Investing in Our Future Making a Difference,
One Light Bulb at a Time
Helping the planet . . .
Saving money . . .
with energy efficient light bulbs

Inspiration

• As a part of a unit on solar panels and renewable
  energy, we calculated the schools energy
  consumption in kilowatt hours.

• Seth, from VEEP, also came in and taught us
  about energy efficiency compact fluorescent
  light bulbs

3
This led us to investigate which lights in the
school are inefficient and consume a high amount
of energy.

• We now hope to change these inefficient lights
  so that we can reduce the cost of our energy use
  as well as our greenhouse gas emissions.

4
Gym Lights

• The gym lights that we currently use in both
  Crossett Brook and Thatcher Brook are
  inefficient metal halides which consume
• 452 Watts per fixture.

• We found that we can replace these lights with
  fluorescent lights that consume only 232 Watts
  per fixture.
• In addition, these lights would be installed with
  motion sensors to further reduce energy
  consumption.

5
Commons Area and Office Lights

• The commons area and office lights that we
  currently use at Crossett Brook are also metal
  halide sconces which consume 295 Watts per
  fixture.

• We found out that we could replace these lights
  with fluorescent lights that use only 111 Watts
  per fixture.

Pulling it All TogetherEnergy We Could Save
This graph shows the electric consumption of the
two gyms, the commons areas, and the office per
year. Energy consumption drops from 83,090kWh to
34,093kWh.

Pulling it all togetherMoney we could save

• This graph shows that by switching to more energy
  efficient lights, the school could save over
  6,000 dollars every year!

Savings Beyond our PocketsGreenhouse Gas
Emissions and our Planet

• According to Efficiency Vermont, for every kWh
  that CBMS does not consume, 1.3 pounds of CO2
  will not go into the atmosphere.

12
Why Should We Care?

• Atmospheric CO2 levels naturally fluctuate over
  time. However, current atmospheric CO2 levels are
  higher than anytime in the past 650,000 years.

13
How Does Carbon Dioxide Affect Earth?

14
Possible Effects of a Changing Climate

• A Loss of summer sea ice, melting glaciers, a
  rise in sea level

• A change in weather patterns, storm intensities
  and animal migration patterns.
• An increase in forest fires, heat waves, water
  shortages droughts

15
Making a Difference

• Replacing the gym, office and commons area lights
  
• will reduce CBMS emissions of carbon dioxide by
• 64,000 pounds every year!

16
Saving 64,000 pounds of CO2 in one year is
equivalent to

• Our CBMS solar panels working for 3 years or
• Moving almost 885 drivers from large SUVs to
  hybrids for ten years or,
• Protecting 244 acres of tropical rainforest from
  deforestation or,
• Replacing 122,000 refrigerators with the highest
  efficiency models.
