I agree with you, in theory.<p>Practically speaking there hasn&#x27;t been a lot of large scale CSP done, and e.g. Ivanpah[1] has a lot of limitations and teething problems. It has no energy storage, and it needs to use natural gas for 4.5 hours each day during startup.<p>As for your assertion that CSP has continued to grow, the one data point I linked to claims &quot;little appetite&quot; from California utilities for power from plants like that.<p>One thing can probably both agree on is that CSP is a &quot;go big or go home&quot; technology. It&#x27;s not suited for small scale deployments. Which makes it quite complementary to rooftop PV.<p>[1] <a href="http:&#x2F;&#x2F;breakingenergy.com&#x2F;2014&#x2F;10&#x2F;29&#x2F;at-ivanpah-solar-power-plant-energy-production-falling-well-short-of-expectations&#x2F;" rel="nofollow">http:&#x2F;&#x2F;breakingenergy.com&#x2F;2014&#x2F;10&#x2F;29&#x2F;at-ivanpah-solar-power-...</a>
