Home Energy Audit – You can’t save energy until you know where you are using it

Trying to save energy (re: money) without knowing where you are using it is like assembling something without reading the instructions. Sometimes it works but most times it doesn’t.




Getting to the Bottom of Home Energy Use



In 1949, according to DOE’s Energy Information Administration (EIA), residential electricity consumption was 5% of total residential energy consumption. By 2009, it was 40%. This rise is attributable to many factors—appliance and equipment saturation, innovations in electronic technology, larger houses, and greater disposable income, among others. According to DOE, end-use electricity consumption will continue to grow as a percentage of total household energy consumption. As electricity consumption grows, so does base-load household electricity consumption—that year-round electrical load upon which seasonal electrical loads, like air-conditioning and space heating, are stacked. Water heating, refrigerators and freezers, lighting, laundry and kitchen appliances, electronics and entertainment devices, pumps, and miscellaneous plugged-in loads are common base-load end uses. All additional electricity use—from occasionally used devices, tools, or equipment; visitors; short-term construction jobs; and so on—is consumed on top of base-load use. And the fervent appetite for new and as-yet-unimagined appliances and electronic devices is expected to climb. Growth is why base-load end use is an important topic.
