According to reports, a considerable plunge in the household sector energy usage has been noted in recent years. The significant decrease in the rate of pre-household energy consumption has been registered as well. Residential Energy Consumption Survey, an analysis by EIA conducted since the year 1980 showcases how introduction of improvements in renewable energy usage has reduced the energy intensity substantially to offset almost 70% of the overall growth both in terms of household and the size of the lodging.
According to the report, consumption of electricity across the households in the United States increased by a meager 0.3% from 9.3 quadrillion British Thermal Units (quads) in 1980 to 10.2 quads in 10.2. It was very impressive to see how the percentage of energy demand decreased substantially over the years. Factors such as structural changes in the American household sector, changes in energy intensity, and distribution of households attributed to the slackening growth in demand of conventional energy in the household sector. As per Annual Energy Outlook 2014 published by EIA, the intensity of per household energy demand will decrease by 16% between 2012 and 2040.
The Annual Energy Outlook 2014 reveals that growing preponderance of use of distributed generation has significantly reduced the percentage use of energy on per-American household basis. Despite of registering decrease in household energy consumption during the forecast period 2012 to 2040, electricity consumption will increase at the overall sectoral level owing to increase in the number of households. A major part of the growth of the sectoral consumption comes from growing market penetration of portable electrical devices, which doesn’t have much to offer in terms of energy efficiency. This rising demand for consumer electronics is also triggered by rising demand for air coolers as a significant number of US population shifts to warmer Southern region.
