For SmartPlanet this week, I did another deep data dive to check the claim that improved vehicle efficiency has been largely responsible for the decline in U.S. oil consumption since 2005. My conclusion: Probably not. Read it here: Has vehicle efficiency really curbed U.S. oil demand?
An administrative note: My SmartPlanet column has been moved to a different section called The Take, under the Technology tab instead of the Energy tab. My older pieces there are still located under the Energy Futurist section. But you can find all of my SmartPlanet articles in both sections by searching by my name.
