What makes you say that? There's so much research that flies in the face of this sentiment. Solar on rooftops alone has the potential to supply a fourth of the current US energy consumption [1]. Other studies estimate that solar could grow to supply between 30-50% of our energy consumption in the future [2]. Solar represents a near limitless supply of energy, and can be harvested in a decentralized fashion (allowing homes to directly power themselves).

Furthermore, EVs have shown that advancements in tech can mitigate concerns around material availability and sustainability (while also increasing efficiency).

I'd invite you to review the US DOE Levelized Costs of New Generation [1], which includes both subsidized, and unsubsidized costs.

"Solar is now the cheapest energy in history" - https://www.zmescience.com/science/solar-is-now-the-cheapest...

Really? Most of the numbers I've seen suggest solar is the cheapest energy production there is, so it certainly seems economical.
