Why Should You Care about Energy Use?

It saves money
• Using less energy means lowering utility bills and saving
  money
It reduces carbon emissions
• Carbon emissions are linked to climate change that
  results in more common severe weather events
  (hurricanes, heavy rains/floods, and droughts)

Reading an Electricity or Natural Gas Bill
Reading an Electricity or Natural Gas Bill

• There are different units of measurement for energy,
  depending on the form of energy
• Electricity is measured in kilowatt hours (kWh)
• Natural Gas, (used for heating, hot water, cooking, and
  sometimes clothes dryers) is measured in Therms
• 1 therm = 29.3 kWh

Ways to Save Energy

Heating and Cooling
• If possible, avoid space heaters
  as they are very inefficient and
  become a fire hazard if
  something is placed on them
• Buy Energy Star air conditioner

Why You Shouldn’t Open Windows in Winter

                                                The Stack Effect

                                                1) Window is opened in
                                                   an upper floor unit

                                                2) Heat rushes out and
                                                   draws warm air up
                                                   from other units

                                                3) Cold air is drawn
                                                   from the outside to
                                                   replace air

Ways To Save Energy

Appliances:
• Look out for Phantom
  loads – little lights, LCD
  displays, and other
  indicators that remain ON
  even if your electronics
  are OFF
• Turn off computer
  when not in use
  (not just sleep…OFF)
• Use a timer or smart
  surge protector

How a Smart Strip Surge Protector Works

Smart strips sense when a master appliance is
turned off and switches peripherals off
When the master electronics are:
• Turned ON, all peripherals are turned ON
• Turned OFF, the peripherals are turned OFF




Control Outlet: Plug your independent          Dependant Outlets: Plug
“Master” electronics here                      your peripherals in here

Timer strips allow residents to set times of the
day to turn the outlets ON or OFF




Timer Switch: Set the time of day              Timed Outlets: Outlets switched
to switch outlets ON and OFF                   ON/OFF depending on timer setting

Ways to Save Energy

Water:
• Install an efficient showerhead
  (<2 gallons/minute)
• Less heated water down the
  drain saves energy
• Set clothes washers to use only
  cold water

Ways to Save Energy

Lighting:
• Replace incandescent
  lighting with compact
  fluorescent (CFL)
• CFLs use 66% less energy
  than incandescents
• Turn lights off when not
  in use
