Challenges in Consumer Electronics Energy Efficiency
1) Electronics for Intel and Control2) Non-electronic Functions: Human Senses 3) AC/DC Conversion
Local Energy Area Network
1) Power strips not just extension cords, but to ease management of so many individual devices2) Grouping individual devices based on their network functions3) Reducing vampire power consumption in non-active usage
Consumer Demands Drive Engineering Innovations in Energy Efficiency
1) Consumer experiences dictate higher energy efficiency products demanding engineering innovations2) Consumers adjust their usage patterns to meet energy budget from cellular phones3) Service providers and retailers motivated to promote energy efficient products.
