Energy trends worldwide are witnessing a shift, and renewables are on the rise. According to the US Energy Information Administration, wind energy is the leading electricity production source among renewables, with a share of 10.2% in total energy production.
These statistics underscore the immense benefits of wind energy. It's not just clean, green, space-efficient, and cheap but also a beacon of hope for a sustainable future. However, it's important to acknowledge the challenges and limitations that come with it.
The article will comprehensively explain the pros and cons of wind energy and how you can benefit from it.
What Is Wind Energy?
Wind energy is the energy produced by converting the kinetic energy of wind into electrical energy. If you have ever seen a wind turbine, you probably already know something about wind energy.
A wind turbine consists of three fundamental parts including blades, generator, and wires. Blades capture wind's kinetic energy, generators convert it into electrical energy, and wires eventually supply the grid with the power produced.
When wind blows, its kinetic energy helps the blades of a wind turbine move. This motion runs a connected generator to produce electrical energy that is supplied to the grid.
It's important to note that wind energy is not a continuous power source. It depends on the wind. Simply, this means no wind, no energy. However, even the intermittent energy production of wind with a medium-sized turbine operating for around 100 hours can produce enough power to fulfill the electricity needs of a household for a month.
Pros And Cons Of Wind Energy - Comparison
The first windmill setup was built in 1888, and since then, it has been a reliable source of energy. With its manyfold benefits, like clean and cheap energy, it also has some cons. The table below is a brief head-to-head comparison of the associated pros and cons of wind energy.

Advantages Of Wind Energy
Wind energy can shape the future of global energy production due to its various benefits. Unlike fossil fuels, it does not produce toxic emissions. It is cheap, sustainable, and abundant. Below is a comprehensive discussion of the various benefits of wind energy.
Clean And Green Energy
Greenhouse gases emitted by fossil fuels have pushed climate change to a disastrous level. Wind energy can help change the scenario. Wind turbines' work completely relies on wind and does not release any toxic fumes.
Some pollution might be associated with manufacturing and installation, but that is insignificant compared to fossil fuels. Wind turbine's overall operation is completely carbon-free, so their produced energy is clean and green.
Renewable And Abundant Source Of Energy
Renewable energy sources are those that can be replenished and never run out, such as wind energy. Wind is a natural phenomenon, and its consumption does not mean we are consuming the available wind that will eventually end. So, it's a renewable and abundant source of energy.
Cost Effective
The average per kWh cost of wind energy is around ¢1 to ¢2 cents, which is very cost-effective compared to other renewable energies, especially fossil fuels.
Although the initial wind turbine installation involves hefty upfront costs, due to minimal operation and maintenance costs, it will be paid back soon.
Space Efficient
Unlike solar panels that require side-by-side installation, wind turbines cannot be installed in the same fashion. They need large gaps between them. However, as they don’t require any land acquisition, the space between them can be used for farming or any other purpose. This is why they are space-efficient solutions.
Job Creation
According to the US Office of Energy Efficiency & Renewable Energy, wind energy is estimated to produce 600000 new job opportunities by the end of 2050.
The trends of wind energy are on the rise. In the US only, its installation doubled between the period of 2010 to 2018 and around 30 million households are reliant on wind energy. This shift has spurred the job creation and made wind turbine technician the second most fast-growing job in the US.
Disadvantages Of Wind Energy
While wind energy offers scores of benefits, it also has some associated challenges and limitations. Here are their details.
No On Demand Energy Production
The most fundamental disadvantage associated with wind energy is its unpredictability. This means you will only have energy if enough wind speed is available to rotate the turbine blades.
This makes it not a primary power source to rely on. However, with the technological advances in power storage options, its future is bright to make it more reliable. Until then, additional resources like solar power or the use of fossil fuels are critical to meet the high power demands.
Negative Affect On Wildlife
Though wind energy does not emit any toxic gases, it may affect wildlife. Some estimates reveal that around 140000 to 500000 birds expire annually when they come in direct contact with wind turbines. Nonetheless, the figures are much lower regarding bird deaths resulting from building collisions.
However, in the case of wind turbines, careful installation in areas with low bird activity can curtail the risks.
Noise Pollution
Wind turbine’s continuous blades and generator noise could be a problem in residential areas. But the new models of wind turbines are almost noise-free. Further, careful planning of wind turbine farms with sufficient gaps can also be a reasonable solution to the issue.
Aesthetics
Some people find the high wind turbine installations unappealing to the overall look of the landscape. Further, the shadows of blades could also be disturbing. However, this disadvantage of wind energy is more related to personal preferences, as some people also find wind turbines to boost the aesthetics of a landscape.
Installation Limitations
Proper installation location is crucial to the working of wind turbines. This includes areas where sufficient wind blows, and the turbine installation cannot consume the gap space between them.
The perfect locations for wind turbines are often coastal areas, mountains, or far-flung countryside. So, installations in such areas require an overhaul of infrastructure that can be costly and may have worse effects on the natural ecosystem.
How Much Electricity Does A Wind Turbine Produce?
The energy produced by wind turbines is dependent on three primary factors. These include the size of the turbine, its type, and available wind speed. However, the new variable of wind turbines is rotators with more efficient aerodynamics that ultimately help them produce more power.
In the US, the average monthly energy production of Wind turbines is around 400000 kWh per turbine with an average operating efficiency of 33%. That means turbines convert only 33% of the available kinetic energy of wind.
Still, the electricity produced is enough to meet the power requirements of 450 US households, with an average monthly energy consumption of around 900 kWh
Is Wind Energy Cheap?
Yes! Wind energy is cheap for commercial installation compared to other renewables. Although its initial setup costs are relevantly high, the minimal operational and maintenance costs make it more affordable in the long run.
According to the American Wind Energy Association, the average per-kWh cost of wind energy is less than ¢5. This is much less than solar energy’s average cost of ¢20 to ¢30 per kWh.
Also, unlike solar farms, which can be built almost everywhere, wind turbines require specific locations with additional infrastructure that is only feasible in case of commercial setup and not suitable for residential purposes.
Is Wind Energy Cause Pollution?
No, wind energy is clean energy. It does not involve the burning of any fossil fuels, so it does not emit greenhouse gases. Although, there are some concerns over its manufacturing, impact on wildlife, and noise pollution.
As mentioned above, wind turbines kill many birds, and their continuous operational noise can be bothersome in residential installations. Overall, compared to other energy sources, wind turbines have negligible environmental impacts and cause negligible pollution.
What Clean Energy Is Available for Home Use?
Wind energy is clean, green, and also cost-effective in the long run. Still, even though it has various advantages, it is not suitable and recommended for residential purposes due to various reasons. These include
- Very high upfront cost
- Availability of Infrasture
- Location Compatibility
- Aesthetic preferences
So, what is the best clean energy source for home use? Of course, solar power. This renewable energy source is reliable and does not have any environmental implications. In some cases, like the products of BLUETTI, it's portable. Also, like wind energy, its installation cost is paid back in half of the lifespan of its setup.
