Storage is the bottleneck that makes 100% clean energy even before 2099 unlikely. I recommend the whole video but this part is relevant to my comment: https://

  Link is to a a Stossel TV segment which right out of the gate misrepresents the problem. They cite some staggering numbers about how many batteries you'd need to match "the energy Europe has in storage right now" failing to note that those are petroleum reserves stored for geopolitical insurance, not to buffer instantaneous shortfalls in electricity generation. Those reserves are designed to be many months of use; no one thinks you need that for grid buffering, where a few days is plenty. And in any case that oil is going to be used for vehicle fuel, where the linked article is talking about electrical grid generation. No one thinks we're going to be off of fossil fueled vehicles in a decade, though it's definitely possible to reduce the net usage by a ton. Sorry, that's just a terribly spun video segment. What the linked article claims is absolutely doable.

  Imagine saying this 80 years ago about any number of technologies that are cheap and commonplace today.
