i don't understand how life is wired and where the power plants are.

how does  the energy supply really work? there are mornings, when I feel refreshed and energetic, others are quite the opposite. i cannot come up with any logic behind it. Maybe we have too many circuits and too many power outages? Maybe a 'bill' is not paid or storms destroy critical junctions within the network?  it looks to me like the voltage, running through our veins, is fluctuating and therefore causes little interruptions or tiny little short circuits. Maybe the wiring is old and used up and a maintenance call is due? Or we have to upgrade our system and adjust to a newer, more modern standards?  I wish the system would come with a manual and some  'what-to-do-if-instructions'. How will i ever find out  otherwise? any ideas?
