For the official domestic numbers, check out the EIA's Annual Energy Outlook.
In 2012, total domestic energy consumption was ~95 quadrillion BTUs.
- Energy Consumption By Sector and Source
- Residential Consumption
- Commercial Consumption
- Industrial Consumption
- Transportation Consumption
Food appears to take up about 16% of our total domestic energy usage.
A projection of food-related energy use based on 2007 total U.S. energy consumption and food expenditure data and the benchmark 2002 input-output accounts suggests that food-related energy use as a share of the national energy budget grew from 14.4 percent in 2002 to an estimated 15.7 percent in 2007.

Transportation appears to take up about 27% of our total domestic energy consumption.
