Thank you for offering an explanation, its a good analogy.
I agree that energy can be viewed as like money, unfortunately, there is a problem in this analogy.
As I see it, the currency or money is has a number or value say £1.50, this remains the same what ever form it comes in, paper, copper or alloy.
Perhaps the analogy could be refined - energy is more like wealth. You can have it in cash, material possessions, land, even political power & influence. One form of wealth can be converted to another, and it can be used to get things done. If I use my cash to build a house, I most of that cash is converted to material property wealth, but there are always some losses in the conversion, e.g. breakages, spoilage, trimmings (excess wages, fraud, taxes?). In this analogy, the total amount of wealth always remains the same, but high-quality wealth, like cash, becomes degraded with use, becoming less usable, until ultimately you end up with lots of undesirable, hard-to-shift wealth, like scrap, IOUs, vague promises, rubbish, etc. Like most analogies, it's the concept that is important, not the detail.
I dunno how helpful this is likely to be - you only need to read and contemplate the implications of the basic physics explanations online to understand what energy, work, force, etc., are. I suspect that punshhh is being so obtuse, if not deliberately, through lack of effort, not lack of capacity.
