SG-W:/ City Density versus travel energy



    This information was taken from an Email from energyresources. It typifies the information we need to tell the public that conservation is better than crazy energy production schemes. The attachment may not survive but it contains the formatted info that would be useful as a passout sheet to students or public officials.

                  A table from an E-mail
 
      This information is from an Email from Murray Duffin. Note the radical decrease in energy consumption as cities grow denser. Hong Kong is the most vertical city and its dwellers consume the least energy. Note the huge difference between Houston, the only American city and all the others. One MJ=one million Joules=947.8 btus. Ha is hectare or about 2.47 acres. Inhab means inhabitants, trans means transportation and GDP means Gross Domestic Product.

                         Urban Travel Energy
 
     The following table is from a study entitled "Urban Growth vs
 Sustainable Mobility" By the Sustainable Development Working Group of
 the International association of Public Transport, published
in "Sustainable Development International", Summer 2003. The figures are for personal transport, and do not include goods and services.
     I have personally lived in Hong Kong, Paris, and London, and have
 frequently visited Tokyo, Munich and Houston. I can attest that for
 the urban dweller, Houston is the least livable of these cities, and
 Hong Kong is not bad. Hong Kong is by far the most vertical. Overall
 I would prefer Paris.   by Murray Duffin
