Energy suppliers are companies that provide electricity and gas to homes and businesses. They purchase energy from various sources, such as power plants or natural gas fields, and then sell it to consumers. These suppliers play a crucial role in ensuring that energy is available when needed. In many regions, consumers can choose their energy supplier, allowing them to compare prices and services. Some suppliers offer renewable energy options, which come from sources like solar or wind power. This choice can help consumers support sustainable energy practices while potentially saving money on their energy bills.
