"We ended the fiscal year using 13,440 fewer gallons of fuel and driving 169,417 fewer miles. We were 6.8% under projection in our mileage budget which is about $194,000. Let's hope the trend continues into 13/14."Using the data from Pat's spreadsheet, I updated this graph, which shows the longer term trend beginning in the last quarter of 2004.
That's a pretty dramatic drop in fuel usage, in a City that has grown quite a bit geographically in the past decade. I've blogged on this topic previously, but to recap, the cause of the drop is a more fuel-efficient fleet, and less idling of vehicles. Gas is huge expense when you drive 2.3 million miles a year, and a 20% decrease in the average monthly fuel use over the past ten years represents a huge amount of taxpayers' dollars.
