Solar power was a novelty that was dismissed as a fad. Thousands employed it so they wouldn’t contribute to the worsening fossil fuel pollution.
Solar power advanced until it was a pragmatic solution for inconvenient places like ranches and outposts.
Solar power has now advanced to the point that, for some regions, it is more expensive to use coal than solar. The added benefits: autonomy, local jobs, an intimate awareness of daily energy use.
Subsidies sway the boundary, but even if they fade, solar efficiencies will progress.
