    According to the experts in this video it currently takes half a year to offset the emissions related to the production and installation of wind and solar. After that its completely green energy. And solar cells last for at least 20 years.

    So by purchasing from other countries you might outsource a little bit of emissions but save loads compared to running carbon-based plants.

      this dude (french physicist presumably, and big promoter of nuclear) thinks otherwise:

      https://jancovici.com/en/energy-transition/renewables/what-potential-for-solar-energy-and-biomass-energy/

      As a panel has a 25 year life usage, we see that about half the gross production of the whole device goes to the initial energy debt linked to the production of the device. In other terms, if we want to take into account the energy spending required to manufacture the device, it’s rather 5% of France that we should cover with panels.

      because i once took ur position and was confronted with this argument, and now i am confronting this arguemnt against u: nothing personal but just to get hold of facts. also was busy so i couldnt respond same-day, but i kept ur reply in mind.Lemmy is really engaging but can’t let that seep into the rest of my daily-life
