Renewable energy often displaces conventional fuels in four areas: electricity generation , hot water / space heating , transportation , and rural (off-grid) energy services. Although almost all forms of renewable energy cause much fewer carbon emissions than fossil fuels,

The Camborne School of Mines Association serves all former students of the school and was founded in 1896. It has approximately 1,000 members. CSM is an internationally recognised centre for research related to the formation, discovery, extraction and utilisation of the Earth's natural resources, and subsequent remediation. The applied nature of much of

Wind power generation can vary significantly not only day-to-day, but even month-to-month. This poses a challenge when transitioning away from fossil fuels: energy demand will often be higher or lower than what renewables can provide. Both scenarios can cause electricity grids to become overloaded, leading to power outages . In

Others are the Charter Fragment , the earliest known continuous text in the Cornish language, apparently part of a play about a medieval marriage, and Pascon agan Arluth ( The Passion of Our Lord ), a poem probably intended for personal worship, were written during this period, probably in the second half of the 14th century. Another important text,

For example, enhanced geothermal systems involve drilling around 10 kilometres (6.2 mi) into the Earth, breaking apart hot rocks and extracting the heat using water. In theory, this type of geothermal energy extraction could be done anywhere on Earth. There are also other renewable energy technologies that are still under development, including enhanced geothermal systems , concentrated solar power , cellulosic ethanol , and marine energy . These technologies are not yet widely demonstrated or have limited commercialization. Some may have potential comparable to other renewable energy technologies, but still depend on further breakthroughs from research, development and engineering. Enhanced geothermal systems (EGS) are

From this period also are the hagiographical dramas Beunans Meriasek ( The Life of Meriasek ) and Bewnans Ke ( The Life of Ke ), both of which feature as an antagonist the villainous and tyrannical King Tewdar (or Teudar), a historical medieval king in Armorica and Cornwall, who, in these plays, has been interpreted as
2240-638: A more energy-dense biofuel like ethanol. Wood is the most significant biomass energy source as of 2012 and is usually sourced from a trees cleared for silvicultural reasons or fire prevention . Municipal wood waste – for instance, construction materials or sawdust – is also often burned for energy. The biggest per-capita producers of wood-based bioenergy are heavily forested countries like Finland, Sweden, Estonia, Austria, and Denmark. Bioenergy can be environmentally destructive if old-growth forests are cleared to make way for crop production. In particular, demand for palm oil to produce biodiesel has contributed to
2380-506: A new type of geothermal power which does not require natural hot water reservoirs or steam to generate power. Most of the underground heat within drilling reach is trapped in solid rocks, not in water. EGS technologies use hydraulic fracturing to break apart these rocks and release the heat they contain, which is then harvested by pumping water into the ground. The process is sometimes known as "hot dry rock" (HDR). Unlike conventional geothermal energy extraction, EGS may be feasible anywhere in
2520-631: A number of orthographic, and phonological, distinctions not found in Unified Cornish. Kernewek Kemmyn is characterised by the use of universal ⟨k⟩ for /k/ (instead of ⟨c⟩ before back vowels as in Unified); ⟨hw⟩ for /hw/, instead of ⟨wh⟩ as in Unified; and ⟨y⟩, ⟨oe⟩, and ⟨eu⟩ to represent the phonemes /ɪ/, /o/, and /œ/ respectively, which are not found in Unified Cornish. Criticism of all of these systems, especially Kernewek Kemmyn, by Nicolas Williams, resulted in

These functions are instead fulfilled by periphrastic constructions involving a verb and various prepositional phrases. The grammar of Cornish shares with other Celtic languages a number of features which, while not unique, are unusual in an Indo-European context. The grammatical features most unfamiliar to English speakers of

However, prominent research faces hurdles, Sun Catalytix a MIT spin-off stopped scaling up their prototype fuel-cell in 2012 because it offers few savings over other ways to make hydrogen from sunlight. Most new renewables are solar, followed by wind then hydro then bioenergy. Investment in renewables, especially solar, tends to be more effective in creating jobs than coal, gas or oil. Worldwide, renewables employ about 12 million people as of 2020, with solar PV being
3500-525: A variety of reasons by Jon Mills and Nicholas Williams , including making phonological distinctions that they state were not made in the traditional language c. 1500 , failing to make distinctions that they believe were made in the traditional language at this time, and the use of an orthography that deviated too far from the traditional texts and Unified Cornish. Also during this period, Richard Gendall created his Modern Cornish system (also known as Revived Late Cornish), which used Late Cornish as

It originates from several different sources , of which the most significant is slow radioactive decay of minerals contained in the Earth's interior , as well as some leftover heat from the formation of the Earth . Some of the heat is generated near the Earth's surface in the crust, but some also flows from deep within the Earth from
4060-471: Is a more economical means of long-term renewable energy storage, in terms of capital expenditures compared to pumped hydroelectric or batteries. Solar power produced around 1.3 terrawatt-hours (TWh) worldwide in 2022, representing 4.6% of the world's electricity. Almost all of this growth has happened since 2010. Solar energy can be harnessed anywhere that receives sunlight; however, the amount of solar energy that can be harnessed for electricity generation
4200-537: Is a technology for generating electricity by mixing fresh water and salty sea water in large power cells. Most marine energy harvesting technologies are still at low technology readiness levels and not used at large scales. Tidal energy is generally considered the most mature, but has not seen wide deployment. The world's largest tidal power station is on Sihwa Lake , South Korea, which produces around 550 gigawatt-hours of electricity per year.

Renewable energy is often deployed together with further electrification . This has several benefits: electricity can move heat and vehicles efficiently and is clean at the point of consumption. Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity , bioenergy , or geothermal power . Renewable energy systems have rapidly become more efficient and cheaper over

In general, renewable energy sources cause much lower emissions than fossil fuels. The International Energy Agency estimates that to achieve net zero emissions by 2050, 90% of global electricity generation will need to be produced from renewable sources. Renewables also cause much less air pollution than fossil fuels, improving public health, and are less noisy .

Jenner wrote about the Cornish language in 1905, "one may fairly say that most of what there was of it has been preserved, and that it has been continuously preserved, for there has never been a time when there were not some Cornishmen who knew some Cornish." The revival focused on reconstructing and standardising

#17328723899318680-829: The Cornish language ceased, and responsibility transferred to Cornwall Council. Until around the middle of the 11th century, Old Cornish scribes used a traditional spelling system shared with Old Breton and Old Welsh, based on the pronunciation of British Latin . By the time of the Vocabularium Cornicum , usually dated to around 1100, Old English spelling conventions, such as the use of thorn (Þ, þ) and eth (Ð, ð) for dental fricatives , and wynn (Ƿ, ƿ) for /w/, had come into use, allowing documents written at this time to be distinguished from Old Welsh, which rarely uses these characters, and Old Breton, which does not use them at all. Old Cornish features include using initial ⟨ch⟩, ⟨c⟩, or ⟨k⟩ for /k/, and, in internal and final position, ⟨p⟩, ⟨t⟩, ⟨c⟩, ⟨b⟩, ⟨d⟩, and ⟨g⟩ are generally used for

Around 1700, Edward Lhuyd visited Cornwall, introducing his own partly phonetic orthography that he used in his Archaeologia Britannica , which was adopted by some local writers, leading to the use of some Lhuydian features such as the use of circumflexes to denote long vowels, ⟨k⟩ before front vowels, word-final ⟨i⟩, and the use of ⟨dh⟩ to represent the voiced dental fricative /ð/. After

Anthony Fletcher points out that this rebellion was primarily motivated by religious and economic, rather than linguistic, concerns. The rebellion prompted a heavy-handed response from the government, and 5,500 people died during the fighting and

9940-476: The beginning of the Celtic Revival in the late 19th century, provided the groundwork for a Cornish language revival movement. Notwithstanding the uncertainty over who was the last speaker of Cornish, researchers have posited the following numbers for the prevalence of the language between 1050 and 1800. In 1904, the Celtic language scholar and Cornish cultural activist Henry Jenner published A Handbook of
10080-617: The body, including lof 'hand' and dans 'tooth'. Inherited adjectives with an Indo-European etymology include newyth 'new', ledan 'broad, wide', rud 'red', hen 'old', iouenc 'young', and byw 'alive, living'. Several Celtic or Brittonic words cannot be reconstructed to Proto-Indo-European, and are suggested to have been borrowed from unknown substrate language(s) at an early stage, such as Proto-Celtic or Proto-Brittonic. Proposed examples in Cornish include coruf 'beer' and broch 'badger'. Other words in Cornish inherited direct from Proto-Celtic include
10220-446: The burning of fossil fuels. The potential worldwide savings in health care costs have been estimated at trillions of dollars annually. The two most important forms of renewable energy, solar and wind, are intermittent energy sources : they are not available constantly, resulting in lower capacity factors . In contrast, fossil fuel power plants are usually able to produce precisely the amount of energy an electricity grid requires at
10360-778: The cold outer space. Solar energy hits the surface and atmosphere of the earth and produces heat. Using various theorized devices like emissive energy harvester (EEH) or thermoradiative diode, this energy flow can be converted into electricity. In theory, this technology can be used during nighttime. Producing liquid fuels from oil-rich (fat-rich) varieties of algae is an ongoing research topic. Various microalgae grown in open or closed systems are being tried including some systems that can be set up in brownfield and desert lands. There have been numerous proposals for space-based solar power , in which very large satellites with photovoltaic panels would be equipped with microwave transmitters to beam power back to terrestrial receivers. A 2024 study by
10500-550: The creation of Unified Cornish Revised, a modified version of Nance's orthography, featuring: an additional phoneme not distinguished by Nance, "ö in German schön ", represented in the UCR orthography by ⟨ue⟩; replacement of ⟨y⟩ with ⟨e⟩ in many words; internal ⟨h⟩ rather than ⟨gh⟩; and use of final ⟨b⟩, ⟨g⟩, and ⟨dh⟩ in stressed monosyllables. A Standard Written Form , intended as a compromise orthography for official and educational purposes,
10640-543: The crops used to produce bioethanol and biodiesel are grown specifically for this purpose, although used cooking oil accounted for 14% of the oil used to produce biodiesel as of 2015. The biomass used to produce biofuels varies by region. Maize is the major feedstock in the United States, while sugarcane dominates in Brazil. In the European Union, where biodiesel is more common than bioethanol, rapeseed oil and palm oil are
10780-611: The culture of Cornwall. Examples include atal 'mine waste' and beetia 'to mend fishing nets'. Foogan and hogan are different types of pastries. Troyl is a 'traditional Cornish dance get-together' and Furry is a specific kind of ceremonial dance that takes place in Cornwall. Certain Cornish words may have several translation equivalents in English, so for instance lyver may be translated into English as either 'book' or 'volume' and dorn can mean either 'hand' or 'fist'. As in other Celtic languages, Cornish lacks
10920-518: The defeat of the Britons at the Battle of Deorham in about 577. The western dialects eventually evolved into modern Welsh and the now extinct Cumbric , while Southwestern Brittonic developed into Cornish and Breton, the latter as a result of emigration to parts of the continent, known as Brittany over the following centuries. The area controlled by the southwestern Britons was progressively reduced by
11060-412: The deforestation of tropical rainforests in Brazil and Indonesia. In addition, burning biomass still produces carbon emissions, although much less than fossil fuels (39 grams of CO 2 per megajoule of energy, compared to 75 g/MJ for fossil fuels). Some biomass sources are unsustainable at current rates of exploitation (as of 2017). Biofuels are primarily used in transportation, providing 3.5% of
11200-602: The degrees of MPhil and PhD. Work is funded by the research councils, industry and charitable trusts and is supported by the school's technical staff and analytical facilities. The facilities and services at CSM are available to students, academic staff, research partners, and individuals and organisations from the business community. Short Courses and Continuing Professional Development (CPD) include Renewable Energy Industry Training Modules, and Quarry Shotfiring / Explosives Supervisor courses (EPIC-validated). The school's geochemical and mineralogical analytical laboratories include
11340-497: The dental fricatives /θ/ and /ð/, a usage which is unique to Middle Cornish and is never found in Middle English. Middle Cornish scribes tend to use ⟨c⟩ for /k/ before back vowels, and ⟨k⟩ for /k/ before front vowels, though this is not always true, and this rule is less consistent in certain texts. Middle Cornish scribes almost universally use ⟨wh⟩ to represent /ʍ/ (or /hw/), as in Middle English. Middle Cornish, especially towards
11480-431: The end of this period, tends to use orthographic ⟨g⟩ and ⟨b⟩ in word-final position in stressed monosyllables, and ⟨k⟩ and ⟨p⟩ in word-final position in unstressed final syllables, to represent the reflexes of late Brittonic /ɡ/ and /b/, respectively. Written sources from this period are often spelled following English spelling conventions since many of the writers of the time had not been exposed to Middle Cornish texts or
11620-436: The evidence of this rhyme, of what there was to lose by neglecting John Davey." The search for the last speaker is hampered by a lack of transcriptions or audio recordings, so that it is impossible to tell from this distance whether the language these people were reported to be speaking was Cornish, or English with a heavy Cornish substratum , nor what their level of fluency was. Nevertheless, this academic interest, along with
11760-475: The existence of multiple orthographies was unsustainable with regards to using the language in education and public life, as none had achieved a wide consensus. A process of unification was set about which resulted in the creation of the public-body Cornish Language Partnership in 2005 and agreement on a Standard Written Form in 2008. In 2010 a new milestone was reached when UNESCO altered its classification of Cornish, stating that its previous label of "extinct"
11900-587: The expansion of Wessex over the next few centuries. During the Old Cornish ( Kernewek Koth ) period (800–1200), the Cornish-speaking area was largely coterminous with modern-day Cornwall , after the Saxons had taken over Devon in their south-westward advance, which probably was facilitated by a second migration wave to Brittany that resulted in the partial depopulation of Devon. The earliest written record of
12040-455: The family, names for various kinds of artisans and their tools, flora, fauna, and household items. The manuscript was widely thought to be in Old Welsh until the 18th century when it was identified as Cornish by Edward Lhuyd . Some Brittonic glosses in the 9th-century colloquy De raris fabulis were once identified as Old Cornish, but they are more likely Old Welsh, possibly influenced by
12180-585: The fastest-growing renewable energy technology. It is cheap, low-maintenance and scalable; adding to an existing PV installation as demanded arises is simple. Its main disadvantage is its poor performance in cloudy weather. PV systems range from small, residential and commercial rooftop or building integrated installations, to large utility-scale photovoltaic power station . A household's solar panels can either be used for just that household or, if connected to an electrical grid, can be aggregated with millions of others. The first utility-scale solar power plant
12320-548: The fuel cycle employed, extract almost all of the energy contained in uranium or thorium , decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors , which extract less than 1% of the energy in the actinide metal (uranium or thorium) mined from the earth. The high fuel-efficiency of breeder reactors could greatly reduce concerns about fuel supply, energy used in mining, and storage of radioactive waste . With seawater uranium extraction (currently too expensive to be economical), there
12460-736: The horizontal axis units currently in use. As offshore wind speeds average ~90% greater than that of land, offshore resources can contribute substantially more energy than land-stationed turbines. Investments in wind technologies reached USD 161 billion in 2020, with onshore wind dominating at 80% of total investments from 2013 to 2022. Offshore wind investments nearly doubled to USD 41 billion between 2019 and 2020, primarily due to policy incentives in China and expansion in Europe. Global wind capacity increased by 557 GW between 2013 and 2021, with capacity additions increasing by an average of 19% each year. Since water
12600-400: The individualised nature of language take-up. Nevertheless, there is recognition that the number of Cornish speakers is growing. From before the 1980s to the end of the 20th century there was a sixfold increase in the number of speakers to around 300. One figure for the number of people who know a few basic words, such as knowing that "Kernow" means "Cornwall", was 300,000; the same survey gave
12740-402: The inhabitants can speak no word of Cornish, but very few are ignorant of the English; and yet some so affect their own, as to a stranger they will not speak it; for if meeting them by chance, you inquire the way, or any such matter, your answer shall be, " Meea navidna caw zasawzneck ," "I [will] speak no Saxonage." The Late Cornish ( Kernewek Diwedhes ) period from 1600 to about 1800 has
12880-938: The language are the initial consonant mutations , the verb–subject–object word order, inflected prepositions , fronting of emphasised syntactic elements and the use of two different forms for 'to be'. Cornish has initial consonant mutation : The first sound of a Cornish word may change according to grammatical context. As in Breton, there are four types of mutation in Cornish (compared with three in Welsh , two in Irish and Manx and one in Scottish Gaelic ). These changes apply to only certain letters (sounds) in particular grammatical contexts, some of which are given below: Cornish has no indefinite article . Porth can either mean 'harbour' or 'a harbour'. In certain contexts, unn can be used, with
13020-406: The language as critically endangered , stating that its former classification of the language as extinct was no longer accurate. The language has a growing number of second-language speakers, and a very small number of families now raise children to speak revived Cornish as a first language . Cornish is currently recognised under the European Charter for Regional or Minority Languages , and
13160-407: The language despite not being fluent nor using the language in daily life, generally survive even longer. The traditional view that Dolly Pentreath (1692–1777) was the last native speaker of Cornish has been challenged, and in the 18th and 19th centuries there was academic interest in the language and in attempting to find the last speaker of Cornish. It has been suggested that, whereas Pentreath
13300-454: The language is often described as an important part of Cornish identity, culture and heritage. Since the revival of the language, some Cornish textbooks and works of literature have been published, and an increasing number of people are studying the language. Recent developments include Cornish music , independent films , and children's books. A small number of people in Cornwall have been brought up to be bilingual native speakers, and
13440-588: The language is taught in schools and appears on street nameplates. The first Cornish-language day care opened in 2010. Cornish is a Southwestern Brittonic language, a branch of the Insular Celtic section of the Celtic language family , which is a sub-family of the Indo-European language family. Brittonic also includes Welsh , Breton , Cumbric and possibly Pictish , the last two of which are extinct . Scottish Gaelic , Irish and Manx are part of
13580-573: The language regularly, with 5,000 people having a basic conversational ability in the language. A report on the 2011 Census published in 2013 by the Office for National Statistics placed the number of speakers at somewhere between 325 and 625. In 2017 the ONS released data based on the 2011 Census that placed the number of speakers at 557 people in England and Wales who declared Cornish to be their main language, 464 of whom lived in Cornwall. The 2021 census listed
13720-438: The language, including coining new words for modern concepts, and creating educational material in order to teach Cornish to others. In 1929 Robert Morton Nance published his Unified Cornish ( Kernewek Unys ) system, based on the Middle Cornish literature while extending the attested vocabulary with neologisms and forms based on Celtic roots also found in Breton and Welsh, publishing a dictionary in 1938. Nance's work became
13860-408: The main feedstocks. China, although it produces comparatively much less biofuel, uses mostly corn and wheat. In many countries, biofuels are either subsidized or mandated to be included in fuel mixtures . There are many other sources of bioenergy that are more niche, or not yet viable at large scales. For instance, bioethanol could be produced from the cellulosic parts of crops, rather than only
14000-504: The main sequence of stellar evolution. Artificial photosynthesis uses techniques including nanotechnology to store solar electromagnetic energy in chemical bonds by splitting water to produce hydrogen and then using carbon dioxide to make methanol. Researchers in this field strived to design molecular mimics of photosynthesis that use a wider region of the solar spectrum, employ catalytic systems made from abundant, inexpensive materials that are robust, readily repaired, non-toxic, stable in
14140-453: The maximum output for the particular turbine. Areas where winds are stronger and more constant, such as offshore and high-altitude sites, are preferred locations for wind farms. Wind-generated electricity met nearly 4% of global electricity demand in 2015, with nearly 63 GW of new wind power capacity installed. Wind energy was the leading source of new capacity in Europe, the US and Canada, and
14280-436: The meaning 'a certain, a particular', e.g. unn porth 'a certain harbour'. There is, however, a definite article an 'the', which is used for all nouns regardless of their gender or number, e.g. an porth 'the harbour'. Cornish nouns belong to one of two grammatical genders , masculine and feminine, but are not inflected for case . Nouns may be singular or plural. Plurals can be formed in various ways, depending on
14420-472: The medium-term, this variability may require keeping some gas-fired power plants or other dispatchable generation on standby until there is enough energy storage, demand response , grid improvement, and/or baseload power from non-intermittent sources. In the long-term, energy storage is an important way of dealing with intermittency. Using diversified renewable energy sources and smart grids can also help flatten supply and demand. Sector coupling of
14560-437: The mid 18th century, and there is some evidence for traditional speakers of the language persisting into the 19th century. Cornish became extinct as a living community language in Cornwall by the end of the 18th century , although knowledge of Cornish, including speaking ability to a certain extent, persisted within some families and individuals. A revival started in the early 20th century, and in 2010 UNESCO reclassified
14700-415: The noun: Renewable energy Renewable energy (or green energy ) is energy from renewable natural resources that are replenished on a human timescale . The most widely used renewable energy types are solar energy , wind power , and hydropower . Bioenergy and geothermal power are also significant in some countries. Some also consider nuclear power a renewable power source , although this
14840-495: The number of Cornish speakers at 563. A study that appeared in 2018 established the number of people in Cornwall with at least minimal skills in Cornish, such as the use of some words and phrases, to be more than 3,000, including around 500 estimated to be fluent. The Institute of Cornish Studies at the University of Exeter is working with the Cornish Language Partnership to study the Cornish language revival of
14980-410: The number of people able to have simple conversations as 3,000. The Cornish Language Strategy project commissioned research to provide quantitative and qualitative evidence for the number of Cornish speakers: due to the success of the revival project it was estimated that 2,000 people were fluent (surveyed in spring 2008), an increase from the estimated 300 people who spoke Cornish fluently suggested in
15120-415: The orthography and rhyme used in the historical texts, comparison with the other Brittonic languages Breton and Welsh, and the work of the linguist Edward Lhuyd , who visited Cornwall in 1700 and recorded the language in a partly phonetic orthography. Cornish is a Celtic language, and the majority of its vocabulary, when usage frequency is taken into account, at every documented stage of its history
15260-826: The other Brittonic languages. The first sound change to distinguish Cornish from both Breton and Welsh, the assibilation of the dental stops /t/ and /d/ in medial and final position, had begun by the time of the Vocabularium Cornicum , c. 1100 or earlier. This change, and the subsequent, or perhaps dialectical, palatalization (or occasional rhotacization in a few words) of these sounds, results in orthographic forms such as Middle Cornish tas 'father', Late Cornish tâz (Welsh tad ), Middle Cornish cresy 'believe', Late Cornish cregy (Welsh credu ), and Middle Cornish gasa 'leave', Late Cornish gara (Welsh gadael ). A further characteristic sound change, pre-occlusion , occurred during
15400-479: The past 30 years. A large majority of worldwide newly installed electricity capacity is now renewable. Renewable energy sources, such as solar and wind power, have seen significant cost reductions over the past decade, making them more competitive with traditional fossil fuels. In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity. From 2011 to 2021, renewable energy grew from 20% to 28% of global electricity supply. Power from
15540-413: The phonemes /b/, /d/, /ɡ/, /β/, /ð/, and /ɣ/ respectively, meaning that the results of Brittonic lenition are not usually apparent from the orthography at this time. Middle Cornish orthography has a significant level of variation, and shows influence from Middle English spelling practices. Yogh (Ȝ ȝ) is used in certain Middle Cornish texts, where it is used to represent a variety of sounds, including
15680-571: The power generation sector with other sectors may increase flexibility: for example the transport sector can be coupled by charging electric vehicles and sending electricity from vehicle to grid . Similarly the industry sector can be coupled by hydrogen produced by electrolysis, and the buildings sector by thermal energy storage for space heating and cooling. Building overcapacity for wind and solar generation can help ensure sufficient electricity production even during poor weather. In optimal weather, it may be necessary to curtail energy generation if it
15820-482: The primary challenges for new developments. It is popular to repower old dams thereby increasing their efficiency and capacity as well as quicker responsiveness on the grid. Where circumstances permit existing dams such as the Russell Dam built in 1985 may be updated with "pump back" facilities for pumped-storage which is useful for peak loads or to support intermittent wind and solar power. Because dispatchable power
15960-447: The publication of Jenner's Handbook of the Cornish Language , the earliest revivalists used Jenner's orthography, which was influenced by Lhuyd's system. This system was abandoned following the development by Nance of a "unified spelling", later known as Unified Cornish , a system based on a standardization of the orthography of the early Middle Cornish texts. Nance's system was used by almost all Revived Cornish speakers and writers until
16100-467: The rebellion's aftermath. Government officials then directed troops under the command of Sir Anthony Kingston to carry out pacification operations throughout the West Country. Kingston subsequently ordered the executions of numerous individuals suspected of involvement with the rebellion as part of the post-rebellion reprisals. The rebellion eventually proved a turning-point for the Cornish language, as
16240-499: The reign of Henry VIII, an account was given by Andrew Boorde in his 1542 Boke of the Introduction of Knowledge . He states, " In Cornwall is two speches, the one is naughty Englysshe, and the other is Cornysshe speche. And there be many men and women the which cannot speake one worde of Englysshe, but all Cornyshe. " When Parliament passed the Act of Uniformity 1549 , which established
16380-670: The required grades since 1910, and in 1974 it was accredited by the Council for National Academic Awards . Notable Associates include Lord Eurby D.S.O., M.C. (born 1883) and Sam E. Jonah ( KBE ) (ACSM), chief executive of Ashanti Goldfields. The CSM student body is a community within the larger student body of the Combined Universities in Cornwall which includes students from both Falmouth University and University of Exeter Cornwall Campus . The CSM student association organises social events and helps students with any issues. Sport within
16520-549: The research is indicated by significant international industrial collaboration. Research within CSM is co-ordinated by the three multidisciplinary groups. These draw upon the school's research expertise in mining and minerals engineering, geology, renewable energy and environmental science , and their links with colleagues in the University of Exeter's Department of Geography. Each group is led by full-time academic staff, and includes postdoctoral research fellows, experimental officers and postgraduate research students working towards
16660-480: The school is strong and there are team sports run under the CSM name in local leagues, but are open to any students at Tremough. A key event in the school's sporting calendar is the annual Bottle Match against Royal School of Mines which is organised by the student association. Each year students take part in the International Mining Games. In 2012 and 2018 CSM hosted the games, at King Edward Mine ,
16800-585: The second largest in China. In Denmark, wind energy met more than 40% of its electricity demand while Ireland, Portugal and Spain each met nearly 20%. Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome. This would require wind turbines to be installed over large areas, particularly in areas of higher wind resources, such as offshore, and likely also industrial use of new types of VAWT turbines in addition to
16940-523: The sector's increasing maturity and cost reductions, particularly in solar photovoltaic (PV), which accounted for 90% of total investments. China and the United States were the main recipients, collectively making up about half of all solar investments since 2013. Despite reductions in Japan and India due to policy changes and COVID-19 , growth in China, the United States, and a significant increase from Vietnam's feed-in tariff program offset these declines. Globally,
17080-418: The seed as is common today. Sweet sorghum may be a promising alternative source of bioethanol, due to its tolerance of a wide range of climates. Cow dung can be converted into methane. There is also a great deal of research involving algal fuel , which is attractive because algae is a non-food resource, grows around 20 times faster than most food crops, and can be grown almost anywhere. Geothermal energy
17220-465: The separate Goidelic branch of Insular Celtic. Joseph Loth viewed Cornish and Breton as being two dialects of the same language, claiming that "Middle Cornish is without doubt closer to Breton as a whole than the modern Breton dialect of Quiberon [ Kiberen ] is to that of Saint-Pol-de-Léon [ Kastell-Paol ]." Also, Kenneth Jackson argued that it is almost certain that Cornish and Breton would have been mutually intelligible as long as Cornish
17360-451: The solar sector added 714 gigawatts (GW) of solar PV and concentrated solar power (CSP) capacity between 2013 and 2021, with a notable rise in large-scale solar heating installations in 2021, especially in China, Europe, Turkey, and Mexico. A photovoltaic system , consisting of solar cells assembled into panels , converts light into electrical direct current via the photoelectric effect . PV has several advantages that make it by far
17500-513: The sun and wind accounted for most of this increase, growing from a combined 2% to 10%. Use of fossil energy shrank from 68% to 62%. In 2022, renewables accounted for 30% of global electricity generation and are projected to reach over 42% by 2028. Many countries already have renewables contributing more than 20% of their total energy supply, with some generating over half or even all their electricity from renewable sources. The main motivation to replace fossil fuels with renewable energy sources
17640-468: The technology employing the most at almost 4 million. However, as of February 2024, the world's supply of workforce for solar energy is lagging greatly behind demand as universities worldwide still produce more workforce for fossil fuels than for renewable energy industries. In 2021, China accounted for almost half of the global increase in renewable electricity. There are 3,146 gigawatts installed in 135 countries, while 156 countries have laws regulating
17780-407: The ten biggest solar power stations are in China, including the biggest, Golmud Solar Park in China. Unlike photovoltaic cells that convert sunlight directly into electricity, solar thermal systems convert it into heat. They use mirrors or lenses to concentrate sunlight onto a receiver, which in turn heats a water reservoir. The heated water can then be used in homes. The advantage of solar thermal
17920-501: The term is not synonymous with low-carbon energy . Some non-renewable sources of energy, such as nuclear power , generate almost no emissions, while some renewable energy sources can be very carbon-intensive, such as the burning of biomass if it is not offset by planting new plants. Renewable energy is also distinct from sustainable energy , a more abstract concept that seeks to group energy sources based on their overall permanent impact on future generations of humans. For example, biomass
18060-484: The use of land for renewable installations. Like all mining, the extraction of minerals required for many renewable energy technologies also results in environmental damage . In addition, although most renewable energy sources are sustainable , some are not. Renewable energy is usually understood as energy harnessed from continuously occurring natural phenomena. The International Energy Agency defines it as "energy derived from natural processes that are replenished at
18200-484: The world's transport energy demand in 2022, up from 2.7% in 2010. Biojet is expected to be important for short-term reduction of carbon dioxide emissions from long-haul flights. Aside from wood, the major sources of bioenergy are bioethanol and biodiesel . Bioethanol is usually produced by fermenting the sugar components of crops like sugarcane and maize , while biodiesel is mostly made from oils extracted from plants, such as soybean oil and corn oil . Most of
18340-502: The world, depending on the cost of drilling. EGS projects have so far primarily been limited to demonstration plants , as the technology is capital-intensive due to the high cost of drilling. Marine energy (also sometimes referred to as ocean energy) is the energy carried by ocean waves , tides , salinity , and ocean temperature differences . Technologies to harness the energy of moving water include wave power , marine current power , and tidal power . Reverse electrodialysis (RED)
18480-532: The years 1550–1650 as a century of immense damage for the language, and its decline can be traced to this period. In 1680 William Scawen wrote an essay describing 16 reasons for the decline of Cornish, among them the lack of a distinctive Cornish alphabet , the loss of contact between Cornwall and Brittany , the cessation of the miracle plays, loss of records in the Civil War, lack of a Cornish Bible and immigration to Cornwall. Mark Stoyle , however, has argued that
18620-455: Was 1,360 GW. Only a third of the world's estimated hydroelectric potential of 14,000 TWh/year has been developed. New hydropower projects face opposition from local communities due to their large impact, including relocation of communities and flooding of wildlife habitats and farming land. High cost and lead times from permission process, including environmental and risk assessments, with lack of environmental and social acceptance are therefore
18760-552: Was a living language, and that Cornish and Breton are especially closely related to each other and less closely related to Welsh. Cornish evolved from the Common Brittonic spoken throughout Britain south of the Firth of Forth during the British Iron Age and Roman period . As a result of westward Anglo-Saxon expansion , the Britons of the southwest were separated from those in modern-day Wales and Cumbria , which Jackson links to
18900-517: Was built in 1982 in Hesperia, California by ARCO . The plant was not profitable and was sold eight years later. However, over the following decades, PV cells became significantly more efficient and cheaper. As a result, PV adoption has grown exponentially since 2010. Global capacity increased from 230 GW at the end of 2015 to 890 GW in 2021. PV grew fastest in China between 2016 and 2021, adding 560 GW, more than all advanced economies combined. Four of
19040-696: Was introduced in 2008, although a number of previous orthographic systems remain in use and, in response to the publication of the SWF, another new orthography, Kernowek Standard , was created, mainly by Nicholas Williams and Michael Everson, which is proposed as an amended version of the Standard Written Form. The phonological system of Old Cornish, inherited from Proto-Southwestern Brittonic and originally differing little from Old Breton and Old Welsh, underwent various changes during its Middle and Late phases, eventually resulting in several characteristics not found in
19180-516: Was no longer accurate. Speakers of Cornish reside primarily in Cornwall , which has a population of 563,600 (2017 estimate). There are also some speakers living outside Cornwall, particularly in the countries of the Cornish diaspora , as well as in other Celtic nations . Estimates of the number of Cornish speakers vary according to the definition of a speaker, and is difficult to determine accurately due to
19320-464: Was owned & run by Holman Brothers , Camborne. The museum at CSM is devoted to worldwide geology with particular emphasis on mining and mineralisation. It holds a significant and comprehensive systematic collection including fluorescent, gem and ore minerals, together with suites of minerals and host rocks from important mining areas all over the world, though a significant part of its collection derives from south west England. The collection serves as
19460-567: Was probably the last monolingual speaker, the last native speaker may have been John Davey of Zennor, who died in 1891. However, although it is clear Davey possessed some traditional knowledge in addition to having read books on Cornish, accounts differ of his competence in the language. Some contemporaries stated he was able to converse on certain topics in Cornish whereas others affirmed they had never heard him claim to be able to do so. Robert Morton Nance , who reworked and translated Davey's Cranken Rhyme, remarked, "There can be no doubt, after
19600-403: Was probably the last prose written in the traditional language. In his letter, he describes the sociolinguistics of the Cornish language at the time, stating that there are no more than four or five old people in his village who can still speak Cornish, concluding with the remark that Cornish is no longer known by young people. However, the last recorded traditional Cornish literature may have been
