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.

27. 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

28. A technically robust scenario in which the UK
has risen to the challenge of climate change.

29. Net zero across all greenhouse gas emissions
(not just energy), using technology we have now.

31. From this …

32. … to this

33. Without major impacts on quality of life (in fact,
we think this future looks pretty good)

34. We have to see the future like this
No ‘business
as usual’ future
is available.

77. Grow all the biomass need

78. Capture remaining carbon
Safe, proven, long-
lasting methods:
• Restore 50%
of peatlands
• Double forest area
• More use of UK

79. This is how it works.
