In ~90% of the time, when people are talking about energy, they should actually be talking about entropy.
There is a wonderful new video about "The Most Misunderstood Concept in Physics" - Entropy
by @veritasium
Though, actually I would say ENERGY is the most misunderstood concept and as a consequence ENTROPY is the most neglected one.

Simulation is the best way to learn anything, and I would highly recommended using it to learn why it's cold up on mountains.
Why is it really cold in the mountains?
It sounds like a simple question, but it is actually really not that trivial.
I did a lot of digging, and came up with a few simple interactive simulation models to illustrate some key concepts, that lead to cold mountains. #ScieneTwitter
You can find the full story on my website:

In this simulation, for example, white dots represent visible light, and the orange dots represent heat radiation. The heat radiation is stochastically emitted based on the temperate of each slab, which is indicated by its color.
