The world's first public electricity supply was provided in late 1881, when the streets of the Surrey town of Godalming in the UK were lit with electric light. This system was powered from a water wheel on the River Wey, which drove a Siemens alternator that supplied a number of arc lamps within the town. This supply scheme also provided electricity to a number of shops and premises to light 34 incandescent Swan light bulbs.

Consumers in Houston, Dallas, Fort Worth and Corpus Christi were promised bargains on electricity when the Texas Legislature deregulated the electricity market.

It’s worth noting that you can switch for free with no exit fee 42-49 days before the end of your contract. Under Ofgem’s standards of conduct, energy firms have to give you between 42 and 49 days’ notice of your tariff ending. You can use this time to decide whether to stick with them, or switch. If you decide to switch, you won’t be charged an exit fee.

Of course, choosing a new electricity supplier or natural gas supplier does not mean you are replacing your utility. Your utility will still deliver whatever energy supply you choose, safely and reliably. Since your utility company depends on where you live, you don't have to worry about choosing a utility company. In general, utilities are responsible for maintaining the energy infrastructure. If you experience a power outage or see a downed power line, call your utility company. These are listed in the Utility Companies column below.
