The article attributes this downward trend to:
- A 5% decline in residential electricity use in 2011 and 2012, despite the fact that more houses were being built and homes were actually getting larger. EIA attributes this decline to more efficient household appliances, better-insulated newer homes, and warmer winters.
- Office buildings becoming more efficient as efficiency standards for lighting and space heating go into effect.
- Industrial sector electricity use remaining below 2007 levels, reflecting a combination of economic and efficiency factors.
- Solar power and other forms of on-site generation possibly reducing utility sales.
