1) Solar panels are great. But with increasing popularity and aging of the old ones, there is a growing problem of waste. It's not as green as people think. [1]

This is nonsense. Your link says;
"...Contrary to previous assumptions, pollutants such as lead or carcinogenic cadmium can be almost completely washed out of the fragments of solar modules over a period of several months, for example by rainwater...”
But the most modern up-to-date solar panels need NOT have "lead or carcinogenic cadmium", a fact that the link fails to mention thus that link is obviously massively biased against renewables and is just another anti-renewable propaganda site.
There is on-going research into making solar panels out of NEW and better materials and the material they are made of will change over time, thus,, basing what happens to them after they are spent when using current materials when current materials will obviously not be used in the future is flawed.
It is just a question of when, not if, they will be made of non-toxic materials that can be cheaply recycled; what would their argument against renewables be then?
I have read other parts of that weblink that show info in a highly misleading way confirming that its just another of those anti-renewable propaganda sites. What it does is cherry-pick just those fragments of info that makes solar sound like a bad thing while selectively and deliberately filtering out any and all info that makes solar sound like a good thing.
The link, for example, totally ignores the huge pollution from fossil fuels and fails to COMPARE the OVERALL pollution (i.e. INCLUDING air pollution) and resulting death from fossil fuels COMPARED with solar; again, a clear sign it is just another of those anti-renewable propaganda sites.
I have also heard of the usual propaganda nonsense against wind energy; it isn't a big bird killer compared to the birds that are killed via pollution from fossil fuels. If we should ban wind turbines because they kill a few birds then we should certainly ban fossil fuels because they kill a lot of birds.
I should also point out that many birds are killed colliding with trees and aircraft and our buildings such has flats and houses; so we should ban trees and aircraft and buildings?
