Renewation is renewable resources electrification, this is, electrication using renewable energy (i.e. solar panels). -- 193.145.201.52 ( talk) 13:51, 16 September 2008 (UTC)
If there are other English language terms used in connection with the title or within the article that differ around the world, please feel free to list them here or to put in a translation in parentheses behind the word or phrase in question along with the country abbreviation.

This section is citation free- or relevant citation free. To talk about blind horses, then to give them a value in dollars without taking into account inflation or giving a comparison year and then propose using puppies. The economics of electricity is more dependant on the transmission costs than the generation costs. Electricity generation costs were dependant on the price of steaming coal which varied wildly according to the distance related transportation costs from the pits, and the child labour laws present in the country of origin. Just as later hydro power was used to generate electicity- waterwheel driven lineshafts were common and after the initial capital investment the energy was free. No mention of lighting, where comparison had to be made with on site gas retorts...
To me, in the industrial heartland of Lancashire the word electrification was only applied to two processes: Rural electrification in third world countries raised by Oxfam in the 1970s and to the Electrification processes on the railways which is not yet complete. It is fascinating as it involved experiment systems on DC and AC voltages chosen for their specific locations based on the financial calculations that I have eluded to above, and then their integration or not into a unified system. This included dual voltage locos, that could switch according to the supply available- as this was cheaper than setting a unified standard.
But back to the point. These folksy sentences even approach the topic in hand, and a lot more research needs to be done before anything is posted. Using a indepth case study of Rail electrification will allow the principles to be explored, and then the principles can be extended to cover local usage.
See [1] Basically According to the Power Law: P = I2 × R, that is power (in this case, power lost) is equal to current squared times resistance. To deliver power, it takes amps and volts. If you raise the volts, you can reduce the amps and still get the same power. If you reduce the amps, you lower the losses. Did you notice the squared term in the formula? That means if you reduce the current to one-tenth of the original value, your losses go down to one one-hundredth of what they were.
You calculate overall resistance as: length x the specific resistance of the specific cable [2]. For domestic 240V cable this is 18milliohm a meter. The specific resistance is approx. proportional to the cross-section area of the cable
There are some fun calculations to be done there. -- ClemRutter ( talk) 13:53, 13 May 2012 (UTC)
The wording of power loss was taken from Hunter. It is basically in agreement with the formula P=I^2R, with the exception that this formula is for DC and for AC we also have to consider power factor, which is minor. There is no need to involve wire size in the calculation; if we simply assume the same size wire and same length for both cases, we have the same resistance. Phmoreno ( talk) 01:57, 21 June 2012 (UTC)
May I strongly concur with ClemRutter's point. The article begins "Broadly speaking, electrification was the build out of the electrical generating and distribution systems which occurred in the United States, Britain and other countries from the mid-1880s ..." - but goes on later to state that "Swan's house, in Low Fell, Gateshead, was the world's first to have working light bulbs installed. The Lit & Phil Library in Newcastle, was the first public room lit by electric light,[12][13] and the Savoy Theatre was the first public building in the world lit entirely by electricity." and that the first public power station is believed to be that in Godalming, UK in 1881. One is unfortunately accustomed to the US bias in Wikipedia, but, in view of the fact that, in this case, the UK slightly beat the US to the punch, should not the introduction reflect this? A small point, perhaps, but in view of its claim to be an "encyclopedia" I do think a less Amero-centric view should be aimed for. EnglishBriarRose ( talk) 02:23, 23 June 2014 (UTC)
A specific claim like "first practical" can not be supported by a general Encyclopedia reference per WP:EXCEPTIONAL. Also the references right before and right after the claim contradict the claim. The more reliable source in the previous sentence shows four inventors (including Tesla) and claims none were an economical polyphase system. The more reliable source in the following sentence claims Tesla's motor was a "failure", far from a claim of "first practical". From what I can see (opinion here) Tesla had a very inclusive patent that invalidated other motor designs, that is not the same as the first practical motor.

Electrification of fossil fuel-based end uses, particularly in buildings and transportation, is a key strategy for climate mitigation. [1] [2] This section should be expanded to describe this strategy, or this discussion should be included in an additional article.
