Your Task: Use your classroom combined data to answer the questions below to share in how to save the world.

1. What were the biggest vampires you found?

For period 1, the biggest vampire was the rice cooker costing $11.35/month and producing over 60 lbs CO2/month. A distant second was the wifi router at $3.35/month and over 20 lbs CO2/month.

Period 2 had the Oceanic Cable Box as their biggest vampire, costing $4.02/month and producing 24.19 lbs CO2/month. This was followed by another brand of cable box and a wifi router, both costing over $3/month and producing over 18 lbs CO2/month.

2. How much money could your class save each month by unplugging vampires?

Period 1 could save over $900/month.

Period 2 could save over $490/month.

3. How much CO2 would be reduced if your class unplugged the vampires each month?

Period 1 could be reduced by 5,426 lbs/month.

Period 2 could be reduced by 2,901 lbs/month.

4. What was the most surprising thing you found while studying this standby power unit?

The most surprising thing found was the amount of waste (and the amount that could be saved) due to standby power, both in cost and in CO2 production. They were also surprised at the types of devices using the most standby power. The routers and cable boxes are not used during the day and night and could easily be controlled by using a power strip.
