04/22/2013 <br /> Figures 3 and 4 show the City's natural gas usage and cost with project estimates and presents <br /> another case for energy efficiency projects. Due to a pool closure, a number of energy efficiency <br /> projects, and a 25 percent drop in natural gas prices, the City's natural gas usage and cost <br /> dropped markedly between 2005 and 2010. Thus, a 15 percent energy reduction in half the <br /> existing facilities by 2020 could represent as much as a $93,823 reduction in annual natural gas <br /> costs from 2005, if natural gas were to remain at the 2010 price. <br /> Figure 3: Municipal Facilities Natural Gas Use (therms) with 2020 project estimate <br /> E <br /> i <br /> 180,000 <br /> 164,7 6 <br /> ;� 160,000 t erms <br /> ; � 140,000 <br /> E � 120,000 123,058 <br /> ` � 100,000 113 829 <br /> erm <br /> therms <br /> � 80,000 <br /> � 60,000 <br /> � �o <br /> ` � 40,000 <br /> � z 20,000 <br /> � 0 -�—�—�—. . f <br /> � 2005 2010 2015 2020 <br /> Year <br /> �__�_ � _ � <br /> Figure 4: Municipal Facilities Natural Gas Cost ($) with 2020 project estimate <br /> �---�v$250,000 ----- ��–�� <br /> ( <br /> � $200,000 196 269 <br /> � <br /> c°� $150,000 <br /> � <br /> �o <br /> � <br /> � � $100,000 , <br /> � � $102,446 <br /> '• Z $50,000 � <br /> I <br /> � $o � �� <br /> � 2005 2010 2015 2020 <br /> i <br /> Year <br /> i � <br /> i <br /> �. _�.., <br /> It is evident from the previous figures that the City is making good progress on municipal energy <br /> efficiency, but it is not certain if this pace of progress will be able to offset future energy costs. <br /> By committing to energy efficiency in public facilities, the City creates a hedge against rising <br /> energy costs, positions itself to take advantage of renewable energy opportunities, and also acts <br /> 7 <br /> RESO.#15258 <br /> MUFF#205 <br />
