9 The next steps that the City can take to address its traffic and street lights’ electricity usage: - Identify the incandescent streetlights that have not been upgraded to more energy efficient fluorescents - Conduct a cost of implementation and payback period analysis for changing the City’s traffic signals from incandescent to LED. o LED Traffic signals consume 85% less energy than incandescent signals and on average have a payback period of less than seven years for a single signal. o There are significant maintenance and replacement lightbulb costs associated with incandescent signals whereas LED signals require nearly zero maintenance over their extended lifespan.

It is fair to assume that the average price of fuel will continue to fluctuate due to market influences that the City cannot control or predict.

When comparing 2004 to 2007, the Vehicle Fleet actually consumed 108 less gallons of gasoline and diesel. Despite this nearly equal consumption, the City spent over $46,000 more on fuel in 2007 than in 2004. With gas prices at $3.50 per gallon, the City’s Vehicle Fleet fuel cost would have been over $24,000 more in 2007.

The next steps that the City can take to address its Vehicle Fleet’s fuel consumption include: - Assign each City vehicle with its own credit card to allow for more accurate fuel consumption tracking. - Consolidate the City Vehicle Fleet under one administrative authority (not including emergency services and maintenance vehicles) in order to increase employee accountability and the accuracy of fuel consumption tracking
