3 Energy strategies
• Build a hyper energy-efficient DC• Network data centres• Energy Demand Management
DC Power Network
• Network DC Power systems
• Generate power by day, consume surplus power by night
• Give control of network to TSO
• TSO can now buy more wind power

Energy Demand Management
• Can’t control supply• => Control demand• => Energy Demand
Management (EDM)
EDM Incentives
• Single Energy Market• Reduced energy costs• Reduced carbon footprint
EDM Strategies
• Demand reduction • Energy time-shift• Demand stimulation
Demand reduction
• Diesel Generators• Heating and • Cooling Thermostat Control
Energy time-shift
• Refrigeration• Ice Bank Air Conditioning• Storage heating• Smart Domestic Appliances
Demand Stimulation
• Swimming Pool Heating • Plug In Hybrid Vehicles • H2 production

Conclusion
• Wind power has massive potential
• Wreaks havoc on grid• EDM can counter the instability
• => Greater use of wind energy
