Why Are Wind Turbines So Promising as a Technology?
Firstly, the technology is so effective, because, unlike solar panels, wind turbines work at night as well as during the day. Sure, there are windless days, but they barely happen, and even tiny gusts of wind can power these large structures.
Secondly, these large “fans” are relatively cost-effective. While the cost of raising a huge structure might be high, they generate much more electricity than solar panels. In fact, a single wind turbine can generate the same amount of electricity as seven football fields of solar panels. This means wind power has a much higher energy density. Wind turbines can convert around 50-60% of wind energy into electricity, while solar panels typically convert only 18-22% of solar energy into electricity. The Sun gives us a lot of energy, but we can’t really efficiently convert it into electricity, yet.
Of course, another promising aspect is the obvious one. By generating electricity from wind, we lessen our dependence on fossil fuels, which are finite resources with geopolitical and environmental complications. This fosters energy independence and security, while also reducing our contribution to global warming.
You can’t forget about all the economic benefits of a whole other industry popping up. Wind farms create jobs in manufacturing, construction, and maintenance. Additionally, landowners who lease land for wind turbines often receive payments, bringing economic benefits to rural communities.
Lastly, wind turbines have a relatively small footprint on land. They can coexist with agriculture and grazing, and the land beneath them can still be used for other purposes.
