Reducing energy use saves natural resources and can save your school money. The Energy Investigation will help you find out what uses the most energy at your school and ways that energy is wasted. It will help you find ways to save energy to make your school more environmentally friendly and sustainable. Sustainable practices are those which meet the needs of the present without compromising the ability of future generations to meet their needs.

How much electricity does a toaster use? How about a T.V. or a cell phone charger? Investigation how much electricity an item uses, whether it's on or off, can help us make better decisions and save energy. 

Phantom Load
Time to Investigate
To investigate how much energy is being used by items in your school, choose 5 items and put them in standby mode, plug them into a power strip, and t...
• A phantom load is the amount of energy a device consumes while in standby or sleep mode, or while turned off.
• The off button on many appliances may not really mean off; instead, it means standby. For example, appliances with remote controls or internal clocks—such as TVs, DVDs, and microwave ovens—have phantom loads. Other appliances with phantom loads include computers, printers, and plug-in battery chargers such as those for cell phones, iPods, and cameras.
• Use of a power strip can minimize the phantom energy load loss. Plug all components of a computer, TV, and so forth into the power strip. Turn off the power strip with a single switch. Anything plugged into the strip now is truly turned off.
• You can also unplug appliances when not in use.
