Washington (Platts) — The US House of Representatives Energy and Commerce Committee, in a 34-17 vote along party lines, approved energy provisions in the $825-billion economic recovery package that include $11 billion in smart grid investments and policies to encourage states to adopt utility rate structures that ensure their cost recovery.

Fuel consumption vs. miles per gallon

A jump from 14 to 16 mpg saves as much oil as a jump from 35 to 51 mpg, a NY Times editorial emphasized today. You may be tempted to do the math yourself just to prove it…

The reasoning is illustrated in the graph below of annual fuel consumption based on 12,000 vehicle miles. Fuel consumption is a non-linear function of miles per gallon, making it somewhat difficult to compare annual fuel costs of different vehicle types. Fuel consumption per mile or per 100 miles traveled, might be a better yardstick. But then again, this is not rocket science.
