How information and energy are connected


We talk about conserving energy in our households by turning off lights. But energy is always conserved, it’s a law of nature. What we are trying to conserve is usable energy. What’s the difference between usable and unusable energy? The answer is that usable energy is energy where we know what direction it is headed. Unusable energy is energy that we no longer know what it’s doing. What has been lost is not energy but knowledge. We are trying to conserve not energy, but knowledge of the truth. Since our lights can’t run on the one kind of energy but they can run on the other, you could say that they don’t run on energy, but truth.
