National Energy Shopping Day is observed on June 21 and serves as a reminder for consumers to review their energy expenses, which often go unchecked. Founded by the Retail Energy Supply Association (RESA), the day encourages households and businesses to compare electricity and natural gas suppliers to find plans that better fit their budgets and preferences. Participants are urged to examine their energy bills closely, understand the differences between supply and delivery charges, and gather relevant details before comparing rates from multiple providers. The event promotes informed decision-making by emphasizing the importance of asking questions about contract terms, fees, and service features. Additionally, sharing knowledge and experiences with neighbors and friends is encouraged to foster a culture of energy literacy and competition among suppliers, ultimately leading to better pricing and service.
