Every year, wind turbines produce about 434 billion kilowatts (kWh) of electricity a year. Just 26 kWh of energy can power an entire home for a day. Wind is the third largest source of electricity in the United States with 40 of the 50 states having at least one wind farm. Contact online >>
Every year, wind turbines produce about 434 billion kilowatts (kWh) of electricity a year. Just 26 kWh of energy can power an entire home for a day. Wind is the third largest source of electricity in the United States with 40 of the 50 states having at least one wind farm.
That explains why wind turbine service technician is one of the fastest-growing jobs in the United States. The U.S. Bureau of Labor Statistics (BLS) reports that between 2022 and 2032, the job outlook for these positions is projected to grow 45%.63
Depending on size, location and model, wind turbines all have different energy outputs. There are two basic types of wind turbines: the horizontal-axis turbine (HAWT) and the vertical-axis turbine (VAWT). Both are ideal for different purposes and have different models to make them more efficient.
VAWTs are a special type of wind turbine that can use wind from different directions. Because its main rotor shaft is pointed vertically, a VAWT doesn''t need to be pointed toward the wind to work. This type of turbine is perfect for areas that don''t have stable wind power.
There are two types of VAWTs: the Savonius vertical-axis wind turbine and the Darrieus vertical-axis wind turbine. The Savonius model is typically smaller than other wind turbines and is optimal for areas with low wind speeds. It can produce about 172 kWh of energy per day.
The Darrieus model is quieter than other turbines and is ideal for areas where noise is a concern. It can produce about 230 to 11,300 kWh of energy per day depending on the size. Darrieus VAWTs are also known as "eggbeater" turbines.
HAWTs are currently the most efficient type of wind turbine. Even if they do rely on the direction of the wind to produce electricity, their rotors point them toward the right direction. Types of HAWTs are determined by the number of blades they have. There is the single-bladed, two-bladed, three-bladed and multi-bladed.
Overall, HAWTs are the more common type of turbine and are also a lot larger than VAWTs. How much electricity can a single HAWT wind turbine generate in a day? About 26.1 megawatts (MW). One MW is 1,000 kWh, so HAWTs can provide a lot more electricity!
The most efficient setting for a functioning wind turbine is an area that has regular wind flow. Strong winds can produce more energy. However, if the winds are too strong and not constant, the wind turbine will not produce as much energy. The three main factors that affect the energy production of a wind turbine are the wind speed, air density and size of the blades.
A wind farm, also known as a wind power station, is an area where a lot of large wind turbines are grouped together. On average, there are about 50 wind turbines per farm, and typically, one of these turbines can produce 6 million kWh per year. That would mean that one wind farm could produce 300,000 MW a year. That is enough electricity to power millions of homes.
Size is a big factor when it comes to the amount of energy a wind turbine can produce. No matter what type of turbine, even in an optimal location, a small wind turbine can realistically only produce so much power every hour. Harvesting wind power has a lot to do with the length of the blades. The taller the tower, the longer the blades can be and the more electricity can be produced.
Wind turbine technicians, also known as wind techs, service and maintain wind turbines. This type of job is very hands-on, gives opportunities for traveling to job sites and is generally done outdoors.
According to the Bureau of Labor Statistics (BLS), the average salary for wind turbine technicians in the United States was $57,320 in May 2022.61 Keep in mind that salary depends on several factors, including experience, employer, demand and cost of living in the area.

How much energy a wind turbine produces can vary depending on a range of factors. The output of a turbine can vary depending on its size, placement and average wind speed over time. This article explores the topic of wind turbine capacity and how much power they can generate in different scenarios.
Let’s start by exploring how much energy different types of wind turbines can produce. The maximum amount of power will vary depending on various conditions such as how fast the wind is blowing.
Large wind turbines are used by utility companies for renewable power production. They are often found in clusters known as wind farms. These can be onshore or offshore but generally speaking, offshore locations have higher wind speeds. Wind projects of this scale result in the largest amount of energy production.
The world’s largest wind turbine is the Haliade-X 12 MW offshore turbine from General Electric (GE). This has the potential to generate 67 GWh of wind power each year – enough to power around 16,000 homes. The company estimates that using the Haliade-X in a 750 MW wind farm could power up to 1 million homes. You can take a look at GE’s promotional video below.
The closest competitor to the Haliade-X is the V174-9.5 MW turbine from MHI Vestas Offshore Wind. This turbine can power around 9,000 homes and is a variant of their previous record-breaking turbine, the V164-9.5MW.
The V174-9.5 MW turbine features several enhancements to boost power output including a larger rotor size. The company has announced a more powerful turbine, the V164-10.0 MW which is available for installation from 2021.
Residential turbines are an option for those looking to tap into the power of the wind. Such turbines tend to start from around 1 kW, going up to 10 kW. Most homes are better off with at least 2 kW rated power output, depending on their power requirements.
A mid-ranged domestic turbine of 5 kW can provide around 8,000 kWh to 9,000 kWh of energy per year under the right conditions. Smaller turbines of around 2 kW can have an electricity generation of up to 3,000 kWh. Larger residential turbines have the potential to reach 15,000 kWh.
Some domestic turbines can reach over 15 kW however these tend to be much larger than those up to 10 kW. As a result, they are more suited to farms and large private estates.
The above data shows the estimated annual energy capacity in kWh at a wind speed of 5m/s. This will, of course, vary depending on the type of wind turbine, where you live and many other environmental factors. To get accurate figures, you should always consult a qualified domestic wind turbine installer who can carry out a feasibility assessment for your area.
Portable wind turbines are an option for those who require power on the move. These are popular amongst campers and recreational vehicle owners and can produce up to 600 W of wind energy.
The main producers of wind energy are China, the United States, and Germany. This is followed by India, Spain, and the United Kingdom, all of which have respectable capacities.
In 2018, China had a wind power capacity of 184,696 MW. Compare this to the USA who had a capacity of 94,295 MW and you will notice how China is well ahead in the rankings.
