[Greenbuilding] Energy Numbers

[Gennaro Brooks-Church - Eco Brooklyn]

To add to the mix I found this file while looking up the validity of one
barrel of oil equaling over ten years of a person's physical labor, which
appears to be a valid claim and for me is the largest reason we have sped
up over the past 100 years. My question now is whether we can keep the
speed by transitioning to smart technology or whether we should begin
learning how to "age gracefully"....personally I am all for slowing
everything down regardless of whether we can keep the speed....but maybe
that is me getting older :)
