More unreliable than the power company? Doubtful. Between Enron-style malfeasance, planned blackouts, commie hackers attacking the power grid, power-line sabotage, old and shoddy infrastructure, etc., there just ain't nothing that unreliable. About friggin time to go off-grid! At the very least, have the damn sense to get rooftop solar panels for backup, and gas or fuel oil for heating/air conditioning. The signs have been clear for years...get a clue now, or sob later.
