Energy Strategy for 2018
• Goals for all Azores– 75% of renewables on electricity production– 40% of renewables on primary energy (electrification of other sectors)
• Plan (for São Miguel)– 3MW Geothermal by 2010– 9MW Wind by 2011– 10MW Geothermal by 2013
• Questions– Another 10 MW Geothermal after 2013?– Storage system?– How to use biomass?– Is this enough? What else?

Engineering a Sustainable Energy System
– Technical dimension• Storage / Smart Grids/ Electric Vehicles / Biomass
– Economic dimension• EU or PPP / Energy markets
– Social dimension• Acceptance / Behavior Changes / Education / Collective welfare
– Critical Infrastructures• Energy /Transportation /Communication
– Energy and Sustainability• Safety /Security
– Fundamentals• Complexity, Uncertainty…

Green Islands Case: TIMES-MARKAL to build scoping scenarios
• Business As Usual– 37 MW Geothermal: [ 24 + 3 + 10 ] (2013)– 5 MW Hydro– 9 MW Wind (2011)
• MPPRen (+ Renewables & Storage)– 47 MW Geothermal: [ 24 + 3 + 10 ] +10 (2013)– 9 MW Hydro [5+4]– 9 MW Wind (2011)– 10 MW Biomass (2013)– 15 MW Pump-Storage (2013)
• MPPRenDom (+ Household Efficiency)– Energy Efficiency Gains from New Appliances– Electricity Demand Growth 2%
• MPPRenAll (+ Lower demand growth)– Non-Electric/Non-Transportation Demand Growth 1%
• MPPRenAllEV (+ Introduction of Electric Vehicles)– 6% of Electric Vehicles in 2013, 30% in 2020

Electricity Scenario for 2018
• Two critical ideas– Reduce energy demand (e.g. energy efficiency in buildings)– Introduce storage systems (e.g. pump-storage or EV)
Storage
Energy Demand

Conclusions
• Engineering a Sustainable Energy System requires– Research:
• Extend modeling and planning tools to include all dynamics
– Implementation:• Energy efficiency (e.g. reduce energy demand in buildings)• Change transportation paradigm (e.g. electrical vehicles)
