Summary:
This paper is about system and power usage.  The system design is based on negative feedback.  They use a kitchen as an example.  When an appliance is used with poor power management, the user will get a verbal rebuke, or even a text message.  Also, the system will be given enough control to reduce power drain of certain appliances that have been misused in the past.

Discussion:
I think that this system could be useful.  Most people probably don't even realize  when they are using appliances poorly.  This would give them a chance to fix that, and save some money on electricity bills.  That being said, I am not sure that only negative reinforcement is the best option.  There are people that don't react well to negative reinforcement.  I would think that a mix between positive and negative reinforcement would be better.
