I just wondered who the intended audience was, and
is there a better expalnation of "rejected energy" and

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

I wonder what lost energy in transportation is? - about 4x the useful
energy!
- energy lost in the power grid?
- inefficiency in vehicle drives?
Must look up the original.
Interesting though.
Chris.

Hello John,
Thanks! That is a pretty nifty diagram.
Sometimes I wonder about the sources for the data though. Example:
Biomass with a paltry 0.6% of all available energy sources supposedly
going into res/comm. Considering that lots of people here in the west
(including us) heat with wood stoves that seems low. For many households
the clear lion's share of energy consumed over a year's time is biomass.
It will be next to impossible to obtain accurate data tracking this kind
of fuel.
Oh, and our favorite brewpub is also heated with a goliath-size wood stove.
Regards, Joerg

Very nicely done.
Perhaps another classic to stand alongside the London Underground map.

One of the great graphs of all time is Minard's map of Napoleon's
march to Moscow and back. In one simple drawing we see the location,
date, size of the army, and temperature. He started with 422,000 men
and finished back in Poland with about 10,000. Six variables are
plotted. It's in Tufte's great book "The Visual Display of
Quantitative Information."

Gasoline and diesel internal combustion engines are notoriously
inefficient, in a range between 5% to 15% efficiency. Most of the
wasted energy is heat out the radiator and the exhaust pipe. |

Is it anything like the Tokyo train/el/subway system? |

Even approaching 40%, for deisel. The trouble is, that this is only at
an ideal operating condition. So for use in a vehicle with varied
conditions, the overall long term average efficiency is somewhat less.

True, but hardly 5-15%.
