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...

4
Electrical Terms

• The electrical pressure Volts (V)
• The flow of the electrons Amperage (amps)
• The work produced Watts
• Next...

5
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

Metrically Correct

• To convert Watts to Kilowatts -
• Divide by 1000
• 1200 Watts ? kilowatts
• 1200 Watts 1000 12 kilowatts
• Next...

11
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.

• Land destruction from fuel extraction
• Pollution or hazardous waste products
• Thermal pollution from waste heat

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.

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.

29
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.

Reducing Energy Used for Equipment and Machines

• theres basically only one way to save energy
  used by your present office machines turn them
  off when not needed.
