Wind turbines are ageing – what happens next?$this->bbcode_second_pass_quote('', 'W')ith an average lifespan of 25 years, a high proportion of wind turbines across the world are approaching retirement. What happens to their components after they are decommissioned?
...The world’s first windfarm was erected in New Hampshire, US, in 1980 and was 20 turbines strong. It was followed by the first offshore windfarm in Vindeby, Denmark, in 1991, along with the first onshore windfarm in Cornwall, UK, also in 1991.
Since then, wind turbines have been erected across the world, heralded as a crucial part of the solution to the green transition. GlobalData estimates that there are currently over 329,000 active turbines worldwide, with almost 200,000 more in the pipeline. Decommissioning a wind turbine is not a straightforward process. The turbine must be disconnected from the grid, which requires permits and approvals from the relevant authorities and stakeholders. After this, the turbine must be removed from its site.
“Once the turbine is decommissioned, cranes and other equipment are used for the removal of the systems,” says Singh. “Some project infrastructure, like overhead lines, underground lines and substations, may be reused. Turbines are dismantled and the parts are removed. The blades, nacelle, or housing for components related to the generation of electricity and the tower are all fully removed from the site. Cables that are part of the collection system, as well as transformers, are also removed.
“Turbine foundations are removed so that land can be returned to an agricultural use. The majority of the turbine components, like concrete and metals, make their way to recycling plants, but many components like blades are disposed of at landfills.”
Turbine foundations are removed so that land can be returned to an agricultural use? Well I guess the stresses imposed on them over the decades would weaken the concrete. but I cant see them demolishing hundreds of thousands of those. They will just be left behind like all the other shit lol. Like the spent reactor fuel is left behind when those plants are decommissioned, too expensive to do anything else. But have you ever seen how much steel and concrete goes into one of these bases?
$this->bbcode_second_pass_quote('', '[')b]Blue Creek Wind Farm in Ohio- The construction of 15 to 20-foot-deep concrete foundations to support all of the 328-foot-high towers with 2-MW turbines required 30,000 tons of cement. On average, each of these below-ground support systems used 60 truckloads of concrete (750 yd3),
