Notable pre-modern and early-modern English writers include Geoffrey Chaucer (14th century), Thomas Malory (15th century), Sir Thomas More (16th century), John Bunyan (17th century) and John Milton (17th century). In the 18th century Daniel Defoe (author of Robinson Crusoe) and Samuel Richardson were pioneers of the modern novel. In the 19th century there followed further innovation by Jane Austen, the gothic novelist Mary Shelley, the children's writer Lewis Carroll, the Brontë sisters, the social campaigner Charles Dickens, the naturalist Thomas Hardy, the realist George Eliot, the visionary poet William Blake and Romantic poet William Wordsworth. 20th-century English writers include the science-fiction novelist H. G. Wells; the writers of children's classics Rudyard Kipling, A. A. Milne (the creator of Winnie-the-Pooh), Roald Dahl and Enid Blyton; the controversial D. H. Lawrence; the modernist Virginia Woolf; the satirist Evelyn Waugh; the prophetic novelist George Orwell; the popular novelists W. Somerset Maugham and Graham Greene; the crime writer Agatha Christie (the best-selling novelist of all time); Ian Fleming (the creator of James Bond); the poets W.H. Auden, Philip Larkin and Ted Hughes; the fantasy writers J. R. R. Tolkien, C. S. Lewis and J. K. Rowling; the graphic novelists Alan Moore and Neil Gaiman.
Coal production played a key role in the UK economy in the 19th and 20th centuries. In the mid-1970s, 130 million tonnes of coal were produced annually, not falling below 100 million tonnes until the early 1980s. During the 1980s and 1990s the industry was scaled back considerably. In 2011, the UK produced 18.3 million tonnes of coal. In 2005 it had proven recoverable coal reserves of 171 million tons. The UK Coal Authority has stated there is a potential to produce between 7 billion tonnes and 16 billion tonnes of coal through underground coal gasification (UCG) or 'fracking', and that, based on current UK coal consumption, such reserves could last between 200 and 400 years. Environmental and social concerns have been raised over chemicals getting into the water table and minor earthquakes damaging homes.
More InfoIn the late 1990s, nuclear power plants contributed around 25 per cent of total annual electricity generation in the UK, but this has gradually declined as old plants have been shut down and ageing-related problems affect plant availability. In 2012, the UK had 16 reactors normally generating about 19 per cent of its electricity. All but one of the reactors will be retired by 2023. Unlike Germany and Japan, the UK intends to build a new generation of nuclear plants from about 2018.
More InfoHistorically, indigenous British people were thought to be descended from the various ethnic groups that settled there before the 12th century: the Celts, Romans, Anglo-Saxons, Norse and the Normans. Welsh people could be the oldest ethnic group in the UK. A 2006 genetic study shows that more than 50 per cent of England's gene pool contains Germanic Y chromosomes. Another 2005 genetic analysis indicates that "about 75 per cent of the traceable ancestors of the modern British population had arrived in the British isles by about 6,200 years ago, at the start of the British Neolithic or Stone Age", and that the British broadly share a common ancestry with the Basque people.
More InfoEngland and Scotland were leading centres of the Scientific Revolution from the 17th century. The United Kingdom led the Industrial Revolution from the 18th century, and has continued to produce scientists and engineers credited with important advances. Major theorists from the 17th and 18th centuries include Isaac Newton, whose laws of motion and illumination of gravity have been seen as a keystone of modern science; from the 19th century Charles Darwin, whose theory of evolution by natural selection was fundamental to the development of modern biology, and James Clerk Maxwell, who formulated classical electromagnetic theory; and more recently Stephen Hawking, who advanced major theories in the fields of cosmology, quantum gravity and the investigation of black holes.
