DESCRIPTION:Energy and climate change – they’re in the news\, they’r
 e ‘huge’. Consumption is huge. Economic growth is huge. Our population
  density is huge. CO2 pollution? Huge! Potential of renewable power? Huge!
  Nuclear power? That’s huge too – and hugely costly to clean up… How
  to fix all these problems? Well\, if only everyone turned off their mobil
 e phone chargers\, we’d be well on our way to a solution. Oh yes\, and l
 et’s remember to drive hydrogen-powered cars\, like Arnold Schwarzenegge
 r. That’ll help. And don’t forget magnetic levitation\, that’ll elim
 inate friction. And if you must burn fossil fuels\, good old B.P. can neut
 ralize your CO2 emissions if you pay them just 6 euros per tonne.\n\nPoppy
 cock.\n\n“Every little bit helps!”\n\nPoppycock!\n\nTo understand thes
 e ‘huge’ issues\, we need numbers\, not adjectives. And we need number
 s that are simple\, human-sized\, and memorable. No millions\, no billions
 \, no Terawatt hours\, no exajoules. In this talk I’ll present simple ba
 ck-of-envelope calculations to see how our energy consumption stacks up co
 mpared with conceivable sustainable production.\n
