The mid to late 1880s saw the introduction of alternating current (AC) systems in Europe and the U.S. AC power had an advantage in that transformers, installed at power stations, could be used to raise the voltage from the generators, and transformers at local substations could reduce voltage to supply loads. Increasing the voltage reduced the current in the transmission and distribution lines and hence the size of conductors and distribution losses. This made it more economical to distribute power over long distances. Generators (such as hydroelectric sites) could be located far from the loads. AC and DC competed for a while, during a period called the War of Currents. The DC system was able to claim slightly greater safety, but this difference was not great enough to overwhelm the enormous technical and economic advantages of alternating current which eventually won out.

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.
FirstEnergy’s online shopping experience is woefully outdated, which makes it harder than usual to get to the fine print. You’ll need to take the first step of signing up — follow the Enroll Now! Link — to get “Terms and Conditions” to appear. The website also pays the typical lip service to the green movement, but FirstEnergy plants generate over 95 percent of the company’s total electricity from conventional fuels.
Another unwelcome side effect of not knowing your average monthly kWh usage level is that you may end up paying more than you expect. This can occur when a customer inadvertently shops an electric rate based on a higher usage level than they actually use. Electricity suppliers commonly advertise their electric rates associated with the highest (2000 kWh) usage levels since those tend to be the lowest rates.
