  • I love the subject, but 225 slides is crazy. I would expect this from the Koch Brothers to confuse the hell out of the viewer by presenting a shallow view of 100 different ideas. No wonder the Hospital went with Gas, they probably made it simple. If there is a next time, my suggestion is to stick with local supply of carbon-free heating, and stop using Drakes Landing as an example. Have you ever wondered why no one else did another Drakes?

  • Hi, I am curious why you are choosing to display the mitigation cost on slide 53 as 3000 Euros per tonne? This makes mitigation look much more expensive than it actually is over 20 years (an assumption) the cost of mitigation is only 150 euros per tonne, which is a lot more affordable. Perhaps 3000 per tonne-year might be clearer.
