Great discussion, was wondering if you could enable comments on the other videos

Mr. Armstrong asked some very thought provoking questions. Mr. Birol had a great presentation also. I wish he spoke more on the current hydrogen infrastructure we have in place, as that has increased in popularity over the past few months. But overall, a very informative video about the future of global energy. Thank you MIT!

Great presentation - in particular (around 15 minutes in) when you discuss Tacking Emissions from Existing Infrastructure .. Opportunity wise this is not a low hanging fruit -- this is a field of watermelons on the ground ready to be picked. Every single piece of equipment that is now in service can be upgraded in some way to make it more efficient/cleaner/leaner and cost effective. A lot of the "big metal" infrastructure was put in place before "externalities" like emissions, water use, solid waste and other drivers of climate change and environmental degradation were part of the equation. The global installed base has to be remanufactured/repowered/retrofitted and upgraded to current technology and performance standards. This is cheaper than replacing it with new, it avoids "the valley of death" associated with brand new greenfield technology roll-outs (and the permitting process) -- and it makes economic sense. Jobs for upgrades and maintenance are created locally (you can't move these facilities to get upgraded). We need to recognize this opportunity and provide the regulatory and financial incentives to scale up the upgrade and modification efforts so that we can reach the gigaton scales of emissions reductions needed to reach "net zero" anytime in the future.

IEA predictions have failed year after year, why should we believe these ones?...
