The table below shows simple comparison of electricity tariffs in industrialised countries and territories around the world, expressed in US dollars. The comparison does not take into account factors including fluctuating international exchange rates, a country's purchasing power, government electricity subsidies or retail discounts that are often available in deregulated electricity markets.[5]

Aside from times of natural disasters and large-scale accidents, electricity prices tend to be steadily dictated by electricity demand. Typically, the price of electricity rises when demand rises. In turn, the lower demand is, the cheaper electricity rates become. This pattern is due to the fact that increased demand requires increased energy production. When extra energy is demanded, utilities are forced to use alternative sources of energy production that may cost more to operate. For example, when electricity demand reaches a high point in Texas, coal plants are used alongside the typical natural gas plants. These coal plants are costlier and less effective than natural gas plants, but are necessary to meet high electricity demand levels.[1]
Electric bills for customers in the Houston area can more than double in summer months, mainly because air conditioning. Not coincidentally, electric rates also rise in the summer months because of this increase in demand. The most dramatic rate increases occur in month-to-month plans, but electric rates do increase across the board for all fixed-rate contract lengths.
Your most effective weapon, however, is a site like ComparePower (Power to Choose) to locate and compare details from various Houston electricity resellers.  In one fell swoop, you will efficiently and quickly locate and classify cheap electricity resellers all on one page, instead of wasting your valuable time searching out available companies and visiting their websites one by one (who even does that any more?).
The freedom to choose your energy rates in Maryland is not only available in homes but also to commercial customers. In fact, more than 90% of large businesses in the state have enrolled with alternative suppliers. This competition between energy suppliers to provide lower prices for businesses could be why commercial electric prices in Maryland are lower than the national average this year. If the same competition between suppliers existed for residential customers, prices might also decrease. However, without participation in energy choice, suppliers are not forced to compete for your business. Want to see the available rates? Enter your ZIP code above.
The problem is that across Africa, the vast majority of the power utilities are effectively bankrupt. Another World Bank study (pdf) on African Utilities shows that only two of the 39 African utilities surveyed, in the Seychelles and Uganda, were able to generate enough cash to cover both their operating costs and capital expenditures necessary to invest in the maintenance and expansion of the grid. In fact, only 19 of the 39 companies were able to generate enough cash to cover their day-to-day operating costs. It means the rest were not even able to pay everyday costs, like salaries, in full.

Technology that now allows smaller quantities of power to be generated closer to the end-users at prices not too much higher than grid-based power are undermining those economies of scale. More efficient turbines, for example, allow large power users like cement plants and petrochemical factories to come off the grid. Today the limiting factor for large companies to come off the grid often isn’t the efficiency of the power generation technology, but the lack of easy availability of fuel, such as gas or coal to power these turbines Even this problem is being solved by innovations like mini-liquefied natural gas projects.
Short-term prices are impacted the most by weather. Demand due to heating in the winter and cooling in the summer are the main drivers for seasonal price spikes.[121] In 2017, the United States is scheduled to add 13 GW of natural-gas fired generation to its capacity. Additional natural-gas fired capacity is driving down the price of electricity, and increasing demand.
