  1. Supplying the world entirely with renewable resources Emily Rochon Greenpeace International October 27, 2015

  2. Greenpeace is an independent global campaigning organisation that acts to change attitudes and behaviour, to protect and conserve the environment and to promote peace. Greenpeace is present in more than 55 countries across Europe, the Americas, Asia, Africa and the Pacific. To maintain its independence, Greenpeace does not accept donations from governments or corporations but relies on contributions from individual supporters and foundation grants.

  3. Why do we need to change the way energy is produced and used? Let me count the ways… • The current energy system results in: • Climate change • Public health issues • Water scarcity and pollution • Energy insecurity and war • Oil spills • Air pollution • Acid mine drainage • Rising and unpredictable costs • Nuclear accidents/waste disposal problems • Etc…

  4. Avoiding catastrophic climate change means staying below 2o C • Global GHG emissions must decrease by at least 80% by 2050 • To get there, energy sector (electricity, heating and transport) must be decarbonized

  5. Is 100% renewable energy possible? RE Final Energy share: 2012: 19% // 2020: 23% // 2030: 42% // 2050: 100%

  6. The E[R] Power Sector Logic

  7. The E[R] Power Sector Logic

  8. How to get to 100% renewable energy by 20501. Phase out fossil fuels - Lignite (2035), coal (2045), oil and gas (2050)2. Phase out nuclear (2050)3. Reduce energy demand (15% below current levels)4. Increase renewables - Solar PV, Wind (8,040 GW), CSP, hydropower, geothermal, ocean, hydrogen, synthetic fuels, biomass/biofuels5. Electrify large portion of heating (19+%) and transport demand (53%)6. Build a smart grid, rely on energy storage, and reform energy markets

  9. Global : Power Sector RE electricity share: 2012: 21% // 2020: 32% // 2030: 64% // 2050: 100%

  10. Benefits of 100% power sector: • Money: Fuel costs savings means 100% RE is less expensive than BAU • Jobs: Greater employment and economic development opportunities • Safe climate: Only way to stay below 2 degrees C warming

  11. Money Additional Investment Costs – Entirely Refinanced by Fuel Cost Savings

  12. Jobs

  13. Climate % of 1990 emissions: 2012: 146% // 2020: 145% // 2030: 96% // 2040: 39% // 2050: 0%

  14. 100% renewable energy by 2050 is:1. Technically and economically achievable2. Only way to avoid catastrophic climate change3. Will result in more jobs in the energy sector4. Less expensive overall than business-as-usual5. A ready solution for access issues and energy supply shortages 5 Takeaways
