The world will have to deal with 43 million tons of decommissioned wind turbine blades by Net Zero in 2050. To put that in perspective, it’s the equivalent weight of 215,000 locomotives. These blades are made of high-strength composites designed to survive decades of brutal weather, and they are notoriously difficult to recycle. They were built to last, but they weren't built to disappear. Every turbine standing today will likely be decommissioned and replaced at least once before 2050. Without a cost-effective way to recycle fibre-reinforced polymers, the majority of these massive blades are destined for eternity - buried forever in turbine graveyards. China, Europe, and the US will account for the vast majority of this waste, creating a mountainous industrial heartache that many Net Zero models simply haven't priced in. But 43 million tons of purely composite blade waste every 20 years is a colossal physical reality.
I FULLY support increasing teachers pay, but… this is not about teachers pay. Dems have co-opted teachers around the country into protesting against the current administration. All in the name of an obvious issue, low salaries. It’s smoke and mirrors, folks. The number of administrators has grown 20 times larger than the number of students. Admissions are declining. Literacy is declining. The real answer if you actually care about teachers… Mass deportations and firing of bloated administrations.
It is unusual for soon-to-be-former Fed Chair Jay Powell to stay on at the @federalreserve. For someone who speaks so often of norms, his unilateral decision to stay flies in the face of tradition. Kevin Warsh will bring about a new day at the Fed, with accountability, management, and sound policymaking in the lead.
