19. The Inelasticity of California’s Electrical Supply 0 100 200 300 400 500 600 700 800 200002500030000350004000045000 MW $/MWh Power-exchange market price for electricity versus load (California, Summer 2000)

20. How to Address the Inelasticity of the Supply  Reduce demand, or spread demand over time  Make cost of energy visible to end-user function of load curve  “Real-time pricing” Phase 1: Expose energy usage to user; helps eliminate waste Phase 2: Expose real-time prices to user Phase 3: Automatic control to optimize price, safety, user comfort, other economic goals  Improve efficiency of generation and distribution network (supply side) Enabled by Information!

21. Cory Hall Energy Monitoring Network  50 nodes on 4 th floor  30 sec sampling  250K samples to database over 6 weeks  Moved to Intel Berkeley Lab – come play!
