Recently I read an article where Denmark generated 140% of it’s electricity demand. If you must know, Denmark usually produced almost 40% of it’s electricity demand. But this time not only it managed to produce more but also managed to export it to the countries like Germany, Sweden & Norway. That got me wanting to know more how Wind Power works and which countries are really efficient in using it wisely.
Of course, we all have studied about solar or wind power during our school days but let’s take a quick review of it’s pros and cons of Wind power.
Pros:
1) Renewable energy: Well, as windy as it could be your city, the better it is. As you could see from the image too that the more the turbine turns and it generates more electricity for us to use.
2) Clean energy: Well, we are not burning any fossil fuels here so it’s a top pro for me to consider wind power any day.
Cons:
1) Wind reliability: It could only work if your city or surrounding area is windy enough to produce this clean energy.
2) Expensive: Even though you can reap benefits over a long long time but the initial investment is indeed on the higher side, not to mention you need bigger farms to install it.
However, that being said Wind Power is still the cheapest energy considering Onshore wind is cheaper than coal, gas or nuclear energy when the costs of ‘external’ factors like air quality, human toxicity and climate change are taken into account.
The report says that for every megawatt hour (MW/h) of electricity generated, onshore wind costs roughly €105 (£83) per MW/h, compared to gas and coal which can cost up to around €164 and €233 per MW/h, respectively.
Another interesting fact to see is the USA,China and India are among top wind energy producers but highest polluters too.
