Many people are aware that Iceland has the cleanest energy in the world by far. The island-nation generates 100% of its electricity from renewables such as hydroelectric and geothermal sources, and it’s also flirting with wind power. What those same people might not realize, however, is that this results in some of the cheapest electricity in the world.
Depending on the state where you live, you’ll get your electricity bill from your local electric utility or your electricity provider.  Either way your electricity bill generally has two line items: supply and delivery. The supply charge is for the actual electricity used and this is paid to your electricity provider. The delivery charge is for the transmission and distribution of electricity and this is paid to your local electric utility.  In most states you will receive these charges on one bill, and the company that collects your payment will make sure that the appropriate parties are paid for their services.
How did we get this number?This total is calculated by taking the wattage and daily usage of your common appliances and converting this into a monthly kilowatt per hour (kWh) usage rate. To figure out the estimated cost based on this rate, multiply your kWh per month by the cost of your energy (an average rate is $.12 per kWh).

An additional bill was passed in 1999 that helped further establish a competitive electricity market by creating a price floor to prevent established energy providers from underselling emerging providers. In 2002, Texas finalized deregulation when the Public Utility Commission gave ERCOT the responsibility of managing and monitoring the Texas electricity market. The market opened up to around 6 million Texas power customers.

Consumers in Houston, Dallas, Fort Worth and Corpus Christi were promised bargains on electricity when the Texas Legislature deregulated the electricity market. But 16 years later they're still paying more for electricity than their counterparts in cities Texas lawmakers exempted from deregulation such as Austin and San Antonio, according to the Texas Coalition for Affordable Power which analyzed federal electricity pricing data.
In Texas' deregulated energy market, customers must pick their own electricity provider, all of which offer different rates per hour of power usage. You can shop for other power plans on the state-run website,, or try an alternative website, like to help find the cheapest plan. Keep in mind that many retail electricity contracts carry penalties for early termination.
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.

Switching electricity supplier could shave pounds off your bills. But it’s not always about how much hard cash you could save. You might be fed up with poor customer service, you might want greater visibility of your usage through an app or you might want to choose your supplier based on their green credentials, or whether they supply a smart meter.
