They did... two different ways; tax basis and financial reporting basis (i.e. DD&A / book value).
But that's not really the issue. The issue is which one is more efficient and effective. The high energy density of fossil fuels makes it more efficient and effective than solar or wind. Water is a different story and nuclear is an all together different story.
The way I see it is that wind, solar and water all have a niche, but that niche won't base load the country's energy needs. I think renewables/green energy has a role. So does conservation. EV's and ICE vehicles will coexist and each will serve a purpose.
But that's not how those idiots are messaging it. What they are messaging will never and can never happen. It's idiotic. I can't believe how many idiots believe it.
