1. Team Tidewater Status Update 12NOV2012

2.  Appliance Analysis  Got the average yearly usage from internet sources ◦ Broke it down to kWh/day and /usage  Determine the Max Energy Consumption for Competition ◦ Measured Test  Different testing procedures per appliance  Water and electrical consumption ◦ Dinner Party  How many people eating  How often each appliance is used  US average residential rate $0.1151 kWh ◦ At 135 kWh it will cost us $16.15 to operate at peak performance
