Fracking for Clean Energy (wait, what?)

This was an interesting video and I learned some cool things from it, especially some of the new ideas being tossed around in the geothermal energy space. I also liked that you actually interviewed real experts (reminds of what Veritasium often does, and I think it's nice to break up the awesome visuals with some actual people). Happy to be a subscriber and see what's coming up next. However, I do have some friendly criticism and a few suggestions: 

1) When you were talking about the ecological consequences of fracking, I'm surprised you did not mention perhaps the most important one: huge methane leaks that are driving up global methane emissions to unprecedented levels (see, for example, the work of Cornell ecologist Robert Howarth). This is a big deal precisely because methane is a much more powerful GHG than carbon dioxide. Also, when "King Fracking" mentioned that fracking itself doesn't cause earthquakes but the wastewater disposal does, my eyes rolled over hard. Why was the wastewater being disposed of in the first place? Because of the fracking. I think you were sometimes too deferential to your guests when there were definitely good opportunities for healthy criticism. 

2) This next point is related to that last thought. There are two parts to the title of your channel: "Huge...if true." I would emphasize that last one a lot more going forward. I think it's fine to adopt the implicit perspective that technological innovation is what's going to save humanity from our impending ecological disasters, but you should also acknowledge that there are interesting views on the other side, that many smart people think a lot of these technologies are a waste of time (for various reasons), and that we should focus more on reorganizing the economic structures of our societies rather than on technological tinkering (so things like bringing the oil and gas industry under control through tight regulations, lowering energy consumption, etc). For example, you could've interviewed an ecologist for your video; Howarth would be a good choice actually. He would've had a field day with your other guests. I don't say this to change your mind one way or another, but just to suggest that your channel could benefit from adding content that explores the crazy and dynamic ways that technology, society, and politics all interact and intersect together, instead of just focusing on technical details about specific technologies.
