Explanation:2. Wind power
Wind power is the use of air flow through wind turbines to provide kinetic energy to turn electric generators for electricity. Wind power does not require any fossil fuel to produce energy as long as there is enough wind to turn turbines at just 15-20 rpm. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulphur dioxide—causing human health problems and economic damages. Wind turbines don't produce atmospheric emissions that cause acid rain, smog, or greenhouse gases. In fact, wind power does require an abundant amount of land. Our teammate had been to Japan in research for their development in wind power. In fact, a lot of Japanese farmers had actually installed a few wind turbines in close proximity of their farmlands. We were told that these wind turbines are capable of providing enough electricity for all the electric and automatic farming tools. This greatly benefits the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. By the same token, wind power plant owners make rent payments to the farmer or rancher for the use of the land, providing landowners with additional income. During our research, we found that 1 wind turbine can already power up 1219 homes. Since concrete jungles such as our home Hong Kong has a very limited land supply, wind turbines do not seem to be practical for development in Hong Kong.However,wind turbines can also be built in the sea.and produce more energy than the same area of so;ar panels. Therefore, it is more effective than solar energy, both in terms of materials and productivity.
Other than that, wind power does not require water to generate electricity. Unlike burning fossil fuels, which require heat to transform water to steam in order to rotate the turbines and wasting water (as seawater cannot be used for electricity generation due to the residues left behind) Research showed that wind power can save at least 174000 bathtubs of water every year. Additionally, wind turbines do not affect the natural landscape too much and are compact compared to other types of renewable energy(one wind turbine can replace 16000 solar panels, which is the size of 4 football pitches).
Another reason for choosing wind power over other forms of renewable energy is the low number of restrictions on where they can be built or used. Although Wind turbines require a lot of land in order to work properly, they can be built practically anywhere. Wind farms can be built on farmland while not affecting the agricultural activity in the area, with the benefit of an extra source of income for the farmers, as mentioned above. Wind farms can also be built in water( in the sea or lakes). The United Kingdom is very successful in making use of wind energy. It is also the world leader in offshore wind farms. We will take a look at why it was so successful in the uk.
In the Uk, onshore wind energy is the most cost-effective way of obtaining clean energy( by 2022, each kWh of electricity generated by wind will only cost 5.8p ( around 5.50 HKD)). The role of wind power in energy production is getting bigger and bigger and surpassed coal in 2016. Currently, Wind power provides power for about one sixth of the UK. It has already provided 7.25 million homes with clean energy, which is 9% of the power needs of the UK. combined with offshore wind farms, Wind power powers nearly 12 million homes in the UK.
According to a poll from the British government, over 70% of British citizens support the development of Wind power. As the costs of wind power continues to drop, Wind power may be the cheapest form of energy in the future.
