Microactivism - why the image matters

Greenslowmovingvehicle is nothing more and nothing less than a decentralized conservation awareness group identified by magnets and stickers.  This tight visual medium can be perceived and "unpackaged" into a comprehensive political, environmental, social, and economic message - all while changing lanes or waiting for a green light.

The data.

We all flinch at each uptick of gas prices, right?  Well, factor in this rule of thumb: each 5 mph you drive over 60 mph is like paying an additional 20 cents per gallon for gas. 


EPA data: Gas Mileage vs. Speed


Speed = 40 MPH

Speed = 50 MPH

Speed = 60 MPH

Gas Mileage (mpg)

Gas Mileage (mpg)

Gas Mileage (mpg)






















The EPA is apparently quite confident that you wouldn't have any inclination to go as fast as 65, and of course no one ever exceeds the legal limit, so why waste time doing the numbers for 70, 75, or 80 mph?

If the sweet spot for fuel efficiency is in the 50's, as the chart indicate, then as you get into the high 60's and above, the addition of each mph requires more fuel than the last.  This is explained in greater detail at howstuffworks' article answering the question, "What speed should I drive to get maximum fuel efficiency?"

Which is more efficient, air conditioning or windows down?

People lead.

We have waited and waited, and continue to wait, for leadership on fossil fuel conservation.  At some point - NOW - it becomes clear that leadership is where leadership can be found.  If it can't be found in the government, do you point the finger, or do you act?  What if "acting" meant doing less? 

What if the act of doing less increased both your safety and the safety of your great great grandchildren?

Reducing your carbon footprint.

How about it?  Your speed is one of the main factors in determining how much oil it will take you from getting from one point to the next.  You are one of 6.6 billion human beings living on the earth.  So, what was the hurry again?
