Условие
Energy meters installed at your home have been measuring power usage for decades. Collect periodic readings for a sufficiently long period of time, e.g. last 20 years, and identify subtle or significant changes in energy using behavior at your home. When did your family switch from incandescent to fluorescent or LED bulbs? Is there a history of electric heating or air conditioning? Are there regular seasonal variations in power usage?
