Do We Have a Choice ?

• US school districts spend $6 billion each year on energy, second only to salaries1
1.5 billion of this, on average, is wasted due to energy inefficiency2
• A study of 851 schools found: From 2000 to 2001, when inflation
was 3.4 percent, per pupil expenditures for energy rose from $137 to $166 (22 percent)3
Energy Demand in Schools
The Influence of Small Changes…• A few days after a big blackout in 2003, the
University at Buffalo was quick to respond to an emergency request from the regional grid to cut back its electricity use.
• Maintenance personnel took steps to turn off equipment and lights that were not absolutely necessary.
IN 1 DAY, the savings amounted to:
$11,157.36
Changing Your School’s Energy Use• Top energy performing schools use 3X
less energy than the least efficient schools!
• First Steps:
Perform an Energy Survey or Audit Implement a Policy or Resolution Start with No Cost or Low Cost Options
Easy Solutions-No CostEnergy Item Action Savings
Lighting Turn lights off when not in use, and use daylighting
Up to 8-20% of lighting energy
Heating/Air Conditioning
Set thermostat as low as possible
For each degree, up to 5% savings
Heating, Ventilation and Air Conditioning
Limit after school activities to as few heating/cooling zones as possible
Up to 25% of heating/ cooling costs
Heating, Ventilation and Air Conditioning
Do not block air flow
to HVAC vents Up to 10% of heating/ cooling costs
Heating, Ventilation and Air Conditioning
Keep doors/windows closed while HVAC runs

Air Conditioning Install ENERGY STAR ®-labeled roofing material with high reflectance
Up to 10% of air conditioning energy usage Courtesy of PG&E
Energy Star• Products meet strict energy
efficiency standards set by US EPA and the US Department of Energy
• In 2005 the US saved enough energy to:
Avoid greenhouse gas emissions equivalent to those from 23 million cars
Saved $12 billion on utility bills Helped avoid 28,000 megawatts
(MW) of peak power
Demand Cleaner Energy!
• Contact your Board of Public Utilities to see if clean, local renewable energy sources are available
• Incorporate renewable energy into the power pool that serves your needs
Student Involvement
• Create signs to educate about saving energy
• Write articles in the school paper
• Research projects examining energy usage over time
• Contests between student groups
• Science projects dealing with energy

Publicize your success
Why Is Energy Conservation Important?• Energy production has negative
effects on the environment and human health

The Products of Fossil Fuel Use Greenhouse Gas
emissions increased 16% between 1990 and 20041, and carbon emissions are expected to grow 45% between 1990 and 20152
The Most Recent Data in 2003 Indicates…
• US Energy Sources released:
256.4 million metric tons of Methane
228 thousand metric tons of Nitrous Oxide
1021.1 million metric tons of Carbon Dioxide
142.4 million metric tons (carbon dioxide equivalent) of Hydrofluorocarbons, Perfluorocarbons, and Sulfur Hexafluoride
Health ConcernsAir QualitySmog NOx and SOx In the United States, about 2/3
of all sulfur dioxide and ¼ of all nitrogen oxide comes from electric power generation that relies on burning fossil fuels like coal

Why Do Greenhouse Gases Matter?

Why Do Greenhouse Gases Matter?• Historic link
between carbon dioxide concentration and temperature rise
What Does the World Look Like with Global Warming?• One study suggests that with minimal climate
warming,18% of the species studied would become extinct; with moderate climate warming, about 25% would become extinct; and with maximum warming, 35% would become extinct1
• The climate of Greenland may warm enough during the next few centuries to eventually eliminate the Greenland ice sheet, raising sea level by 7 meters (23 feet)2
• Sea ice cover in the Arctic is declining by 9 percent per decade3
• The number of Category 4 and 5 hurricanes has increased by 80 percent worldwide during the past 35 years4
Sea Ice 1979

“Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect.” ~Chief Seattle, 1855
