The harder thing would be to explain why your species continues to get energy by burning things despite having multiple alternatives and that many people are deeply ideologically opposed to moving away from burning things.

Imagine the type II alien nods with understanding in a human way that your species just isn't ready and it might not ever be as it erases your memory of the encounter and returns to the stars, stopping only to scan your anal sphincter because all the type II civilizations remain puzzled by it.

I think they'd give you some leeway if you fired up gas plants to not freeze in the winter, I want to see their faces when you tell them you turned them on because you wanted to generate more digital slop during a climate crisis

Imagine they got here without burning anything, ever, in the history of their species.
