Topic: Energy, Food and Agriculture: Energy gradients in food production
Speaker: Dr. Charlie Hall
Time: July 9, 2025, at 13:30 Eastern Time (US and Canada)
Summary:
We are used to broad, seemingly homogonous agricultural fields, but in reality, yields vary enormously as a consequence of environmental conditions and crop genomes. In additional, yields are very much a function of use of fertilizers and other industrially derived inputs. About 20 percent of all U.S. energy use is used to produce, process, transport and prepare our food. How are these factors going to play out in the future?
