It’s very important to do your own research to understand the business focus of the company you are considering, as well as tax advantages (and possible disadvantages) if the company is a limited partnership. For example, Seadrill Ltd. SDRL, -1.72%  provides offshore-drilling services worldwide. Seadrill Partners LLC SDLP, -3.22%  operates offshore-drilling rigs under specific contracts with several major oil companies, including Exxon Mobil Corp. XOM, +0.17%  and Chevron Corp. CVX, -0.43%  
July 2018 data, the latest available, show that the average U.S. price – 13.12 cents per kilowatt hour (kWh) – was down 0.7% compared with a year ago. If you live in Louisiana, you pay the lowest average residential electricity rates of any state in the country – 9.37 cents per kWh. The next lowest rate is in Washington, where residents pay an average of 9.79 cents per kWh.
OPEC nations, along with Russia and Mexico, have refused to cut production, which is their traditional tool to prop up oil prices, out of fear of losing market share to the U.S., which has transformed the international oil market by greatly expanding hydraulic fracturing over the past decade. And U.S. producers might not lower production as quickly as some investors expect because of the significant improvement in the efficiency of horizontal fracturing wells.
Technology also provides a long-term answer, even if it contributes to the problem in the short-term, as described earlier. As renewable power and storage technologies become cheaper and more efficient they will gradually allow for the implementation of cheaper mini-grids and smart grids, increasingly within the reach of the really poor, even in urban areas. Perhaps, grids will one day become marketplaces allowing people to sell excess power from their solar installations to those who have a need for power at that time. Prices can be set dynamically to allow supply to match demand.

Although electricity prices in the UK aren't cheap some countries have it much worse. In this article I'm going compare internationally to look at who is paying more $/kWh for their energy. I’ve gathered some numbers and crunched a little data to see who is really paying a lot for their power. For my neighbour here in the UK I’ll add a bit more data at the end.
Unlike with long-term plans, monthly, variable rate (no-contract) plans have no cancellation fees. You won’t have to pay a penalty if you decide to take your business elsewhere because you found a better deal. Plus, you won’t be left paying more than you should if the market rate for energy trends down. However, if the market prices rise, you’ll have to pay more than those who are in-contract.
