Re: None Renewable Rare Earth-Friendly Elements, Mined Destructively

I agree however its these rare elements that make these turbines much more efficient, without them you lose efficiency greatly and these elements are not renewable and will increase in costs exponentially and decrease in availability until they are all very rare if wind turbines are scattered ungracefully across the planet! All and all wind farms are not as earth friendly as claimed and not as user friendly as claimed, the noise pollution from these farms is enough to drive a man insane !

"There are 17 rare-earth elements — some of which, despite the name, are not particularly rare — but two heavy rare earths, dysprosium and terbium, are in especially short supply, mainly because they have emerged as the miracle ingredients of green energy products. Tiny quantities of dysprosium can make magnets in electric motors lighter by 90 percent, while terbium can help cut the electricity usage of lights by 80 percent. Dysprosium prices have climbed nearly sevenfold since 2003, to $53 a pound. Terbium prices quadrupled from 2003 to 2008, peaking at $407 a pound, before slumping in the global economic crisis to $205 a pound." Tweet
