Efficiency in the Home

I can identify the forms of energy inputs and outputs in a device or system

I understand how to determine the number of watts used by a device using the formula P=IV

I understand how to determine the total amount of energy consumed using the formula E=Pt

I understand the laws of conservation of energy and that all energy conversions have waste energy

I can calculate its efficiency

I can investigate and describe techniques for reducing waste of energy in common household devices
