From your link: > The Lazard study looked at the “cost of firming,” which consists of building extra capacity to back up solar and wind, for example, leading to an increase in total costs. When included, the economic advantage for solar and wind over gas narrows considerably, and in some cases gas at the low end of the cost curve beats out “firm” solar and wind projects, particularly in California where costs of firming are higher. > The headline LCOE costs look really striking for solar and wind, but when those firming costs are included, renewables “do not look as low-cost as the first LCOE figures imply,” Patiño-Echeverri said. There doesn't need to be a fossil fuel boogeyman behind every decision to continue the status quo. Sometimes the math is the math. Hopefully that will change in the future.
