Notes From All Over, Part 3 -- August 8, 2019

Plastic straws? LOL.

Earlier we posted the "Michael Moore woke" story.

From The WSJ: if you want renewable energy, get ready to dig.
  • one wind turbine -- one --
    • 900 tons of steel
    • 2,500 tons of concrete
    • 45 tons of plastic
  • the amount of CO2 emitted building/installing a wind turbine -- that wind turbine will never save that much CO2 over its expected 7-year lifetime
From the op-ed:
“Renewable energy” is a misnomer. Wind and solar machines and batteries are built from nonrenewable materials. And they wear out. Old equipment must be decommissioned, generating millions of tons of waste. The International Renewable Energy Agency calculates that solar goals for 2050 consistent with the Paris Accords will result in old-panel disposal constituting more than double the tonnage of all today’s global plastic waste. Consider some other sobering numbers:
A single electric-car battery weighs about 1,000 pounds. Fabricating one requires digging up, moving and processing more than 500,000 pounds of raw materials somewhere on the planet. The alternative? Use gasoline and extract one-tenth as much total tonnage to deliver the same number of vehicle-miles over the battery’s seven-year life.
When electricity comes from wind or solar machines, every unit of energy produced, or mile traveled, requires far more materials and land than fossil fuels. That physical reality is literally visible: A wind or solar farm stretching to the horizon can be replaced by a handful of gas-fired turbines, each no bigger than a tractor-trailer.
Building one wind turbine requires 900 tons of steel, 2,500 tons of concrete and 45 tons of nonrecyclable plastic. Solar power requires even more cement, steel and glass—not to mention other metals. Global silver and indium mining will jump 250% and 1,200% respectively over the next couple of decades to provide the materials necessary to build the number of solar panels, the International Energy Agency forecasts.
World demand for rare-earth elements—which aren’t rare but are rarely mined in America—will rise 300% to 1,000% by 2050 to meet the Paris green goals. If electric vehicles replace conventional cars, demand for cobalt and lithium, will rise more than 20-fold. That doesn’t count batteries to back up wind and solar grids.
So much more at the link.

My hunch: Michael Moore  has a copy of this article in his scrapbook.

There is a reason that wind energy is collapsing in Germany.
