Same with large bodies of water; the ocean, lakes, pools, etc.

I guess in my head I was implying that it was energy humans store for other humans to use at grid scale. When I said "of any kind” I guess that’s not what I meant, lol.
So in my line of thinking, you’re right about e.g. using the sun to heat a rock. But if we use the sun to heat something for electricity generation, or we heat some medium for energy storage, I bet that will be pretty potent.
Besides, past the small scale into the smallEST scale, it’s all just energy anyway, man. 😎
