2007: Old Lights were repaired with new bulbs plus a couple
ballasts.Repair cost $715.
•Expected bulb life ~ 3 Years.
•With new bulbs, they consumed 8227KWH ($1372) of electricity that year.
2008 to June 2010: Old Lights’ Bulb Performance
Declines
June 2010: Old Lights Replaced
with new LED
New LED, Savings ~$1168/Yr and 6765 Kwh/Yr with a projected life >15 years

Idling Quick Facts
•Idling gets ZERO miles per gallon
•2 minutes of idling = the fuel to drive a mile
•10 seconds of idling = the energy used to re-
start your car
•Restarting your car will only cost on
average $10/year in additional maintenance

Collecting ‘Baseline’ Data to meet the Town Plan
Excerpt from Dummerston Town Plan
“Dummerston will reduce total per-capita non-renewable energy consumption 40% by 2030 from a
2010 baseline.”
•To that end the Energy Committee has been collecting Energy data to establish the 2010 baseline.
• The slides that follow include some of that data which shows some interesting trends and comparisons.

Great Job, Dummerston!

Dummerston Energy Committee What’s Next?
a
Collecting ‘Baseline’ Data to meet the Town Plan
The Energy Committee is planning a survey to be sent out to Dummerston
Residents to collect more detailed data about their energy use, type of
fuels used, and more!
•Please take the time to fill it out and send it back.
•The data becomes knowledge.
•That knowledge will help us chart the Dummerston energy future.

Dummerston Energy CommitteeWhat’s Next?
a
Upgrading Street lights to LED
• Total anticipated fixture upgrades: 22
• Old fixtures: 100W Mercury Vapor (MV)• Now banned by federal law• 2200W x 12hrs/night= 9636 Kwh per year
• New Fixtures: 20-LED, 37W • Cost of Tariff is similar to MV Tarriff• 814W x 12hrs/night= 3565Kwh per year
• Annual energy savings: = 6070 KWH
• CO2 eliminated: 5631 pounds annually

School Gym Lighting Upgrade
• Total upgraded fixtures: 20
• Old fixtures: 400W Metal Halide = 8000W total
• New Fixtures: 4-lamp 54W fluorescent T-5 (216W each) = 4320 W
• Annual energy savings: 3.68 KW x 1760 Hours = 6477 KWH
• Cost Savings at $ 0.09 / KWH: 6477 x 0.09 = $583 / annually
• We expect the energy savings to be significantly more as the actual usage may be cut by a third to one-half of previous usage:
• The old lights took so long to turn on that it was impractical to turn them off during the day
• The new lights are controlled by motion sensors to automatically shut off when not needed
16
Dummerston Energy CommitteeWhats Next?
a
School Outdoor Lighting UpgradeCurrently the 30 fixtures around the school are older less efficient
technologies that are on ALL night, EVERY night.
They consume an estimated 10 Megawatt-hours per year, that’s nearly 5% of the total
school electricity!
The energy Committee is developing a plan to replace
them with LED lights controlled by motion sensors and/or timers.
Anticipated Annual Savings: 6 MWH or 5500 Lbs of CO2
$540/year
