To put this figure into perspective – 350 million barrels of oil is the equivalent of:
- about 2% of total annual energy consumption in the United States
- about 20% of the nation’s net energy imports
- twice the amount of energy that Switzerland (with its more than 8 million people) consumes in an entire year
In their study, UT Austin Professor Michael E. Webber and his former graduate student, Amanda Cuellar, estimated the energy that is embedded in wasted food in the United States. In other words, they calculated how much energy was used to get food to our tables, which is wasted when that food ends up in the garbage bin. Their process involved calculating the energy intensity of the food production supply chain including the following steps for different types of food:
- agriculture (i.e. growing/raising food)
- transportation (i.e. moving food from field to processing plants)
- food sales

In the week after Thanksgiving, Americans will throw away almost 200 million pounds of turkey according to the Natural Resource Defense Council. If you want to save some money (and energy), explore some ways to use those leftovers (for those who like to cook, NPR has some ideas).
