, far more than the nearly 2.6 million long-term jobs that Jacobson has estimated would be created.” I disagree with this argument that wind power causes unemployment. In my opinion, wind power can liberate 3.8 million workers. As with previous technological revolutions, we will be able to do more with fewer people. The rest can go on to other jobs or enjoy the social benefits of productivity. We can imagine what the world would be like today if people gave up their factories to keep the jobs of the handicrafts men after the steam engine was improved. That’s why I don’t think you can use unemployment to hold back productivity growth.

        In conclusion, wind power is an environmentally friendly, flexible and affordable means of energy access. Wind power has shown enough advantages for the traditional power generation industry. I quite agree with the promotion of wind power, and I also want to see a better earth.
