Sorry if I'm repeat posting, but this is really good news.

A topflight science brainbox at Cambridge University has weighed into
the ever-louder and more unruly climate/energy debate with several
things that so far have been mostly lacking: hard numbers, willingness
to upset all sides, and an attempt to see whether the various agendas
put forward would actually stack up.
Professor David J C MacKay of the Cambridge University Department of
Physics holds a PhD in computation from Cal Tech and a starred first in
Physics, so we can take it that he knows his numbers. And, as he points
out, numbers are typically lacking in current discussion around carbon
emissions and energy use.
MacKay tells The Reg that he was first drawn into this field by the
constant suggestion — from the Beeb, parts of the government etc — that
we can seriously impact our personal energy consumption by doing such
things as turning our TVs off standby or unplugging our mobile-phone
chargers.
Anyone with even a slight grasp of energy units should know that this is
madness. Skipping one bath saves as much energy as leaving your TV off
standby for over six months. People who wash regularly, wear clean
clothes, consume hot food or drink, use powered transport of any kind
and live in warm houses have no need to worry about the energy they use
to power their electronics; it’s insignificant compared to the other
things.
Most of us don’t see basic hygiene, decent food and warm houses as
sinful luxuries, but as things we can reasonably expect to have. This
means that society as a whole needs a lot of energy, which led MacKay to
consider how this might realistically be supplied in a low-carbon
fashion. He’s coming at the issues from a green/ecological viewpoint,
but climate-change sceptics who are nonetheless concerned about Blighty
becoming dependent on Russian gas and Saudi oil — as the North Sea
starts to play out — will also find his analysis interesting.
Eliminating carbon largely equates to eliminating gas and oil use.
“I don’t really mind too much what your plan is,” MacKay told The Reg
this week. “But it’s got to add up.”
