An energy supplier is a company that provides electricity or gas to homes and businesses. They purchase energy from producers and then sell it to consumers. Energy suppliers play a crucial role in ensuring that customers have a reliable source of power for their daily needs. In many regions, consumers can choose their energy supplier, allowing them to compare prices and services. This competition can lead to better rates and options for customers. Some energy suppliers also offer renewable energy options, contributing to a more sustainable energy future by utilizing sources like solar energy and wind energy.
