Agricultural Considerations

Farmers in Pennsylvania have historically had mixed feelings about DST. While the original justification for DST included giving farmers more daylight hours, modern farming practices rely heavily on the sun's position rather than clock time. Dairy farmers particularly note that cows don't adjust their biological clocks, creating temporary disruptions in milking schedules.

Energy Consumption Patterns in Pennsylvania

Recent studies on energy consumption during DST in Pennsylvania show modest savings of approximately 0.5% in electricity usage. However, these savings are offset by increased gasoline consumption as people take advantage of extended daylight for travel and recreation. The net energy impact remains a subject of ongoing research and debate among policy makers.
