Energy Demand in SchoolsUS 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

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

Energy StarProducts 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

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 Quality
Smog
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

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

In Summary…Energy production includes environmental and
human health costs.
