Most of these cost overruns are not caused by inflation but corporate greed just like how the price went up on eggland's Best eggs even though they did not have to do any culling.

fortunately these are all estimated costs and have not actually spent the money and so we can still spend on a solar, wind and battery but I have to say the main benefit is developing this new technology so that we can use it in our colonies off world that we must have as survival of the species requirement. At this point there is no one doing the damage and the Cascade is inevitable. I sincerely hope I'm wrong but that would require the science of climate change to also be and it just doesn't look like it is. We are in the middle of an Extinction event and this planet will likely be a corpse within the next hundreds of years
