I hate that you're posting so confidently in your ignorance.
The video says that the notion that we can't replace fossil fuel with renewables given that we get 80% of our energy from fossil fuels is moot given that we waste two thirds of the energy we create. Thus if we move to renewables which are much more efficient, we only need to replace one third.
I genuinely don't know how you managed to get to your conclusion.
Edit: Seriously, you could've read the last paragraph of the summary and not come away looking as misinformed as you have. You could even look at the thumbnail and not look as imbecilic. I genuinely don't understand why someone would be so eager to say something that they just willingly look…
Edit2: Genuinely curious, in your head, why would someone post something shilling for fossil fuels in the Green Energy community?
