As you shop, you’ll see the rates advertised in terms of kilowatts per hour (kWh) — the energy used to power 1,000 watts for one hour. According to the U.S. Energy Information Administration, the average price per kWh for electricity in Pennsylvania is 14.52 cents, while the Public Utility Commission's “price to compare” currently hovers around 8.0 cents. Clearly, there’s a lot of price variety out there. And, given the hundreds of providers doing business in Pennsylvania, exploring electricity options can be pretty toilsome.
Ironically, technology can make the utilities’ problem worse, not better—at least in the short term. In the past, grids were developed because it was cheaper to generate large quantities of power and distribute it over wide distances, rather then generate smaller quantities closer to the place of use. It is for this reason that electricity is seen as a business that benefits from “economies of scale”.
uSwitch is a free service that handles the switching process for you. Once you've completed your energy switch, your new energy supplier will contact your old supplier and agree a switching date. You will then receive a welcome pack and letter from your new gas & electricity supplier. This will outline what you've agreed to, and tell you what happens next. There won't be any interruption in your gas and electricity supply.
One of the most common sticking points for electricity customers is what, exactly, the difference is between an electricity provider (also called REP, CRES, or electric supplier) and an electric utility (also called a TDSP, TDU, or EDU). They’re both vital to the success of electricity deregulation, but they play very different roles. Understanding how they fit together can make a big difference in your overall confidence as an electricity customer trying to shop for the best electricity plan.
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.
Foreign and emerging market investing involves special risks such as currency fluctuation and less public disclosure, as well as economic and political risk. Because the Global Resources Fund concentrates its investments in specific industries, the fund may be subject to greater risks and fluctuations than a portfolio representing a broader range of industries.

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.
