Wind Turbines Energy Payback Time Varies By Location And Materials
“The energy payback time may vary due to the locations of the wind farm, weather conditions, and due to the variation of the different materials used to construct the wind turbine. Time limits may vary from 6 months to a year to recoup the value from start to finish of building and assembling the wind turbine. My understanding from this document is that, on a badly set up wind farm, they do not produce enough energy to cover the cost of building up and setting up the wind turbine, although on a wind farm that is correctly set up on a good area, there is claims that the wind turbines can produce approximately up to 20 times of energy's value then the cost of manufacturing, building, and setting up the wind turbine. In the construction of the wind turbine, it would be a very important part of the construction to find an ideal location that produces a lot of wind, for example a bad site location with very little to no wind would be a poor choice of site if a wind turbine sits idle or not producing any energy, But a well-chosen site for example with a location of a flat paddock near the coast with lots of sea breeze could help the wind farm produce 20 or more times more energy which would cover the cost. Some materials used to make a wind turbine can be things such as 260 tons of steel, any form of moisture will weaken steel will shorten the lifespan, it usually relies on fossil energy for the need of extreme heat, 300 tons of iron ore, rust and corrosion will shorten the lifespan of iron ore, iron ore relies on fossil energy for the process of creating of the product and 170 tons of coking coal, humidity, or large particles in the coal can shorten the lifespan of coking coal, it relies on fossil fuels to generate the correct heat for the process.”
Summary
Energy payback times for wind turbines generally hover around one year, though they can vary with site wind resources, turbine height, and material choices. Poorly sited farms may fail to recoup construction energy costs, while well‑located turbines often achieve energy returns of roughly twenty times the energy invested. Financial payback periods, however, are typically longer (5–15 years) than the one‑year energy payback.

- Carbon footprint and energy payback time of a micro wind turbine for urban decarbonization planning | Scientific Reports
The effects of system lifetime and hub height on the potential electricity generation were investigated, which identified trade-offs in higher electricity generation for taller turbines yet higher LCGHGE from greater amounts of materials needed. The LCGHGE of micro wind modeled for Austin and Minneapolis range from 53 to 293 g CO2eq/kWh, which is higher than utility-scale wind energy but still lower than fossil fuel sources of electricity. This study highlights the variability in the LCGHGE and energy payback time of micro wind power across locations, demonstrating the value of geospatial analyses for life cycle climate change impact estimates.

Schematic representation of the calculation of the turbine-specific greenhouse gas payback time (GPBT). The GPBT depends on the total emissions during the lifetime of the wind turbine and its power output, as well as the greenhouse gas emissions of the fossil energy reference.
- Public agreement with misinformation about wind farms - PMC
For example, computer-assisted classification of contrarian claims about climate change suggests that conservative think tanks have shifted their focus away from denying climate change toward spreading misinformation about climate-friendly policies and renewable energy8,9. In line with this notion, anti-wind farm lobby groups have gained increasing media traction, many of them leaning on claims that are not sustained by scientific research10,11. Some of this misinformation has been amplified by political leaders, including former President of the United States Donald Trump who described wind turbines as “industrial monstrosities”, has frequently claimed they are ineffective, and once declared that wind turbines cause cancer12.

The deal is an extraordinary transfer of taxpayer dollars to a foreign company for the purposes of boosting the production of fossil fuels, a main driver of climate change, while throttling offshore wind power. It comes as the war in the Middle East has shocked global oil markets, prompting concerns about energy supplies. The New York Times first reported last week that the administration was considering the agreement. Interior Secretary Doug Burgum unveiled the deal on Monday at CERAWeek by S&P Global, an annual energy conference in Houston, where he claimed that wind power was ineffective.
