Energy suppliers are companies that provide electricity and gas to homes and businesses. They purchase energy from various sources, such as power plants and 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 for competition and potentially lower prices. Some suppliers also offer renewable energy options, such as solar or wind power, to help reduce environmental impact. This choice empowers consumers to select suppliers that align with their values and energy needs.
