As a renewable energy expert with a focus on wind energy, I am delighted to provide an in-depth analysis of the question at hand: "How many houses does a wind turbine power?" This question is not just about numbers; it's a gateway to understanding the impact of renewable energy on our daily lives and the environment.
Wind turbines are marvels of modern engineering, designed to harness the power of the wind and convert it into electricity. The amount of electricity a single wind turbine can produce depends on several factors, including the turbine's size, the wind speed at the site, and the turbine's capacity factor.
Let's start with the size of the turbine. The average size of a wind turbine in commercial use today is around 2-3 megawatts (MW). However, there are smaller turbines for residential use and larger ones for utility-scale projects. The 1.5-MW turbine mentioned in the reference is a good example of a medium-sized turbine that can be found in many wind farms.
The capacity factor is a crucial metric that represents the actual output of the turbine compared to its potential output if it were running at full capacity all the time. The capacity factor for wind turbines can vary significantly based on the location and the consistency of the wind. The reference provides a capacity factor of 26.9% for the 1.5-MW turbine, which is a realistic figure for many wind farms.
Now, let's consider the intermittency of wind power. Unlike traditional power plants that can operate continuously, wind turbines are subject to the variability of the wind. As the reference states, a wind turbine operates at or above its annual average rate only 40% of the time. This intermittency is an important consideration when calculating the number of households a turbine can power.
To calculate the number of households a 1.5-MW turbine can power, we need to consider the annual energy consumption of an average household. In the United States, the average household consumes about 877 kWh per month, which translates to approximately 10,524 kWh per year.
Given the capacity factor and the annual energy consumption of a household, we can estimate the number of households a 1.5-MW turbine can power. Using the reference's figure, a 1.5-MW turbine with a 26.9% capacity factor would produce:
\[ 1.5 \, \text{MW} \times 24 \, \text{hours/day} \times 365 \, \text{days/year} \times 0.269 \, (\text{capacity factor}) = 5,110,600 \, \text{kWh/year} \]
Dividing this by the annual consumption of a household:
\[ \frac{5,110,600 \, \text{kWh/year}}{10,524 \, \text{kWh/household/year}} \approx 486 \, \text{households} \]
This calculation suggests that a 1.5-MW turbine can power approximately 486 households per year, based on the given capacity factor and assuming the turbine operates at its average rate 40% of the time.
It's important to note that this is a simplified calculation. In reality, the actual number of households a turbine can power can be influenced by many factors, including transmission losses, the efficiency of the grid, and the specific energy consumption patterns of the households being served.
Moreover, the energy produced by wind turbines is often fed into the grid, where it is distributed along with power from other sources. This means that the electricity from a wind turbine may not directly power the households closest to the turbine but could be used to offset the use of fossil fuels and reduce overall carbon emissions across a broader area.
In conclusion, while the exact number of households a wind turbine can power can vary, it is clear that wind energy has the potential to make a significant contribution to our energy needs. As technology advances and the efficiency of wind turbines improves, we can expect this number to increase, further enhancing the role of wind power in our energy mix.

An average 1.5-MW turbine (26.9% capacity factor) would produce the same amount of electric energy as that used by almost 332 households over a year. It must be remembered, though, that wind power is intermittent and variable, so a wind turbine produces power at or above its annual average rate only 40% of the time.
