'''Orkney''' ({{IPAc-en|ˈ|ɔr|k|n|i}}), also known as the '''Orkney Islands''', is an [[archipelago]] off the north coast of mainland [[Scotland]]. The plural name '''the Orkneys''' is also sometimes used, but locals now consider it outdated. Part of the [[Northern Isles]] along with [[Shetland]], Orkney is 10 miles (16&nbsp;km) north of [[Caithness]] and has about 70 islands, of which 20 are inhabited.<ref name=HS>Haswell-Smith (2004) pp. 336–403.</ref><ref>Wickham-Jones (2007) p. 1 states there are 67 islands.</ref><ref name=NRS>{{NRS1C}}</ref> The largest island, the [[Mainland, Orkney|Mainland]], has an area of {{convert|523|km2}}, making it the [[List of islands of Scotland|sixth-largest Scottish island]] and the [[List of islands of the British Isles|tenth-largest island in the British Isles]].<ref>Haswell-Smith (2004) pp. 334, 502.</ref> Orkney's largest settlement, and also its administrative centre, is [[Kirkwall]].<ref>Lamb, Raymond "Kirkwall" in Omand (2003) p. 184.</ref>

Orkney is one of the 32 [[Subdivisions of Scotland|council areas]] of Scotland, as well as a [[Orkney (Scottish Parliament constituency)|constituency]] of the [[Scottish Parliament]], a [[Lieutenancy areas of Scotland|lieutenancy area]], and an [[counties of Scotland|historic county]]. The local council is [[Orkney Islands Council]].

The islands have been inhabited for at least {{formatnum:8500}} years, originally occupied by [[Mesolithic]] and [[Neolithic]] tribes and then by the [[Picts]]. Orkney was colonised and later annexed by the [[Kingdom of Norway]] in 875 and settled by the [[Norsemen]]. In 1472, the [[Parliament of Scotland]] absorbed the [[Earldom of Orkney]] into the [[Kingdom of Scotland]], following failure to pay a [[dowry]] promised to [[James III of Scotland]] by the family of his bride, [[Margaret of Denmark, Queen of Scotland|Margaret of Denmark]].<ref>Thompson (2008) p. 220.</ref>

In addition to the Mainland, most of the remaining islands are divided into two groups: the North Isles and the South Isles. The [[#Climate|local climate]] is relatively mild and the soils are extremely fertile; most of the land is farmed, and agriculture is the most important sector of the economy. The significant wind and marine energy resources are of growing importance; the amount of electricity that Orkney generates annually from renewable energy sources exceeds its demand. Temperatures average {{convert|4|C|F}} in winter and {{convert|12|C|F}} in summer.

The local people are known as Orcadians; they speak a distinctive [[Orcadian dialect|dialect]] of the [[Insular Scots|Scots language]] and have a rich body of folklore. Orkney contains some of the oldest and best-preserved Neolithic sites in Europe; the "[[Heart of Neolithic Orkney]]" is a designated [[UNESCO]] [[World Heritage Site]]. Orkney also has an abundance of marine and avian wildlife.

Both Orkney and [[Shetland]] saw a significant influx of Norwegian settlers during the late 8th and early 9th centuries.

The history of Orkney prior to this time is largely the history of the ruling aristocracy. From then on ordinary people emerge with greater clarity. An influx of Scottish entrepreneurs helped to create a diverse and independent community that included farmers, fishermen and merchants that called themselves ''comunitas Orcadie'' and who proved themselves increasingly able to defend their rights against their feudal overlords.<ref>Thompson (2008) p. 183.</ref><ref>Crawford, Barbara E. "Orkney in the Middle Ages" in Omand (2003) pp. 78–79.</ref>

From at least the 16th century, boats from mainland Scotland and the Netherlands dominated the local [[herring]] fishery. There is little evidence of an Orcadian fleet until the 19th century, but it grew rapidly, and 700 boats were involved by the 1840s with Stronsay and later [[Stromness]] becoming leading centres of development. [[Whitefish (fisheries term)|White fish]] never became as dominant as in other Scottish ports.<ref name=Coull/>

Agricultural improvements beginning in the 17th century resulted in the enclosure of the commons and ultimately in the Victorian era the emergence of large and well-managed farms using a five-shift rotation system and producing high-quality beef cattle.<ref>Thomson, William P.L. "Agricultural Improvement" in Omand (2003) pp. 93, 99.</ref>

In the 17th century, Orcadians formed the overwhelming majority of employees of the [[Hudson's Bay Company]] in Canada. The harsh winter weather of Orkney and the Orcadian reputation for sobriety and their boat handling skills made them ideal candidates for the rigours of the Canadian north.<ref>Thompson (2008) pp. 371–72.</ref> During this period, burning [[kelp]] briefly became a mainstay of the islands' economy. For example, on Shapinsay over {{convert|3000|LT|tonnes|0|lk=on}} of burned seaweed were produced per annum to make [[soda ash]], bringing in £20,000 to the local economy.<ref>Haswell-Smith (2004) pp. 364–65.</ref> The industry collapsed suddenly in 1830 after the removal of tariffs on imported [[alkali]].<ref>Thomson, William P.L.

During the 18th century [[Jacobite risings]], Orkney was largely Jacobite in its sympathies. At the end of the 1715 rebellion, a large number of Jacobites who had fled north from mainland Scotland sought refuge in Orkney and were helped on to safety in Sweden.<ref>Baynes (1970) p. 182</ref> In 1745, the Jacobite lairds on the islands ensured that Orkney remained pro-Jacobite in outlook and was a safe place to land supplies from Spain to aid their cause. Orkney was the last place in the British Isles that held out for the Jacobites and was not retaken by the [[Broad Bottom Ministry|British Government]] until 24 May 1746, over a month after the defeat of the main Jacobite army at [[Battle of Culloden|Culloden]].<ref>Duffy (2003) pp. 464–465, 528, 533–534, 550</ref>

Orkney was the site of a [[Royal Navy]] base at [[Scapa Flow]], which played a major role in [[World War I]] and [[World War II]]. After the [[Armistice]] in 1918, the [[German High Seas Fleet]] was transferred in its entirety to Scapa Flow to await a decision on its future. [[Scuttling of the German fleet at Scapa Flow|The German sailors opened the seacocks and scuttled all the ships]]. Most ships were salvaged, but the remaining wrecks are now a favoured haunt of recreational divers. One month into World War II, a German [[U-boat]] sank the Royal Navy battleship {{HMS|Royal Oak|08|6}} in Scapa Flow. As a result, [[Churchill Barriers|barriers]] were built to close most of the access channels; these had the additional advantage of creating causeways enabling travellers to go from island to island by road instead of being obliged to rely on ferries. The causeways were constructed by Italian prisoners of war, who also constructed the ornate [[Italian Chapel]].<ref name=Thom434>Thompson (2008) pp. 434–36.</ref>

The navy base became run down after the war, eventually closing in 1957. The problem of a declining population was significant in the post-war years, though in the last decades of the 20th century, there was a recovery and life in Orkney focused on growing prosperity and the emergence of a relatively classless society.<ref>Thompson (2008) pp. 439–43.</ref> Orkney was rated as the best place to live in Scotland in both 2013 and 2014, and in 2019 the best place to live in the UK, according to the Halifax Quality of Life survey.<ref>{{cite web |last=Harrison |first=Jody |date=20 December 2014 |url=http://www.heraldscotland.com/news/home-news/orkney-best-for-quality-of-life.114929765 |title=Orkney best for quality of life |archive-url=https://web.archive.org/web/20211027204334/https://www.heraldscotland.com/news/13194276.orkney-best-quality-life/ |archive-date=27 October 2021 |location=Glasgow |work=The Herald |access-date=20 December 2014}}</ref><ref>{{cite web |url=https://news.sky.com/story/orkney-crowned-best-place-to-live-in-the-uk-in-halifax-quality-of-life-survey-11618040 |archive-url=https://web.archive.org/web/20190528110803/https://news.sky.com/story/orkney-crowned-best-place-to-live-in-the-uk-in-halifax-quality-of-life-survey-11618040 |title=Orkney crowned best place to live in the UK in Halifax quality of life survey |archive-date=28 May 2019 |work=Sky News |access-date=28 May 2019}}</ref>

In the modern era, the population peaked in the mid-19th century at just over 32,000 and declined for a century thereafter to a low of fewer than 18,000 in the 1970s.

The islands are mainly low-lying except for some sharply rising sandstone hills on Mainland, Rousay and Hoy (where the tallest point in Orkney, [[Ward Hill, Hoy|Ward Hill]], can be found) and rugged cliffs on some western coasts. Nearly all of the islands have [[loch]]s, but the watercourses are merely streams draining the high land. The coastlines are indented, and the islands themselves are divided from each other by straits generally called "sounds" or "firths".{{sfn|Chisholm|1911|p=279}}<ref name=OS/><ref name="Brown 2003 p. 19">Brown, John Flett "Geology and Landscape" in Omand (2003) p. 19.</ref>

{{Main|Geology of Orkney}}

[[File:OrkneyGeologyMap.png|thumb|left|alt=A map of the geology of Orkney. Hoy to the southwest is predominantly formed from Hoy/Eday Sandstones. The Mainland at centre is largely Stromness flagstones with Rousay flagstones to the east. The North and South Isles are a mixture of Eday and Rousay sandstones.|Geology of Orkney]]

The superficial rock of Orkney is almost entirely [[Old Red Sandstone]], mostly of Middle [[Devonian]] age.<ref name="Millennium">Marshall, J.E.A., & Hewett, A.J. "Devonian" in Evans, D., Graham C., Armour, A., & Bathurst, P. (eds) (2003) ''The Millennium Atlas: petroleum geology of the central and northern North Sea''.</ref> As in the neighbouring mainland county of [[Caithness]], this sandstone rests upon the [[metamorphic rock|metamorphic]] and igneous rocks of the [[Moine Supergroup|Moine]] series, as may be seen on the Mainland, where a narrow strip is exposed between Stromness and Inganess, and again in the small island of [[Graemsay]]; they are represented by grey [[gneiss]] and [[granite]].{{sfn|Chisholm|1911|p=279}}<ref>Hall, Adrian and Brown, John (September 2005) [http://www.landforms.eu/orkney/Geology/Basement/basement.htm "Basement Geology"] {{Webarchive|url=https://web.archive.org/web/20160303193431/http://www.landforms.eu/orkney/Geology/Basement/basement.htm |date=3 March 2016 }}. Retrieved 10 November 2008.</ref>

The Middle Devonian is divided into three main groups. The lower part of the sequence, mostly [[Eifelian]] in age, is dominated by lacustrine beds of the lower and upper Stromness Flagstones that were deposited in [[Orcadian Basin|Lake Orcadie]].<ref>Hall, Adrian and Brown, John (September 2005) [http://www.landforms.eu/orkney/Geology/Stratigraphy/Devonian%20Lower%20Middle.htm "Lower Middle Devonian"] {{Webarchive|url=https://web.archive.org/web/20120121054128/http://www.landforms.eu/orkney/Geology/Stratigraphy/Devonian%20Lower%20Middle.htm |date=21 January 2012 }}.

[[File:OldManofHoycloseJM.jpg|thumb|right|upright|alt=A tall perpendicular stack of brown rock stands in the sunlight in front of a shore with high cliffs that lie in the shadows.|The [[Old Man of Hoy]]]]

The Old Man of Hoy is formed from sandstone of the uppermost [[Eday Group]] that is up to {{convert|800|m|ft}} thick in places. It lies [[Unconformity|unconformably]] upon steeply inclined flagstones, the interpretation of which is a matter of continuing debate.<ref name=Brown/><ref>Mykura, W.

The Devonian and older rocks of Orkney are cut by a series of WSW–ENE to N–S trending faults, many of which were active during deposition of the Devonian sequences.<ref>Land Use Consultants (1998) [http://www.snh.org.uk/publications/on-line/LCA/orkney.pdf "Orkney landscape character assessment"] {{Webarchive|url=https://web.archive.org/web/20160303212540/http://www.snh.org.uk/publications/on-line/LCA/orkney.pdf |date=3 March 2016 }}.

Middle Devonian [[basalt]]ic [[volcanic rock]]s are found on western Hoy, on Deerness in eastern Mainland and on Shapinsay.

[[Glacial striation]] and the presence of [[chalk]] and [[flint]] [[Glacial erratic|erratics]] that originated from the bed of the North Sea demonstrate the influence of ice action on the [[geomorphology]] of the islands.

===Climate===
[[File:Aerial image of Sands of Evie, a beach near Stenso, Mainland, Orkney.jpg|thumb|Aerial image of [[Sands of Evie]], a beach near Stenso, Mainland]]
Orkney has a cool temperate climate that is remarkably mild and steady for such a northerly [[latitude]], due to the influence of the warm waters of the [[Norwegian Current]], a north-easterly extension of the [[North Atlantic Drift]] which is itself an extension of the [[Gulf Stream]].<ref>Chalmers, Jim "Agriculture in Orkney Today" in Omand (2003) p. 129.</ref> The average temperature for the year is {{convert|8|°C|°F|abbr=on}}; for winter {{convert|4|°C|°F|abbr=on}} and for summer {{convert|12|°C|°F|abbr=on}}.<ref name=met>[http://www.metoffice.gov.uk/climate/uk/averages/regmapavge.html "Regional mapped climate averages"] {{Webarchive|url=https://archive.today/20120804165705/http://www.metoffice.gov.uk/climate/uk/averages/regmapavge.html |date=4 August 2012 }} [[Met Office]].

The average annual rainfall varies from {{convert|850|mm|in}} to {{convert|1060|mm|in}}.<ref name=met/> Winds are a key feature of the climate and even in summer there are almost constant breezes. In winter, there are frequent strong winds, with an average of 52 hours of gales being recorded annually.<ref>[http://www.orkneyjar.com/orkney/climate.htm "The Climate of Orkney"] {{Webarchive|url=https://web.archive.org/web/20090402052831/http://www.orkneyjar.com/orkney/climate.htm |date=2 April 2009 }} Orkneyjar.

===Administrative history===
On its absorption into Scotland in 1472, the landholdings and jurisdictions of the old earldom of Orkney passed to the Scottish crown. The separate lordship of Shetland was absorbed into Scotland at the same time.<ref name=Crawford/> More typically Scottish forms of administration were gradually introduced to the Northern Isles. The position of [[Sheriff of Orkney and Shetland]] was created in 1541.<ref>{{cite web |last1=Anderson |first1=Peter |title=Earl William to Earl Patrick: A Survey of the History of Orkney and Shetland from 1468 to 1615 |url=https://www.ssns.org.uk/wp-content/uploads/2019/10/13_Anderson_ShetlandNL_1996_pp_174-185.pdf |website=Scottish Society for Northern Studies |page=178 |date=1996}}</ref> Orkney and Shetland retained their own legal systems until 1612, when the general laws of Scotland were applied.<ref>{{cite book |last1=Moodie Heddle |first1=J.

[[Commissioners of Supply]] were established in 1667 for each shire across Scotland. Unusually, despite being one [[Shires of Scotland|shire]], Orkney and Shetland were given separate bodies of commissioners.<ref>{{cite web |last1=Brown |first1=Keith |title=Act of the convention of estates of the kingdom of Scotland etc. for a new and voluntary offer to his majesty of £72,000 monthly for the space of twelve months, 23 January 1667 |url=http://www.rps.ac.uk/trans/1667/1/10 |website=Records of the Parliament of Scotland |publisher=University of St Andrews |access-date=25 February 2023}}</ref><ref>{{cite book |title=Journals of the House of Commons |date=1809 |publisher=His Majesty's Stationery Office |location=London |pages=49–50 |url=https://books.google.com/books?id=aRlDAAAAcAAJ&dq=%22orkney%20and%20zetland%22%20%22commissioners%20of%20supply%22&pg=PA50 |access-date=8 October 2024}}</ref> More local government functions were gradually given to the commissioners over time.<ref>{{cite web |title=Scottish Counties and Parishes: their history and boundaries on maps |url=https://maps.nls.uk/geo/boundaries/history.html |website=National Library of Scotland |access-date=2 September 2024}}</ref> At a court case in 1829, the [[Court of Session]] declined to rule on whether Orkney and Shetland were one county or two.

Local government was reformed in 1975 under the [[Local Government (Scotland) Act 1973]], which replaced Scotland's counties, [[burgh]]s and [[landward district]]s. In most of Scotland a two-tier structure of upper-tier regions and lower-tier districts was used, but a single-tier structure of [[Islands council areas of Scotland|island areas]] was used for Orkney, Shetland and the [[Western Isles]].<ref name=1973act>{{cite legislation UK|type=act|act=Local Government (Scotland) Act 1973|year=1973|chapter=65|accessdate=17 April 2023}}</ref> Further local government reform in 1996 introduced single-tier council areas across all of Scotland.

Parishes existed from medieval times. From 1845 to 1894 they had parish boards and from 1894 to 1930 they had parish councils.

===Community councils===
[[List of community council areas in Scotland|Community councils]] were created in 1975 as part of the wider reforms that year. They have no statutory powers, but serve as a representative body for their communities. Orkney Islands Council designates community council areas, but a community council is only formed if there is sufficient interest from the residents.

==Islands==
{{Main|List of Orkney islands}}

===The Mainland===
{{Main|Mainland, Orkney}}
[[File:Stromness 2.jpg|thumb|alt=Stone houses crowd around a shore, the gable ends facing the water, with green hills beyond.|[[Stromness]] on the Mainland is the second-largest settlement in Orkney.]]

The Mainland is the largest island of Orkney. Both of Orkney's [[burgh]]s, [[Kirkwall]] and [[Stromness]], are on this island, which is also the heart of Orkney's transport system, with [[ferry]] and air connections to the other islands and to the outside world. The island is more heavily populated (75% of Orkney's population) than the other islands and has much fertile [[Farmland (farming)|farmland]]. The Mainland is split into areas called East and West Mainland. These areas are determined by whether they lie east or west of Kirkwall. The bulk of the mainland lies west of Kirkwall, with comparatively little land east of Kirkwall.<ref>Haswell-Smith (2004) pp. 354–363.</ref><ref name=OS/>
West Mainland parishes are:
[[Stromness (parish)|Stromness]], Sandwick, Birsay, Harray, Stenness, Orphir, Evie, Rendall and Firth.
East Mainland Parishes are:
St Ola, Tankerness, St Andrews, Holm and Deerness.<ref name=NLS/>

The island is mostly low-lying (especially East Mainland) but with coastal cliffs to the north and west and two sizeable lochs: the [[Loch of Harray]] and the [[Loch of Stenness]]. The Mainland contains the remnants of numerous [[Neolithic]], [[Picts|Pictish]] and [[Viking]] constructions.<ref name=OS/> Four of the main Neolithic sites are included in the [[Heart of Neolithic Orkney]] [[World Heritage Site]], inscribed in 1999.<ref>[https://whc.unesco.org/en/list/514bis "Heart of Neolithic Orkney".] UNESCO. Retrieved 18 May 2025.</ref>

The other islands in the group are classified as north or south of the Mainland. Exceptions are the remote islets of [[Sule Skerry]] and [[Sule Stack]], which lie {{convert|60|km|mi|0}} west of the archipelago, but form part of Orkney for local government purposes.<ref name=OS/> In island names, the [[suffix]] "a" or "ay" represents the Norse ''ey'', meaning "island". Those described as "[[Holm (island)|holms]]" are very small.<ref>Gammeltoft, Peder (2010) "[http://www.medievalists.net/2011/01/18/shetland-and-orkney-island-names-%E2%80%93-a-dynamic-group/ Shetland and Orkney Island-Names – A Dynamic Group]". ''Northern Lights, Northern Words''. Selected Papers from the FRLSU Conference, Kirkwall 2009, edited by Robert McColl Millar.</ref>

===The North Isles===
[[File:NR sheep.jpg|thumb|right|[[North Ronaldsay sheep]] are a [[feral|semi-feral]] breed that has evolved to eat seaweed.<ref name=SheepCentre>{{cite web|url=http://www.sheepcentre.co.uk/sheep_breeds.htm|publisher=Seven Sisters Sheep Centre|work=Sheep Breeds|title=Sheep Breeds: North Ronaldsay|access-date=23 April 2009|archive-date=25 April 2009|archive-url=https://web.archive.org/web/20090425140946/http://sheepcentre.co.uk/sheep_breeds.htm|url-status=live}}</ref> Their unique genetic inheritance makes them of interest to conservationists.<ref name="Lawson et al. 2007.">{{cite journal| journal=Heredity |year=2007 |volume=99 |issue=6 |pages=620–631 |title= Genetic structure of European sheep breeds|doi=10.1038/sj.hdy.6801039|pmid=17700634 |last1=Lawson Handley |first1=L-J |last2=Byrne |first2=K. |last3=Santucci |first3=F. |last4=Townsend |first4=S. |last5=Taylor |first5=M. |last6=Bruford |first6=M.

The northern group of islands is the most extensive and consists of a large number of moderately sized islands, linked to the Mainland by ferries and by air services. Farming, fishing and tourism are the main sources of income for most of the islands.<ref name=HS/><ref name=OS/>

The most northerly is [[North Ronaldsay]], which lies {{convert|4|km|mi|0}} beyond its nearest neighbour, [[Sanday, Orkney|Sanday]]. To the west is [[Westray]], which has a population of 550. It is connected by ferry and air to [[Papa Westray]], also known as "Papay". [[Eday]] is at the centre of the North Isles. The centre of the island is [[moorland]] and the island's main industries have been peat extraction and [[limestone]] [[quarry]]ing.<ref name=HS/>

[[Rousay]], [[Egilsay]] and [[Gairsay]] lie north of the west Mainland across the [[Eynhallow Sound]]. Rousay is well known for its ancient monuments, including the Quoyness [[chambered cairn]] and Egilsay has the ruins of the only round-towered church in Orkney. [[Wyre, Orkney|Wyre]] to the south-east contains the site of Cubbie Roo's castle. [[Stronsay]] and [[Papa Stronsay]] lie much further to the east across the Stronsay Firth. [[Auskerry]] is south of Stronsay and has a population of only five. [[Shapinsay]] and its [[Balfour Castle]] are a short distance north of Kirkwall.<ref name=HS/>

Other small uninhabited islands in the North Isles group include [[Calf of Eday]], [[Damsay]], [[Eynhallow]], [[Faray]], [[Helliar Holm]], [[Holm of Faray]], [[Holm of Huip]], [[Holm of Papa]], [[Holm of Scockness]], [[Kili Holm]], [[Linga Holm]], [[Muckle Green Holm]], [[Rusk Holm]] and [[Sweyn Holm]].<ref name=HS/><ref name=OS/>

A white wall obscures the lower floor of grey stone buildings gathered around its base.|[[Hoy Lighthouse|Hoy High Lighthouse]] on [[Graemsay]]]]

===The South Isles===
The southern group of islands surrounds [[Scapa Flow]]. [[Hoy, Orkney|Hoy]], to the west, is the second largest of the Orkney Isles and [[Ward Hill, Hoy|Ward Hill]] at its northern end is the highest elevation in the archipelago. The [[Old Man of Hoy]] is a well-known [[Stack (geology)|seastack]]. [[Graemsay]] and [[Flotta]] are both linked by ferry to the Mainland and Hoy, and the latter is known for its large oil terminal. [[South Walls]] has a 19th-century [[Martello tower]] and is connected to Hoy by the Ayre.<ref name=HS/>
[[Burray]] lies to the east of Scapa Flow and is linked by causeway to South Ronaldsay, which hosts cultural events such as the Festival of the Horse and the Boys' [[Ploughing Match]] on the third Saturday in August.<ref>{{cite web|url=http://www.orkneyjar.com/tradition/festivalofhorse.htm|title=The Festival of the Horse and the Boys' Ploughing Match|publisher=Orknejyar|access-date=6 April 2012|archive-date=16 November 2011|archive-url=https://web.archive.org/web/20111116053040/http://www.orkneyjar.com/tradition/festivalofhorse.htm|url-status=live}}</ref> It is also the location of the Neolithic [[Tomb of the Eagles]]. South Ronaldsay, Burray, [[Glimps Holm]], and [[Lamb Holm]] are connected by road to the Mainland by the [[Churchill Barriers]].<ref name=HS/>

Uninhabited South Islands include [[Calf of Flotta]], [[Cava (island)|Cava]], [[Copinsay]], [[Corn Holm]], [[Fara, Orkney|Fara]], [[Glimps Holm]], [[Hunda]], [[Lamb Holm]], [[Rysa Little]], [[Switha]] and [[Swona]]. The [[Pentland Skerries]] lie further south, closer to the Scottish mainland.<ref name=HS/><ref name=OS/>

==Economy==
The percentage of the Orkney population who are economically active is consistently higher than the Scottish average. In 2023 it was 89.8% compared to 77.9% for the latter, in which year average unemployment was 1.6%.<ref>Orkney Economic Review 2023, pp. 15, 21.</ref>

====Hydrogen manufacturing====
A March 2019 report by the [[BBC]] stated that "Orkney creates more clean electricity than its inhabitants need. Even after exporting to the UK national grid, the islands' winds, waves and tides generate about 130% of the electricity its population needs – all of it from clean sources".<ref>{{Cite web |url=https://www.bbc.com/future/article/20190327-the-tiny-islands-leading-the-way-in-hydrogen-power |title=How hydrogen is transforming these tiny Scottish islands |date=28 March 2019 |access-date=7 February 2021 |archive-date=14 October 2019 |archive-url=https://web.archive.org/web/20191014094933/https://www.bbc.com/future/article/20190327-the-tiny-islands-leading-the-way-in-hydrogen-power |url-status=live }}</ref> A report about sustainable energy in the islands listed two options. A new cable could be laid for exporting of energy to the mainland but another proposal has progressed rapidly since that time: making "excess renewable power into another fuel – such as hydrogen – and then [storing] it".<ref>{{Cite web |url=https://www.theguardian.com/environment/2019/jan/20/orkney-northern-powerhouse-electricity-wind-waves-surplus-power-hydrogen-fuel-cell |title=How Orkney leads the way for sustainable energy |website=[[TheGuardian.com]] |date=20 January 2019 |access-date=3 February 2021 |archive-date=7 November 2020 |archive-url=https://web.archive.org/web/20201107231036/https://www.theguardian.com/environment/2019/jan/20/orkney-northern-powerhouse-electricity-wind-waves-surplus-power-hydrogen-fuel-cell |url-status=live }}</ref><ref>{{Cite web |url=https://www.energyireland.ie/is-orkney-the-hydrogen-capital-of-the-world/ |title=Is Orkney the hydrogen capital of the world? 25 November 2019 |date=25 November 2019 |access-date=7 February 2021 |archive-date=14 February 2021 |archive-url=https://web.archive.org/web/20210214005639/https://www.energyireland.ie/is-orkney-the-hydrogen-capital-of-the-world/ |url-status=live }}</ref>

In May 2020, [[CNN]] published more specific information about the hydrogen plan:<ref>{{Cite web |url=https://www.cnn.com/2020/03/13/business/orkney-hydrogen-power/index.html |title=This small island chain is leading the way on hydrogen power' |website=[[CNN]] |date=13 March 2020 |access-date=3 February 2021 |archive-date=20 March 2021 |archive-url=https://web.archive.org/web/20210320144847/https://www.cnn.com/2020/03/13/business/orkney-hydrogen-power/index.html |url-status=live }}</ref><blockquote>Orkney's success in creating hydrogen using clean energy demonstrates that it can be done at scale. The islands are already using hydrogen to power vehicles, and it will soon be used to heat a local primary school. Now, Orkney is hoping to use hydrogen fuel cells to power a seagoing vessel able to transport both goods and passengers.</blockquote>

Additional specific information about the status of the hydrogen scheme was published in late November 2020 by Orkney Islands Council.<ref>{{Cite web |url=https://www.orkney.com/life/energy/hydrogen |title=Hydrogen |access-date=3 February 2021 |archive-date=20 January 2021 |archive-url=https://web.archive.org/web/20210120161755/https://www.orkney.com/life/energy/hydrogen |url-status=live }}</ref> A few weeks earlier, another report indicated that the world's first hydrogen-fueled ferry was to be tested on the Orkney Islands, using "a hydrogen/diesel dual fuel conversion system", developed by a consortium known as the HyDIME project. Initially hydrogen was to power only the auxiliary engine but the plan calls for later using this fuel for the primary engine. The report suggested that "if all goes well, hydrogen ferries could be sailing between Orkney's islands within six months".<ref>{{Cite web |url=https://electrek.co/2020/10/14/egeb-scotland-hydrogen-ferry-microwave/ |title=EGEB: Scotland trials world's first hydrogen ferry |date=14 October 2020 |access-date=3 February 2021 |archive-date=7 February 2021 |archive-url=https://web.archive.org/web/20210207225743/https://electrek.co/2020/10/14/egeb-scotland-hydrogen-ferry-microwave/ |url-status=live }}</ref>

The scheme planned to reduce the significant emissions that were created with older technology that heated buildings and water. This was part of the plan formulated by the Scottish government for the Highlands and Islands "to become the world's first net zero aviation region by 2040".<ref>{{cite web |url=https://hydrogeneast.uk/green-hydrogen-set-to-decarbonise-airport/ |title=Green hydrogen set to decarbonise airport |date=20 December 2020 |work=Hydrogen East |access-date=7 February 2021 |archive-date=2 February 2021 |archive-url=https://web.archive.org/web/20210202151112/https://hydrogeneast.uk/green-hydrogen-set-to-decarbonise-airport/ }}</ref>

Not all was going well as of 15 January 2021, according to ''[[The Times]]'', which stated that the project "has been hit by alleged sabotage after the destruction and theft of traps that have also killed and injured household pets and other animals" but added that the £6 million programme was supported by most islanders.<ref>{{Cite news |url=https://www.thetimes.com/article/stoats-of-orkney-weasel-out-of-cull-thanks-to-saboteurs-6070v3spn |title=Stoats of Orkney weasel out of cull thanks to saboteurs |access-date=2 February 2021 |archive-date=15 January 2021 |archive-url=https://web.archive.org/web/20210115073125/https://www.thetimes.co.uk/article/stoats-of-orkney-weasel-out-of-cull-thanks-to-saboteurs-6070v3spn |url-status=live |last1=Watson |first1=Jeremy }}</ref> Another news item stated that some of the traps had "caught and killed family pets as well as hundreds of other animals".<ref>{{Cite web |url=https://www.heraldscotland.com/news/19011526.row-stoat-cull-mass-deaths-animals/ |title=Row over stoat cull after mass deaths of animals |date=14 January 2021 |access-date=2 February 2021 |archive-date=19 January 2021 |archive-url=https://web.archive.org/web/20210119053847/https://www.heraldscotland.com/news/19011526.row-stoat-cull-mass-deaths-animals/ |url-status=live }}</ref> A subsequent report confirmed that "Police Scotland is investigating a number of incidents involving damage to and the theft of stoat traps in Orkney".<ref>{{Cite web |url=https://www.orcadian.co.uk/police-investigate-stoat-trap-damage/#:~:text=Police%20Scotland%20is%20investigating%20a,Deerness%20and%20Evie%20throughout%202020. |title=Police Investigate Stoat Trap Damage 11 January 2021 |date=11 January 2021 |access-date=2 February 2021 |archive-date=7 February 2021 |archive-url=https://web.archive.org/web/20210207122440/https://www.orcadian.co.uk/police-investigate-stoat-trap-damage/#:~:text=Police%20Scotland%20is%20investigating%20a,Deerness%20and%20Evie%20throughout%202020. |url-status=live }}</ref>

By 2024 the Orkney Native Wildlife Project had spent £7.9m trapping more than 6,300 stoats. Progress was impacted by the COVID-19 pandemic restrictions which prevented trapping in the 2020 breeding season.<ref>{{cite news |title=Orkney project granted extra £4m to remove stoats |url=https://www.bbc.co.uk/news/articles/c624zgp5314o |access-date=21 October 2025 |work=BBC News |date=14 August 2024}}</ref>

==Flag==
{{main|Flag of Orkney}}
A new flag for Orkney was adopted in 2007 following a public competition. It comprises a [[Nordic cross]] of blue and yellow on a red background. Previously the traditional flag of St Magnus (a red cross on a yellow background) had sometimes been used, but in 2001 it was ruled too similar to other flags to allow it to be formally registered as the area's flag.<ref>{{cite news |title=Postman designs new Orkney flag |url=https://news.bbc.co.uk/2/hi/uk_news/scotland/north_east/6541099.stm |access-date=8 October 2024 |work=BBC News |date=10 April 2007}}</ref>

==Freedom of Orkney==
The [[Freedom of the City|Freedom]] of Orkney is a ceremonial award issued by Orkney Islands Council. It can only be awarded twice during the term of any given Council, typically a period of five years. Its roots stretch back to the mid-15th century.<ref name=FOO>[https://www.orkney.gov.uk/latest-news/freedom-of-orkney-bestowed-on-royal-navy-northern-diving-group/ "Freedom of Orkney Bestowed on Royal Navy Northern Diving Group".] Orkney Islands Council.
