Energy Use Benchmarking

Since 2011, the Town of Mamaroneck has taken numerous steps to reduce energy use and greenhouse gas emissions.  One of the benefits of those efforts is reduced costs. Initially, there were periodic efforts to measure energy and cost savings. In 2013, the Town engaged an outside company to help measure the reductions and savings.    Although those efforts were somewhat successful, this year, the Town has begun to use the NYSERDA ENERGY STAR Portfolio Manager program to track energy data and costs.

 The graphs below show energy data starting in 2014 and the significant reductions in energy use and greenhouse gas emissions as well as cost savings through 2020. It should be noted that 2020 was not a normal year for operations and the Town, as well as most other entities, experienced   significant decreases in energy use and associated costs. There are still significant improvements even if 2020 is removed from the data.

Total energy use includes: electricity, gas, gasoline and diesel for the Town Center, Fire Station, Hommocks Ice Rink, Senior Center, Highway Department, Street Lights and Fleet.

The Town plans to present current energy data on a semi-annual basis.


Examples of reductions from January 2014 to December 2019:

Total Energy Use:  Decreased 1,129,281 kBtu 

Total Greenhouse Gas Emissions:  Decreased 222.9 Metric Tons of CO2e

Total Costs:  Decreased $180,065

If including 2020, the decreases from January 2014 to December 2020 were significantly more:

  • Total Energy Use:  5,018,117 kBtu
  • Total Greenhouse Gas Emissions: 439.3 Metric Tons of CO2e
  • Total Costs: $319,174

Total Emissions Reductions of 439.3 Metric Tons of CO2e is equivalent to:

  • 49,432 gallons of gas avoided
  • 95 passenger vehicles taken off the road for a year
  • 7,264 tree seedlings grown for 10 year
