Know that Green Mountain’s cheapest advertised plans are all variable rate plans. “Pollution Free,” “Pollution Free Try 3,” or “SolarSPARC 10 Try 3” all advertise a great initial rate — a full cent below Pennsylvania’s 8.49 cent “price to compare” — but its variable rates means the company can raise them at any time. The two “Try 3” plans just lock in the low introductory rate for three months instead of one. The flipside of fixed rate: Should prices fall, you’ll be locked into a contract with a constant, elevated rate for two more months.
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.
Landsvirkun, Iceland’s national power company, offers electricity to buyers for as low as $0.043 per kWh, which is nearly on par with what can be found in Washington State. Coupled with 20% corporate tax, the nation’s low energy prices have attracted not just data centers, methanol producers, silicon metal producers but also aluminum companies—which, again, consume massive amounts of electricity.

The North Texas city of Wichita Falls is home to Midwestern State University, Sheppard Air Force Base, Lake Wichita and the power to choose. Texas residents who call the city home are able to shop for their electricity in Wichita Falls, meaning that they get to choose the energy plan they want from available retailers. Remember to explore all your options. If you need help deciding on an electric supply plan, call ChooseTexasPower.org.
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”.
Generation / supply price: What you pay. Unlike other states, Pennsylvania keeps cost per kWh easy to understand. Other states muddy the waters by including fees and discounts applied according to usage amounts in the quoted rate. PA companies show you you one steady rate. If you’re looking at a variable plan, this cost will reflect your first month only. If it is a special introductory rate, they’ll tell you how long it lasts.
Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
The consumer has the choice between buying from their local utility (Local Distribution Company - LDC) or from one of the deregulated suppliers. There is a large range of contract options from a variable price to 1,3 or 5 year fixed prices. Electricity provider switching is difficult once the consumer is in one of these contracts, unless they are close to the end of a fixed price contract. However, as of January 2010 there is a maximum termination penalty allowed.[2]
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.
