Yes! I created a comment here in similar aspect but the thing that was bugging me a lot was what to do about night time though

Imo, the current system of solar energy etc. might be more carbon emissions than even coal because of the way of using batteries and how they are extracted and the whole process and batteries limitations and not solar panels themselves (I think)

Like, please pardon me but I think that there might be batteries that overall are cheap/economical/less carbon emissions and they can store energy for a night cycle right? Then using those batteries in your system and I don't know the price point, but I am definitely sure that they might be orders of magnitude cheaper

So in your 21M$ example lets say that we can add such night time cheap batteries to counter solar panels not generating light at night and use this 1M$ to generate energy when its either rain or solar production is less or when winters come

I still feel like, this might be more economical than the current state of batteries + solar panels.

Okay, I just realized that the night time issue can be solved by the grid but still if that's the case, then why have batteries in the first case if lets say every community builds something like this (if this is economical) and people could just pull up energy from it 100% solar in rainy times etc.

Like maybe my mind is perfectionist or I genuinely don't know about green energy but to me I wish to know if there is a way that we can transition (almost) 100% to the green (solar) without the drawbacks that I saw in the michael's moore documentary in the sense that it produces more carbon emissions net overall theoretically (which hurts my heart :< but the logic was sound imo)

There aren’t grid-scale batteries that can handle hundreds of thousands of cycles at an affordable price. If we crack that problem, solar and wind for everything will immediately be the only technology worth deploying for energy in 99% of areas.
