I hear them saying things about how a small increase in solar panel efficiency is going to completely and rapidly "cure us of our fossil fuel addiction."
We have roughly doubling in solar panel efficiency every 7 years. That's not what I would call "small increase".
Even if solar panels were 100% efficient it would not change the overall picture very much. Solar panels are expensive and do not use space efficiently.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
