Because the energy density is extremely low compared to ex nuclear. And that it's not just about land use it's also about rare earth materials, the actual production of that many, the installation and maintanance plus no plans for decommision and it still needs ex coal to back it up because it's unrealiable.
- pfdietz 8y agoSolar doesn't use rare earth elements, although that's a favorite fake talking point of the anti-renewable astroturfers.
- ThomPete 8y agoWhat do you call indium, dysprosium, praseodymium, neodymium and terbium, if not rare earth metals?
- pfdietz 8y agoI call them things that are not used in silicon solar panels. Also, indium is not a rare earth element.
- ThomPete 8y agoSo this is wrong?: https://motherboard.vice.com/en_us/article/a3mavb/we-dont-mine-enough-rare-earth-metals-to-replace-fossil-fuels-with-renewable-energy https://motherboard.vice.com/en_us/article/a3mavb/we-dont-mi...
- pfdietz 8y agoYes, it is wrong. Rare earth elements are not used in solar panels. Understand, there's been this obnoxious effort by anti-renewable propagandists to spread the lie that PV is dirty because of rare earths. Shellenberger was spreading this falsehood. But it has no basis in reality.
- ThomPete 8y agovice is pro renewables, so that make no sense. Can you provide som evidence that rare earth metals are not needed?
- pfdietz 8y agoVice is just mistaken, not lying. I will charitably assume the same is true of you. Are you REALLY asking me to prove a negative? Tell me, what purpose do you imagine rare earths serve in silicon PV cells? They are not used as dopants (that's boron and phosphorus). There are no magnets. The glass doesn't require them, nor do the structural metals.
