These slides come from the presentation made by Tobi Kellner and Alice Hooker-Stroud at the ZCB Event: "Can renewables keep the lights on?" held at St John's church, Waterloo, London on the 9th April 2014.

They outline the Zero Carbon Britain: Rethinking the Future scenario detailing how the UK can rise to the climate challenge and run on net zero emissions. It includes questions posed to the audience for a 'world cafe' style discussion that followed the presentation sessions.

  6. 6. Can we ‘keep the lights on’ with a 100% renewable and carbon neutral energy system? Can we provide a healthy low-carbon diet for the UK population? New research
  7. 7. A technically robust scenario in which the UK has risen to the challenge of climate change.
  8. 8. Net zero across all greenhouse gas emissions (not just energy), using technology we have now.
  9. 9. From this …
  10. 10. … to this
  11. 11. Without major impacts on quality of life (in fact, we think this future looks pretty good)
  12. 12. We have to see the future like this No ‘business as usual’ future is available.

  36. 36. Food + diets model: nutrition, emissions, land
  37. 37. Change our diets
  38. 38. Change our diets • Switch high protein foods 5-6 portions meat/dairy/eggs. 4 portions ‘alternatives’ (beans, pulses etc). + Milk for tea/coffee.
  39. 39. Change our diets + halve food waste + improve agricultural practices = Emissions - 75%

  41. 41. Grow all the biomass need
  42. 42. Capture remaining carbon Safe, proven, long- lasting methods: • Restore 50% of peatlands • Double forest area • More use of UK wood products
  43. 43. This is how it works.
  44. 44. Net zero GHG emissions is possible. • Using technology available now. • Without major impacts on quality of life.
  45. 45. We can provide a reliable energy supply. • 100% renewable/carbon-neutral. • No nuclear, no fossil fuels. • Using technology available today. ZCB also shows that
