1 The Interactive Energy SWOT tool - Model description and adaptation to Spiekeroog - Karl Sperling Dep. of Development and Planning Aalborg University, Denmark Programme meeting Interreg lvb project Cradle to Cradle Islands 7th and 8th October, 2009 Runde Environmental Centre, Runde, Norway

2 Outline for the next hour Part 1: Energy SWOT (Karl) Part 2: SWOT and interactive models (Søren) 2

3 Outline Part 1 1. Interactive Energy SWOT tool (IEST) 2. Background on Spiekeroog 3. Adapting the IEST to Spiekeroog 4. Summary 3

4 Motivation and background Islands often well-defined and/or partially independent systems; e.g. materials, water and energy Manageable amount of quantitative data Possibility of relatively precise input/output analyses Thinking in cycles towards C2C thinking 4

5 Point of departure Energy systems modelling can be complex and requires some technical knowledge Energy model should be useful and user-friendly for participating islands At the same time: need to be able to make sound statements about the energy system Only useful if adapted to the specific context need for interaction and cooperation with the partner islands 5

6 Purpose of the Int. Energy SWOT tool 1. Learning about regional energy flows 2. Assisting in identifying and quantifying problems, inefficiencies and opportunities in the system; i.e. Strengths and Weaknesses 3. Identifying (technical) solutions beneficial from a systems perspective 4. Common language comparisons and exchange of knowledge between the partner islands 6

7 Design of the Int. Energy SWOT tool 7

10 Example: Heat savings To illustrate the impacts in the energy system due to changing one parameter Specify heat savings (e.g. 10%) Reduction in heat demand Reduction in fuel consumption Oil (individual heating) Biomass (district heating) Electricity (Heat pumps Biomass (individual) Reduced CO2 emissions (both internal and external Increase in net electricity export (decrease in import) 10

13 How to adapt the model to an island other than Samsø? 13

14 Spiekeroog # km2 ~800 inhabitants Tourism main source of income Electricity and natural gas supplied through cables/pipeline from mainland 14

15 Spiekeroog #2 17 km2 (90%) protected Nature protection and preservation of the old town (architecture of the houses etc.) have priority 2008: 615,000 overnight stays Vision: independent from mainland s electricity supply Renewable energy share: 7% (mainly from 225 kw wind turbine) Energy conservation and photovoltaic power as possible options 15

16 Spiekeroog #3 Biogas from sewage sludge as an option All heating based on individual gas boilers Cars are prohibited, a few electric cars exist Relatively constant ferry transport demand (2008: 416,00 passengers) 16

17 Adapting the IEST - Main sources of data C2C questionnaire Building register of the municipality Natural gas and electricity consumption estimated through concessions on transmission by utility Information regarding passenger numbers from transport company Information regarding holiday guests from local accommodation association 17

19 Main points The Energy SWOT tool and the actual SWOT analysis are interrelated and simultaneous processes The prerequisites and requirements on the islands limit the (technology) choices to be included in the model The model can then show the effects of these choices If precise data do not exist, missing information has to be estimated 19
