Electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electric current. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.
In electricity, charges produce electromagnetic fields which act on other charges. Electricity occurs due to several types of physics:
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure. Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation.
Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches and transformers.
Electric is the twelfth studio album by English synthpop duo Pet Shop Boys, released on 12 July 2013, and is their first album not to be released on Parlophone. It was released on the duo's own label, x2, through Kobalt Label Services.
In their native United Kingdom, Electric was BBC Radio 2's Album of the Week from 8 July 2013. It features a collaboration with British singer-songwriter/rapper Example.
Electric hit No. 3 and No. 26 in the UK and US respectively, their highest chart performances in both territories in 20 years. The album also performed very well in other markets. It was supported by the Electric Tour which visited 46 countries through 112 concerts.
Pet Shop Boys recorded the album in London, Berlin and Los Angeles from November 2012 to April 2013. On 30 April 2013, the duo announced on their website that they had recorded the album over the "last six months", with "Fluorescent" in particular "written and recorded within the last month". Stuart Price was chosen to produce the album. Price finished mixing the album in late April 2013.
Offshore may refer to:
Offshore (1979) is a novel by Penelope Fitzgerald. It won the Booker Prize for that year. It recalls her time spent on boats on the Thames in Battersea. The novel explores the liminality of people who do not belong to the land or the sea, but are somewhere in between. The epigraph, "che mena il vento, e che batte la pioggia, e che s'incontran con si aspre lingue" ("whom the wind drives, or whom the rain beats, or those who clash with such bitter tongues") comes from Canto XI of Dante's Inferno.
"Offshore", when used relative to hydrocarbons, refers to an oil, natural gas or condensate field that is under the sea, or to activities or operations carried out in relation to such a field. There are various types of platform used in the development of offshore oil and gas fields, and subsea facilities.
Offshore exploration is performed with floating drilling units.
