Creating jobs is easy: Spend a lot of money and/or make it more effortful to produce things. In either case, workers will be doing more of one thing and less of another.

In this case, more workers are spending more time in "Energy," but this comes at the cost of all the other things those workers might be doing instead. This may or may not be a net-win, but unless we account for the reduced production in other areas, we will delude ourselves about the benefits of these energy jobs.

We will be motivated to keep "creating jobs" simply by shifting workers from one task to another, and then another, regardless of whether those new tasks are actually more valuable to society than the ones they had been doing. We will put in place rules that make production more effortful, because this creates jobs in that field, despite the fact that we will have less overall stuff.
