is wind turbines,
and how cheaply they make electricity 24/7, and like the batteries in all electric cars, how in an environmentally friendly way can you get rid of them once their life is over? this is the untalked about part of wind farms, the
above photograph is of the municipal landfill in Casper, Wyoming, which is the
final resting place of 870 blades whose days making renewable energy have come
to end, photographer: Benjamin Rasmussen for Bloomberg Green, tens of thousands of aging blades are coming down from steel towers around the
world and most have nowhere to go but landfills, I thought we were supposed to be
cutting down on landfill waste, it seems the wind farm industry is making more!
in the U.S. alone, about 8,000 blades will be removed in each of the next four
years, here at home in Europe, which has been dealing with
the problem longer, has about 3,800 coming down annually through at
least 2022, according to BloombergNEF, and it is going to get worse, most were
built more than a decade ago, when installations were less than a fifth of what
they are now, the fact is that wind power is carbon-free and about 85% of
turbine components, including steel, copper wire, electronics and gearing can
be recycled or reused, but, and it is a big but, the fiberglass blades remain difficult to
dispose of, with some as long as a football field, big rigs can only carry one
at a time, making transportation costs prohibitive for long-distance hauls, so
use more energy cutting them up, and then transport them to, you guessed it, a landfill site! there has been laboratory research into breaking the blades down, but the cost of heating the blades to the temperatures required is prohibitive, wind farms helping to fill landfill sites near you!
