Municipal Energy Savings

Between FY08 and FY12, the City invested $4.5 million in energy retrofits and building upgrades at 29 municipal and school facilities. These projects save an estimated 3 megawatt hours of electricity and over 73,000 therms of natural gas annually, and avoid $783,776 in energy costs and 1,916 tons of CO2e emissions annually. This is the equivalent to the emissions generated by the energy use of 89 average American homes. Multi-year efficiency projects totaling $6.9 million which began in FY13 are expected to save an additional 6,900 MMBtu annually.

The graphs below (pdf) illustrate the energy costs and use avoided by the City's implementation of energy conservation measures over the past five years.

Avoided Municipal Energy Use

Without these energy saving initiatives, the City would have spent an additional $1.6 million in utility cost, and used almost 34,000 MMBtu more energy, releasing an additional 7.4 million pounds of greenhouse gas emissions.
