Can we define “expense”? I consider the loss of public lands extremely expensive. As well as the care and feeding of the carbon based plants required to operate so the base load is maintained. I don’t know numbers, but wouldn’t such an expanse of new solar install demand huge maintenace costs - in areas increasingly prone to natural disaster?
Your first link is from a solar company. Mycle Schneider is a “self-taught anti-nuclear activist”. Cherry picking does make things simple.
But regardless, it’s worth considering the self-fulfilling prophecy. Starting with the state of public discourse leading to tax-incentives heavily favoring solar and wind. And how these articles’ statements exclude all manner of externalities.
