No, that's a terrible analogy. Stored Energy is an intrinsic physical property of all materials.
Value on the other hand, is purely subjective.
One can measure the exact amount of energy contained in a gallon of oil. You can get a precise number, and that number will be accurate and not change(not for a long time anyway).
On the other hand, you cannot do this with value. I have repeatedly asked someone to try and do this ...and no one has been able to. Why is no one able to exactly quantify the value of an ounce of gold? (Hint: Because it is subjective and constantly changing)
No, you can't measure it, because EVERYTHING ELSE is changing. Humans hold the value of their medium of exchange constant. This is why people don't notice inflation. They think that prices are just going up. When the value of EVERYTHING is changing, you can always set one thing as constant. What you chose as your constant determines the stability of pricing. Endlessly reproducible paper notes, rare nearly indestructible gems, or indestructible, rare, easily divisible metals will each have different amounts of inherent value when set as a constant which can be measured by the amount of fluctuation in prices when the value of other materials is set in terms of that material.
We consider gold to have a high intrinsic value TO HUMANS because it is ALWAYS valued as a means of exchange, though the Western World has managed to usurp the laws of nature for the last generation or so, which has obscured the intrinsic value of gold as universal currency and given that property to endlessly reproducible paper notes. This has brought to the fore the difference between price and value. Goods and services can be priced in dollars, but those dollars have no value, save by declaration of the state. The paper has little intrinsic value (what little it has is due to its usefulness as kindling or wallpaper), because it can be reproduced easily.
Gold has a lot of intrinsic value, because when you buy something with gold, what you buy has been assigned a value in gold by the transaction. When you buy something with paper, you "pay the price" so to speak. Rather than trading something that is inherently valuable, you have traded something that that only costs 4 cents per bill for goods. Although the price is set as such, the value you are exchanging for those goods is easily influenced by the government. The paper you trade only has a value of 4 cents per bill, regardless of the denomination. Rather than trading something that is inherently valuable, you are trading based on the honor of the government, literally credit.
Gold is inherently valuable because one ounce of gold costs as much as one ounce of gold. Fiat dollars are not valuable because one bill (whether a one or a hundred) costs four cents. Other mediums of exchange tend to be less inherently valuable than gold because they can be produced fairly easily (paper, beads, round stones, etc.), or they are more vulnerable to destruction (silver oxidizes more readily, and is used up by industry).
All of this is predicated on the existence of human society.
