- Clean energy: Energy sources that do not release pollutants.<\/li>
- Dirty energy: Energy sources such as fossil fuels that cause environmental damage.<\/li>
- Green Energy: Energy from natural sources such as wind, sunlight and water.<\/li>
- Renewable energy: Energy is generated from sources that are being replenished constantly.<\/li><\/ol>\n\n\n\n

<\/div>\n\n\n\nThe Blades on the Turbine Go Round and Round<\/strong><\/p>\n\n\n\n
Wind turbines are normally placed in open spaces to catch more wind.<\/em>
(Source: <\/em>Pexels.com<\/em><\/a>)<\/em><\/figcaption><\/figure><\/div>\n\n\n\nWind turbines are like the rainbow pinwheels from my childhood but 1000 times bigger and less colourful. When the wind blows through the turbine, causing its blades to spin, kinetic energy harnessed by the wind can then be converted to the electricity<\/strong> that we use3<\/sup><\/a>. Wind farms can be built both on land and at sea<\/strong> to catch the wind, normally in open spaces where the wind is not obstructed4<\/sup><\/a>.<\/p>\n\n\n\n
<\/div>\n\n\n\nIt\u2019s Not Easy Being Green<\/strong><\/p>\n\n\n\n
Is wind energy all that eco-friendly though? While it is renewable, does it harm the environment? <\/strong><\/p>\n\n\n\n
The truth is that wind farms aren\u2019t totally green as they still have a carbon footprint, can cause noise pollution and pose threats to animals.<\/strong><\/p>\n\n\n\n
Firstly, it\u2019s to be expected that wind farms have a carbon footprint since wind turbines don\u2019t occur naturally. Constructing, transporting and maintaining the turbines all generate greenhouse gases5<\/sup><\/a> \u2014 but still not as much as the use of fossil fuels! Using natural gas to power a 3-room HDB flat in Singapore produces 440 times<\/strong> the emissions produced if wind energy was used instead6<\/sup><\/a>, making wind energy still a better option than fossil fuels. <\/p>\n\n\n\n
<\/div>\n\n\n\nDo You Hear Something?<\/strong><\/p>\n\n\n\n
Did anyone do this as a kid? (Source: <\/em>Tenor<\/em><\/a>)<\/em><\/figcaption><\/figure><\/div>\n\n\n\n <\/p>\n\n\n\n
Have you noticed that fans make a sound when they spin? My ceiling fan makes this \u201cwhum\u201d noise and wind turbines are no exception as they produce a low pitched noise when the blades are spinning7<\/sup><\/a>. Some studies have shown that people living near wind turbines are affected by the sound and that it could cause negative health impacts such as insomnia and headaches8<\/sup><\/a>. However, another report by the Iowa Environment Council found no concrete proof that these problems were caused by the noise from wind turbines, and that some people may just be falsely attributing their symptoms to the wind turbines due to their disfavour towards wind farms9<\/sup><\/a>. To make your own judgement of how loud the sound is, click here<\/a> to see a decibel test comparing the noise levels of wind farms to other places!<\/p>\n\n\n\n
<\/div>\n\n\n\nWhat About The Animals?!<\/strong><\/p>\n\n\n\n
Unfortunately, land animals, marine animals and birds can all be affected by wind farms. Birds and bats can collide with the spinning blades and get hurt7<\/sup><\/a>, while noise pollution from the construction of offshore wind farms (wind farms out at sea) can interfere with the communication between marine mammals10<\/sup><\/a>. There is also a loss of habitat as wind farms are generally built in open spaces, which could cause some animals to avoid these areas11<\/sup><\/a>. In this case, switching to renewable energy does come at the cost of biodiversity loss, emphasising the need to balance these two priorities.<\/p>\n\n\n\n
<\/div>\n\n\n\nLet\u2019s Get Local<\/strong><\/p>\n\n\n\n
If wind energy is still cleaner, why are we still using natural gas in Singapore? <\/p>\n\n\n\n
Actually, did you know that Pulau Semakau has a working wind turbine<\/strong>12<\/sup><\/a>? It is part of a project where power grids are being built to increase our reliance on cleaner energy sources, which is in line with Singapore\u2019s goals for sustainable energy. <\/p>\n\n\n\n
However, mainland Singapore doesn\u2019t have the right conditions for wind farms13<\/sup><\/a>, so we still have to rely on natural gas for now. Despite this, there may be hope for wind farms in our neighbouring countries which we could collaborate on and tap into14<\/sup><\/a>. Sadly, the costs of wind energy projects compared to other energy sources like solar have caused progress to be slow15<\/sup><\/a>. In this case, wind energy may hence not always be the best alternative to dirty energy, particularly in Singapore, since the feasibility is low.<\/p>\n\n\n\n
I think that more research should be done on wind power, so as to reduce the negative impacts and costs, leading to a greener energy source. <\/p>\n\n\n\n
Now, I\u2019ve told you what wind energy has to offer, but what do you<\/em> think about it? Leave a comment below and share your thoughts on wind energy in Singapore!<\/p>\n\n\n\n
