Personally I believe all the 'microplastic' stuff is just alarmism and 80% of it is due to countries that dispose of their waste improperly like China.

But the EROEI (I hate using that term since the eco-doomers like it) on solar panels in particular is very low. Wind turbines are better. But the best energy source we currently have is natural gas. The next step should be either mass-produced nuclear fission with thorium, or nuclear fusion.
