2 Keywords from Obama's 2010 Budget... Cloud Computing Cloud Computing President Obama's 2010 Budget Highlights Cloud Computing President Obama's 2010 Budget Highlights Cloud Computing Energy Efficiency, Green Computing Hidden keywords: Energy Efficiency, Green Computing Smart Grid Smart Grid Hope for the Future: The Smart Grid Is Just What Obama Calls For Hope for the Future: The Smart Grid Is Just What Obama Calls For

3 What is Smart Grid ? “Future Network Vision”, Europe Smart Grid Source : Smart Grid = Power Grid + IT Technology Single direction Flow → Bi-direction Flow

4 Three key components of Smart Grid Source : Silver Springs Network, Smart Home Appliance Ex. Smart Outlet Smart Metering Bi-direction Data Flow MDMS Meter Data Management System

5 What is Smart Outlet ? measure control energy efficiency research Smart Outlet could measure power consumption and control ON/OFF states of the electrical current while we're doing energy efficiency research.

6 Why we need NEW Smart Outlet ? No Vendor Lock-In !! Open Standard. No Vendor Lock-In !! Open Hardware Open Hardware. Cheaper Device... Research of DC-Bus Micro-Grid. (not AC) Power Consumption Measurement Tool for Energy- Efficiency Research. It's kind of FUN!!
