  1. Climate Change: We CAN reduce the CO2and other greenhouse gases in our atmosphere to safer levels And now for the GOOD news!

  2. The solutions !

  3. November 2009 That’s ALL the WORLD’s energy

  4. The ‘WWS’ solution: Wind Water Solar November 2009 NOT including: CCS, Nuclear, Other ‘exotic’ sources

  5. HUGE RESOURCES AVAILABLE AVAILABLE TECHNOLOGY COST EFFECTIVE POLITICS BIGGEST OBSTACLE

  6. Tidal Geothermal Hydro 9% Wind Wave 51% NEEDED 11.5 TW Solar Roof PV Concentrated PV Power 40% READILY AVAILABLE 580 TW 85%

  7. NB: Australian coal is cheaper than US power. The REAL problem! Vested interests and confusion/apathy among ‘ordinary people’ – leading to lack of political will.

  8. Australian Solutions! • The big picture: • Solar and Wind • supplemented by • Hydro • Geothermal • Ocean (tidal and wave) • and perhaps ? • Gas • Nuclear (?) • Coal with CCS (??)

  9. Australian Solutions - solar!

  10. Australian Solutions - solar! • The yellow square is about 125 km square • Ample for ALL of Australia’s energy. (At only 10% collection efficiency) [A city uses around 1 PJ per day] 35 PJ per day (=400 GW) That is about 250 Hazelwoods!

  11. Australian Solutions - wind! • “A network of land-based 2.5 MW turbines … operating at as little as 20% of their rated capacity could supply over 40 times current worldwide consumption of electricity” Global potential for wind-generated electricity Lua, McElroy, Kiviluomac, Harvard & Finland, April09 Australia’s 86 PWh = 310,000 PJ/yr (or 850 per day. - Current total energy use is 16 PJ/day) Annual Global potential for wind-generated electricity: Xi Lua, Michael B. McElroya, and JuhaKiviluomac

  12. The Solutions! – World wind power Australia 2008 approx 1,500 MW (14th place) NB: 2.862 means 2,862

  13. Australian Solutions! • Introducing: Beyond Zero Emissions (BZE) Five phase study to achieve zero emissions by 2020: • Stationary Energy* (mostly electricity generation) • Transport • Industrial processes and export • Buildings • Land Use (including agriculture & forestry) * Stationary energy report available now at www.beyondzeroemissions.org (free) or buy today!

  14. Zero Carbon Australia 2020 A plan for repowering Australia with 100% renewable energy in ten years

  15. Key Questions: Who are Beyond Zero Emissions? Zero Carbon Australia Plan What are we calling for and why? 100% renewable energy by 2020 How can we get there? Wind and Baseload Solar Thermal Can it be done? Yes. Fully modelled and costed, using existing commercial technologies

  16. TheCAN'T DOcampaign Oil and Gas Generators Coal exporters The CAN'T DO MANTRA “Renewable energy cant supply baseload power” “Renewable energy is too expensive” “Renewable energy will wreck the economy” “Renewable energy will cost jobs”

  17. The ZCA 2020 ‘CAN DO’ team

  18. "Australia has one of the world's best solar energy resource, ... The Zero Carbon Australia Plan is based on up-to-date and sound information and provides quality insights on how a country well-endowed in renewable resources can transition to a solar and wind economy.” Cédric Philibert Renewable Energy Division International Energy Agency "This report will help shift the climate debate to focus on energy; security; affordability; export and of course opportunity” Professor Robin Batterham, President, Australian Academy of Technological Sciences and Engineering, formerly Chief Scientist of Australia “We have the resources. We need the will.” Dr. Peter Doherty, Nobel Laureate, School of Medicine, University of Melbourne

  19. TheCAN DO Campaign • Accepts current climate science evidence on what has to be done & by when • Uses only existing commercially available technology. We have all the tools NOW • Meets Australia’s total energy demand • with 100% Renewable Energy by 2020

  20. FIVE REPORTS: Stationary energy Transport Buildings Agriculture Industry

  21. Carbon Budget 2010-2050 Why ten years? “Limiting CO2 emissions to 1 trillion tonnes* by 2050 gives us a 75% chance of keeping global warming below 2oC” * 2000 - 2050 Meinshausen, et al. (2009): Greenhouse-gas emission targets for limiting global warming to 2oC. Nature 458, 30 April 2009 SEE ALSO www.PRIMAP.org

  22. Why ten years? Carbon Budget 2010-2050 Most of Europe

  23. Why ten years? Al Gore calls for 100% clean electricity and independence from foreign oil within ten years “a political promise to do something 40 years from now is universally ignored because everyone knows that it's meaningless. Ten years is about the maximum time that we as a nation can hold a steady aim and hit our target.”

  24. Why ten years? Thomas Friedman: Three reasons for going renewable - End dependence on, and financing of, the “dictators and terrorists in the Middle East” ‘Peak oil’ will mean higher prices, yet more political tension. If we divide the total of the world’s oil reserves by the rate at which WE are using them we get about 12 years (7 for USA use) And to save us from a climate catastrophe!!
