After decades of harnessing the wind, these turbines are reaching the end of their lifespan. Now producing just a third of their original power output, the aging giants are being dismantled and buried in landfills. This video captures the dramatic demolition and raises important questions about the lifecycle and sustainability of renewable energy infrastructure.

Wrote a letter to the Saskatchewan premier and energy related ministers proposing a temporary moratorium on wind projects that are awaiting approval. The Saskatchewan gov't was not willing to entertain the issue. She questions what the trade offs are, as there are no baseline data sets. There is no ongoing monitoring. Data is needed on normal temperatures and soil moisture content BEFORE installations, and after. Wind and solar cover/surround very arable land. What is happening with the birds and the bats, but particularly insects? What is happening with soil moisture (upwards of 4.4% suspected caused by wind turbines in the grasslands of Mongolia). What plants then survive in those dryer conditions? In Germany they questioned why the efficiency of the wind turbines was diminishing so quickly. What they found was caked insects, several inches thick, on the blades of wind turbines.
Insects migrate. Who knew? Insects use the wind currents to migrate. The wind turbines are located where the wind currents are. Wind turbines could be responsible for the 75% drop in insect biomass on the European continent. But, agriculture was blamed.
