1 On the way to a 2000-Watt society Zurich s path to sustainable energy use Martina Blum, Energy Expert,

2 Content Introduction and its energy politics How to become a 2000-Watt society Conclusion February 2016, page 2

3 introduction general information Switzerland s largest city and business center residents work places (2x Swiss average) Metropolitan region Zurich: 1.9 Mio. residents work places Legislation is made by Canton and Swiss Confederation Municipalities have a high level of autonomy, according to the principle of subsidiarity February 2016, page 3

4 introduction Zurich is an early mover of energy politics February 2016, page 4 Energy officer, energy savings in city buildings Energy counseling, energy tariffs with saving incentive, energy saving fund Additional energy specifications for buildings Solar exchange for photovoltaics installations, energy services for companies Label Energy City 7-Mile-steps for low impact/energy efficient buildings Label naturemade for green power Energy Master Plan European Energy Award Gold energy tarif revision (e.g. default renewable energy, efficiency bonus) wood-fired cogeneration plant Aubrugg natural power company > Energy % renewable electricity

5 introduction Referendum of 30 November November 2008 Reliable power supply Flourishing economy 76.4 % Yes 2000-Watt-Society goal becomes part of city s constitution YES TO SUSTAINABILITY February 2016, page 5

6 Primary energy (watt per person) Greenhouse Gas Emissions (t per person) introduction 2000-Watt targets according to Energy Masterplan primary energy non-renewable primary energy renewable greenhouse gas emissions reduction targets - PE: factor 2 - GHG: factor 5 80% renewable primary energy long-term goals: PE (primary energy) and GHG (greenhouse gas emissions) all energy sources incl. grey energy part of the balance February 2016, page 6

7 introduction Energy Masterplan February 2016, page 7

8 introduction Local factors influencing 2000-Watt achievement energy companies in city s ownership high volume of mobility / well-established public transport below average living space growing city (inhabitants, workplaces, tourism) February 2016, page 8

9 Substitution Efficiency Sufficiency How to become a 2000-watt society Substitution - strategy of 2000-watt compatible energy supply choosing energy sources with low-carbon and low-primary energy factors, i.e. energy from incineration, waste heat and renewable sources Efficiency - using less energy to serve the same purpose regarding living, working and mobility Sufficiency - reducing the demand for energy-related activities February 2016, page 9

10 Substitution Efficiency Sufficiency Substitution choosing energy sources with low-carbon and lowprimary energy factors photovoltaics solar heat bio-/natural gas heating oil district heating (incineration and wood) biomass nuclear energy hydropower wind solar heat pumps energy from water waste heat Electricity increasing investments in solar and wind details: see ewz strategy «power of tomorrow» Heat using various locally available renewables and waste heat details: see Energy Concept» February 2016, page 10

11 Substitution Efficiency Sufficiency Improving the city s electricity mix electricity company marketing renewable energy products 2006: setting default product on 100% renewable 2015: all products 100% renewable city administration 2006: 100% renewable electricity 2015: 100% «green» certified electricity February 2016, page 11

12 Substitution Efficiency Sufficiency Investments in wind energy Zurich s electorate agreed to investments of 220 Mio. CHF in 2009 Participation at several wind parks, mainly in Germany, France, Sweden and Norway 2015: starting operation in first off-shore investment February 2016, page 12

13 Substitution Efficiency Sufficiency Promoting private investments in photovoltaics New innovative products years solar electricity participation product «ewz.solarzüri», launch 2015 ewz prosumer offer «ewz.meinsolar», launch 2015 Zurich «energy saving fund» (subsidies), commitment since 1989 February 2016, page 13

14 Substitution Efficiency Sufficiency Efficiency using less energy to serve the same purpose Power consumption forecast progress - growing city - shifting towards non-fossil fuels reduction by 5% per inhabitant compared to 1990 February 2016, page 14

15 Substitution Efficiency Sufficiency Efficiency - a city s contribution February 2016, page 15 Set example: building code and energy management for city buidlings, Energy Masterplan, contribution to 2000-Watt site certificate, e.g. Greencity Supporting energy efficient appliances in households and businesses («energy saving fund») Bonus on electricity tarif for energy efficient companies «Energy coaching» and information programs for households, companies and schools

16 Substitution Efficiency Sufficiency Energy Research picture: Luca Zanier Harvesting technological potential and renewable energies is necessary but not sufficient Everybody can contribute to the 2000-Watt goal Research at the interface ot energy efficient technologies and human behaviour February 2016, page 16

17 Substitution Efficiency Sufficiency Business and residential area «Kalkbreite» picture: Volker Schopp opened 2014, private ownership built on public land binding sustainability standards designed for low-ressources and new forms of living together 250 residents, 200 work spaces the areas concept supports sustainable use of ressources low-energy standard below-average private living space (32 m 2 ) spacial community areas car-sharing facilities, no private cars February 2016, page 17

18 conclusion Benefits of 2000-Watt society concept conceptual integration of grey energy allows influence on energy supply consistent methodology (primary energy, GHG emissions) universal application on strategic as well as project level system level view allows to choose from a range of options (efficiency, substitution etc.) February 2016, page 18

19 conclusion A 2000-Watt society is possible 1) Strong Political Commitment and Consistent Legal Framework long term goals as part of municipal law external commitments e.g. European Energy Award help 2) Assertive Implementation and Management energy politics is a cross-sectoral task (challenge in line-organisations) 3) Financial Ressources transition phase: from subsidies to incentive taxes and market solutions February 2016, page 19
