I've paused the video for a moment because I wanted to first see if there really is such a huge deposit of oil and natural gas in Alaska. It will take me a very long time to watch this if I keep pausing to try and confirm what he's saying!!
Anyway, I found this U.S. Geological Survey:
The U.S. Geological Survey (USGS) recently completed a new assessment of undiscovered oil and gas resources of the central part of the Alaska North Slope and the adjacent offshore area. Using a geology-based assessment methodology, the USGS estimates that there are undiscovered, technically recoverable mean resources of 4.0 billion barrels of oil, 37.5 trillion cubic feet of natural gas, and 478 million barrels of natural gas liquids.
