You're kind of making OPs point though - that post was written by a retired 80yr oil engineer who just blogs into the aether because he hates solar and wind.. the $5 trillion estimate was him literally just making up numbers.

To critique this more specifically - in that post he assumed we would spend $5 trillion on batteries, and they would still cost the same $200/kwh that they cost in back in 2018. Even if his other assumptions on the capacity required were valid (they aren't), costs have already fallen below $100/kwh since learning curves exist - so his scary $5 trillion number is already below $2.5 trillion. Add in the additional cost savings and amortize that investment over a decade and you're talking about maybe 3.5% of the Federal budget?
