Summary:

- The article discusses the importance of maintaining "clean firm power" as a crucial component of a sustainable energy mix. Clean firm power refers to reliable, dispatchable, and low-emission energy sources that can provide consistent power generation.

- The author argues that while renewable energy sources like solar and wind are essential, they are inherently intermittent and require backup from reliable, dispatchable power sources to ensure a stable and resilient energy grid.

- The article emphasizes the need to maintain and invest in clean firm power sources, such as nuclear, hydroelectric, and natural gas with carbon capture and storage, to complement the growth of renewable energy and achieve a balanced, sustainable energy system.
