It's not that use of power that irks me; rather is that batteries and solar panels are placed so far up the tech tree. You're basically stuck with the one-kerbal pod and it's one-shot power supply for far, far too long in the game. IMHO, they should move the basic, non-movable flatscreen solar panel to within the first or second tier at least, along with the smallest battery. Something to let us be able to get out more than one transmission before the battery dies. Yes, yes, I know that running the engine can recharge your battery, but that takes precious fuel and has a habit of wrecking that perfect orbit we worked so hard to achieve.
