I think it's better to have all the power issues sorted out when you build the ship (i.e. install a power plant that can provide all the ship's needs in combat) and just armwave the in-game bookkeeping away like that.
Simpler, but by no means more realistic. In a case such as this, it's better to have the rule to be ignoredby those who choose to than to not have it for those who will. It also means no BBB drive 400 ton 12 laser boats....
I can, in my van, overdraw my alternator and discharge my batteries... by sitting idling with the radio, wipers, rear defog, dome light, and headlights all on. And that's not adding any energy weapons.
The tracking of energy is a feature. It completes the idea started with in HG, that you must account for power usage. (You can't fire weapons while charging up the jump drive, in most HG designs, nor use your agility... since you have to divert power units to hit a target number of them to trigger jump. One can, however, add capacitor banks in HG, each of which holds 20 EP per 1 ton, IIRC, with an EP being 5000MW-minutes... mentioned off-hand in JDrives in HG.)
It's just moving it from an oft-overlooked mention in an obscure rule or three to a prominent place. It makes combat dynamic, and gives us a reason why merchants may choose not to shoot back.
The "pushing" rules give us a way to allow the lower thrust vessel a chance to escape, as well. Also a good thing. In realistic space combat ranges, 1G of difference in thrust means controlling the range to within reaction time... (so, if maneuver is 1 per 6min turn, then it's 6min of accel; if instead it is a 1 minute turn, it's 1 minute).
Being able to divert power from one use to another is also dramatic. (Hell, it's half or more of the drama in the old FASA ship combat systems...)
So, having said that, the 3.2 draft has flaws in how much is generated/drawn. The overall concept, however, is both dramatic and appropriate to the genre and to realism. (And the Type S gets one laser shot with a pulse, or can jump, when her capacitors are full.... after that, she's got to drop thrust, or push the power plant if she wants to do either.)
