If you’ve been asking yourself “Why is wind energy good for the environment?” you may be wondering if it’s as simple as a few spinning blades atop a tower. In reality, however, wind power is a healthy alternative energy that does not negatively impact the environment. Wind turbines can be installed in backyards, towering over hills, and anywhere in between. The best part is that wind power is incredibly cost-effective, making it a viable alternative to solar and other energy sources.
Reduces air pollution
There are many benefits to using wind energy to generate electricity. According to the Environmental Protection Agency, wind energy displaces kilowatt hours from sources that release harmful chemicals into the air. In 2010, wind generation displaced more than 75,000 tons of sulfur dioxide and nearly 50,000 tons of nitrogen oxides, two of the most common air pollutants that contribute to acid rain and smog. By 2050, the total amount of carbon emissions emitted by wind generation could be reduced by nearly 400 billion metric tons.
As a result of wind energy’s many benefits, the use of this renewable resource contributes to reducing global warming. The report also states that current wind-generated power prevents the emission of global warming pollutants equivalent to 13 million cars each year. This in turn reduces the risk of respiratory illnesses and asthma attacks. According to the report, wind energy reduced 176,000 metric tons of smog-forming pollution last year, which is equivalent to taking off more than half of all passenger cars in the United States.
Reduces climate impacts
The use of renewable energy for electricity production has a large number of advantages, including a reduction in emissions of carbon dioxide (CO2). The impact of CO2 on the global climate is proportional to the squared deviation of local temperature from pre-industrial mean. A small amount of wind power can reduce the climatic impacts of CO2-induced warming. Wind energy can also reduce low-latitude warming. The reduction in carbon dioxide emissions due to wind power is significant and helps to plan for a world without coal.
Although many studies have shown that wind power is less damaging to the climate than fossil fuels, the results of this study are ambiguous. However, they have found that increasing the drag coefficient can reduce atmospheric efficiency and alter climate. Additionally, turbine-generated turbulence is known to increase turbulent momentum transport and induce additional drag on the ground downstream of turbines. These factors are often ignored in climate impact calculations. This study shows that a small increase in wind energy production is beneficial for climate change mitigation.
A more aggressive set of noise reduction requirements for offshore wind projects is needed to ensure a lower impact on marine life. In Germany, projects must meet strict noise reduction standards or risk significant noise damage. Other countries have similarly stringent requirements, including the Netherlands, Belgium, and Denmark. And if the U.S. doesn’t lead the way, it should, at least. The goal should be to minimize the noise footprint of wind energy projects throughout their lifespan. Not only will reducing noise benefit marine wildlife, but it will also benefit the ecosystem as a whole.
Wind energy converters must be designed to reduce noise pollution. Noise is generated by rotor blades and cogwheels in wind turbines, which produce vibrations in the gearbox and relay them to the tower. Wind turbines emit vibrations throughout a wide area, so residents hear humming noise. If the wind speeds are high, the noise is magnified. Some wind turbines have anti-noise devices to prevent excessive noise.
Reduces aesthetic pollution
Despite the fact that wind farms are a great sustainable source of energy, their presence in the landscape and on the seascape is often met with opposition, primarily because of their presumed ‘eyesore’ effect. The purpose of this chapter is to assess various arguments aimed at reducing wind farm aesthetic pollution, and to evaluate which one is most promising. To succeed in this endeavour, any argument must be embedded within a larger aesthetics of sustainability and a thick sense of aesthetics.
Aesthetics are an important consideration, as the presence of wind turbines may be perceived as an eye sore or graceful sculpture. It is important to note that these considerations vary between locations and are often in conflict with protection of historic sites. On the other hand, wind farms are less likely to be perceived as an aesthetic polluter in industrialized areas than in rural, suburban, or urban settings. However, aesthetics are subjective. While some people find wind farms pleasing, others consider them symbols of local prosperity and energy independence. While others claim that wind farms will negatively impact tourism and aesthetics, some have even become tourist attractions.
Reduces CO2 emissions
The reduction of CO2 emissions from wind energy has multiple benefits. The technology can reduce the pollution of the atmosphere, and it can help mitigate the impacts of global warming. A comparison of the CO2 emissions of wind and other energy technologies shows the societal benefits of wind energy. Carbon dioxide, sulfur dioxide, and nitrogen oxide are greenhouse gases that are linked to global warming. By reducing these emissions, the technology can reduce CO2 emissions by over 80 percent.
The cost of wind and solar energy production is also a consideration. Solar and wind plants operate at less than 90 percent of their capacity. The higher cost of solar and wind plants makes them less valuable than other sources of energy. In fact, wind and solar energy have higher CO2 emissions than most other energy sources. Therefore, it makes economic sense to quickly adopt these renewable energy technologies. It is also a good option for countries that have high demand for electricity.
