  1. GN3 Green networking workshop– Zero carbon: renewable energy Teleworking JørgenMoth, UNI-C SURFnet, Utrecht 5-6 March 2012

  2. Zerocarbon:Cleanelectricity

  3. Zerocarbon:Import cleanelectricity

  4. Zerocarbon:Move power or data? HVDC cableNorway-Netherland : Transporting power for a 1MW data center costsabout 30kW (3% loss) Move the data center to Norway and use an optical link: Opticalamplificationcostsabout 1kW

  5. Zero Carbon:Teleworking – move data instead of people 0,5% ?

  6. Zero carbon:Smart 2020 anticipations and claims

  7. Zero carbon:Teleworking- Exercise • “SMART 2020” claims: • Enabled by wired or wireless networks, teleworking may save 0,26 Gt CO2e/year out of 51,9 Gt in 2020 • Try to support this claim: • Estimate the number of days working from home and calculate the transportation emission savings.

  8. Zero carbon:Teleworking– emission factors • Public Danish emission factors are used: • Car – 175 g CO2e / km • Bus – 90 g CO2e / passenger km • Regional train – 42 g CO2e / passenger km • Metro – 16 g CO2e / passenger km

  9. Zero carbon:Teleworking– UNI-C study results • 319 kg in 5 weeks scales to about 3 tonnes per year for 30 employees • Each Dane emits about 10 tonnes of CO2e per year • 3 tonnes is a 1% reduction of the 300 tonnes for 30 employees • The SMART 2020 claim is ½ % of the “business as usual” estimate of year 2020. • Our study thus supports this claim • An extra gain of this study has been to raise the GHG emission awareness of UNI-C’s employees
