DESCRIPTION:*Abstract*: What do the fundamental limits of physics say abou
 t sustainable energy? The British Isles\, we often hear\, have `huge` rene
 wable resources - but we need to know how this `huge` source compares with
  another `huge`: our huge power consumption. The public discussion of ener
 gy policy needs numbers\, not adjectives. Assuming no economic constraints
 \, assuming we cover the country with windmills and the coast with wave-ma
 chines\, every roof with solar panels and every field with energy crops\, 
 could Britain get enough power from renewables to continue with our curren
 t consumption?\n\n*Biography*: David MacKay is a Professor in the Departme
 nt of Physics at the University of Cambridge. He studied Natural Sciences 
 at Cambridge then obtained his PhD in Computation and Neural Systems at th
 e California Institute of Technology. He is internationally known for his 
 research in machine learning\, information theory\, and communication syst
 ems\, including the invention of Dasher\, a software interface that enable
 s efficient communication in any language with any muscle. He has taught P
 hysics in Cambridge since 1995. Since 2005\, he has devoted increasing amo
 unts of time to public teaching about energy. He is a member of the World 
 Economic Forum Global Agenda Council on Climate Change.\n
