Consider a normal day - wake up in a heated (or air conditioned) house, turn on the lights, plug in the coffee maker, make sure that your laptop and smartphone are charged, drive to work, enter an office with computer, printer, lighting, and heat (or AC) - the list could go on nearly endlessly.
How can be gain some clearer information about the different ways energy is used?
The US Energy Information Administration (EIA) classifies energy based on its end use. In 2011 the industrial sector accounted for 31 percent of all energy used in the US. The transportation sector accounted for 28 percent, the residential sector 22 percent, and the commercial sector accounted for 19 percent of usage.
While the transportation, residential, and commercial sectors have experienced consistent increases in consumption of energy, usage in the industrial sector has been relative flat since the early 1970s as the economy has been less dependent on manufacturing and as the sector has used energy more efficiently.
