I have a 2006 Toyota Rav4 - The other day, the car wouldn't start. We jumped the battery and it started right up. No lights were left on and nothing is plugged in that would be causing this.

For example, it seems switching from some high wattage headlights to much lower wattage LED's frees up more of the alternator's power capacity. But, does this mean the alternator (or other electrical components like the voltage regulator) will start to run hotter? (to dissipate excess power via heat?) Or, does the decrease in overall electrical load simply get handled by just easing up the load on the engine making it easier to spin the alternator in the first place?
