My understanding is the panels have a long way to go in terms of efficiency and how long they last. The claims of people in the video are for new, truly disruptive sources of energy that are exotic or that work on old systems (like gasoline) but boost efficiencies dozens fold.

I didn’t just mean panels, hydro is solar energy, wind is solar energy, tidal is solar energy, coal is solar energy, even all combustion fuels are solar energy if you consider the oxygen is coming from solar power
