Let’s Get Energized Saving Energy At School Sites

Definitions of Energy  Einstein’s E = MC 2  Science texts - “Ability to do work” Next...

Electrical Power Generating Plant  Fossil fuels are burned to heat water.  The steam turns a turbine which creates the flow of electrons.  Cool water is used to condense the steam (60 to 70% lost energy). Next...

Electrical Terms  The electrical pressure = Volts (V)  The flow of the electrons = Amperage (amps)  The work produced = Watts Next...

What are the Watts  To calculate the watts multiply the amps by the voltage.  Watts = Volts x Amps  An electric pencil sharpener uses 2.4 amps. What are the watts?  Average voltage in United States is 120  2.4 amps x 120 volts = 288 Watts Next...

Electric Pencil Sharpener UL Label

Metrically Correct To convert Watts to Kilowatts - Divide by 1000 1200 Watts = ? kilowatts 1200 Watts ÷ 1000 = 12 kilowatts Next...

Time and Energy  Electrical energy consumption is measured using units of time called kilowatt-hours (kwh).  To calculate kwh multiply the wattage by hours.  Power companies bill by charging so many cents per kilowatt-hour. More later...

Environmental Impacts of Electrical Power  Land destruction from fuel extraction  Pollution or hazardous waste products  Thermal pollution from waste heat Next...

Annual Atmospheric Emissions From kwh of one Lee County Elementary School  Sulphur Dioxide11,855 lbs.  Oxides of Nitrogen14,644 lbs.  Particulate matter465 lbs.  Carbon Dioxide19,525,081 lbs.  Volatile Organic Compounds 697 lbs.  Water Consumption8,716,554 gallons So What?

Energy Consumption in United States 5% of world’s population 30% of world’s energy 16 million barrels of oil daily Next...

Years of Recoverable Reserves Remaining in the United States  Crude Oil23 years  Natural Gas68 years  Uranium364 years  Coal7,007 years  Renewablenot depletable We all live on an island... Next...

Lee County School District Utility Costs Propane 103,097gal\$ 66,108.90 Water & Sewer10,700,723kgal\$ 1,294,967.30 Electric112,677,294kwh\$ 7,688,321.00 Next...

School District Energy Totals Total Dollars per year \$7.69 million Total kwh per year 113 million Next...

Show Me the Watts...

Steps to Reducing Energy  Review your past energy use  Audit your current energy use  Find opportunities for reductions  Gather and share ideas  Commit and implement  Monitor and reward success Break…

Steps to Reducing Energy  Review your past energy use  Audit your current energy use Next…

Types of Audits  Heating, Ventilation, Air Conditioning (HVAC)  Lighting  Equipment and Machines Next...

Divide and Conquer  Studies show that including support staff increases chance of success by a factor 100.  Studies show that including students leads to increased test scores.

State Department of Education Goal 3 Standards  Information Managers  Effective Communicators  Numeric Problem Solvers  Creative and Critical Thinkers  Responsible Workers  Resource Managers  Systems Managers  Cooperative Workers  Effective Leaders Next...

Reducing Energy used for HVAC Systems On average, for every degree you lower your thermostat you raise cooling costs by 3%. Conversely, if you raise the thermostat one degree you can reduce cooling costs by 3%. Next...

Reducing Energy Used for Lighting Contrary to common belief, letting a light burn rather than turning it off never saves electrical energy. When electric lighting is not required, switch it off. Next...

Reducing Energy Used for Equipment and Machines “…there’s basically only one way to save energy used by your present office machines: turn them off when not needed.” Next...

Steps to Reducing Energy  Review your past energy use  Audit your current energy use  Find opportunities for reductions  Gather and share ideas  Commit and implement  Monitor and reward success Next…
