I have watched these Nate Hagens videos you have provided and I think they are great.
I don't think its unreasonable to consider Nate Hagens a bit of an "energy genius" or at least expert.
So it seems that Hagens is under attack because he is not as well known as Al Gore. Here is some of his history that I know. Nate and his writing partner D.J. White are both brilliant. I have actually convinced him in these newer works to tone down the high level language somewhat so that regular people will find it easier to understand. See the list of words below that I was inclined to look up for example. His first masters degree was with honors from the business school at U. Chicago. He went to Wall Street and quickly rose past VP at Lehman Bros. to owning his own investment firm where he managed money for billionaires. He soon realized that his clients were actually quite miserable much of the time and that all of this consumption was ruining the Earth so he walked away from $half a million /year and went hiking with just him and his dog for two years to have time to read and study and clarify his thoughts. He went back to school at U. Vermont and received a PHD in a custom program that allowed him to pursue the seemingly disparate studies of evolutionary neurochemistry/ economy (already a former Wall Street genius)/ energy-petroleum geology/ ecology- resource depletion . How it all fits together (Synthesis). He then went on to write for an emagazine and forum. The Oil Drum.
.
The Oil Drum | Discussions about Energy and Our Future
.
And now teaches Reality 101 as an honors course at U. Minnesota.
.
https://honors.umn.edu/hsem-2624h
.
D.J. White is also an energy expert who saved his money from initially working in oil exploration and got out when he too realized it was a path to an inevitable resource depletion lifestyle as far back as the mid 70's. He decided not to have children and adopt instead. Dolphins. He went back to school to receive certification to set up a dolphin research facility and was instrumental in changing and enforcing worldwide laws for dolphin safe commercial fishing practices. And judging from his language skills in their writing is also a genius although I have never personally spoken to him.

"But saying that depletion is at the basis of our troubles is politically incorrect and unspeakable in the public debate. So, most Italians don't understand the reasons for what's going on. They only perceive that their life is becoming harder and harder, despite what they are being told on TV. Their reaction is to lash out at whoever or whatever they think is the cause of their economic decline"

That's because they wish a huge car with 400km range using standart battery technology. No way... it turns heavy, as it needs a lot of batteries, and if it get heavy if took more energy to run and so as results needs more batteries... A lost case...
It's like try to create a flying elephant.

Maybe it is just much easier for me to understand what he is getting at since I have taken the whole class?

There is a more thorough short video series available now which he just finished and that all incoming freshmen to the Honors College at U of Minnesota are required to view. The production is still slap dash but the information is excellent as usual. Again, he speaks deliberately when narrating so the videos can be watched at 1.5 speed to save time. Watch each group in order. 1, 2, 3. The last few in #3 I find very insightful.

There is no one else that I have ever read that has put together such a complete understanding. And I have read a lot.

I hung in there for about six of the videos.Much was in the 2017 Earth Day video.
Without a table of contents,or index,it's impossible to navigate through the redundant information to get to novel material.
I appreciate what he's done,but I can't take the time to get to the finish.
Thanks for the link.

Thanks for trying. I know a 4 hour video series with 30 videos is a huge amount for anyone to get through which is why I always just start people with the 1 hour lecture (which I happen to think is a good whirlwind tour although he himself doesn't consider it as any thing more than a one time Earth Day talk presented to 40 people and doesn't promote any longer). Hopefully the youtube play list for the longer series is stable so that people can dabble away at it over time when they get bored. I (him also) fully understand that the production is slapped together and contains a few mistakes like inserting the same spoken text twice since it was done with only a couple interns doing the production and under severe time constraints. But at least the information is getting out there.

The Science of Energy

Partner in crime,AeroStealth,loaned me the Great Courses' The Science of Energy,24-lecture series of 2016,with PhD Michael E. Wysession,of Washington University,St. Louis.
I'm in lecture 16 right now,but have a few observations to share.
*while Michael says that fossil fuels dominate our energy landscape and probably will throughout our lifetime,he does discuss transitioning to clean,renewable forms of energy as a matter of health and safety,not to mention climate.
*true costs of coal are 3X the purchase cost.
*China will exhaust their coal by 2045.
*the rest of humanity's future will be dominated by renewable energy.
*anthropogenic greenhouse gases are adding 3-Watts/ meter-squared to Earth's surface.
*Methane is rising faster than carbon dioxide (20X more potent than carbon dioxide),from 715 ppbv (1750),to 1800 ppbv (2015).
*solar output has been decreasing since 1960,and rapidly since 1995,while Earth continues to set records for warmest temperatures in history.
*the last time Earth had today's carbon dioxide atmospheric concentration,sea-levels were 75-100-feet higher.
*while it took 3-weeks for the Larsen-B ice-shelf to collapse,the Wilkins ice shelf disintegrated in one day.
*grid-scale photovoltaic electricity hit economic parity in 2014,at under 10-cents/kWh.
*in 2015,large PV arrays came online at $0.05/kWh.
*in 2015,PVs made their cost back in 2-years or less.
*in 2014,wind-sourced electricity made up 4.4% of total US production.
*in 2014,aside from hydro-electric,wind power was the cheapest form of electric power,compared to coal and natural gas combined cycle-plants,if carbon capture and sequestration were factored in.
*in 2015,some US wind farms' capacity factor were as high as hydro-power (45%-world-wide average).
*while wind turbine rotors kill 200,000-400,000 birds/bats/year,cats kill 1.4-million-to-1.7-million,and cell-phone towers kill about 7-million/year.
*some carbon mitigation geoengineering schemes are estimated at $20-trillion/year.
*Professor Wysession considers it economically advantageous to not release the greenhouse gases in the first place.
*the extant,anthropogenic greenhouse gases will continue to warm the planet for the next 1,000-years,even if all emissions stop today (2015).
*Michael cited the U.S.Energy Information Administration and National Renewable Energy Laboratory of the US Dept. of Energy for data.
PS: passive solar homes would cut domestic power consumption by 50%.
