Solar energy is radiant light and heat from the Sun harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture and artificial photosynthesis.
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.
Solar Energy is a peer-reviewed scientific journal covering research on solar energy such as photovoltaics and solar heating, but also its indirect usages like wind power or bioenergy. It is published by Elsevier on behalf of the International Solar Energy Society. The editor-in-chief is Yogi Goswami. According to the Journal Citation Reports, the journal has a 2013 impact factor of 3.541.
Amsterdam is a 1998 novel by British writer Ian McEwan, for which he was awarded the 1998 Booker Prize.
Amsterdam is the story of a euthanasia pact between two friends, a composer and a newspaper editor, whose relationship spins into disaster.
The book begins with the funeral of artist Molly Lane. Guests at the funeral include British Foreign Secretary Julian Garmony, newspaper editor Vernon Halliday, and composer Clive Linley. The three share certain attributes: each has a very high opinion of himself, each was at some time Molly's lover, and each regards the dead woman's husband, George, with a mixture of amusement and contempt.
Clive and Vernon muse upon Molly's death. It seems she had some kind of rapid-onset brain disease (not specified) that left her helpless and mad. Neither man can understand her attraction to Julian Garmony, the right-wing Foreign Secretary who is about to challenge his party's leadership.
Clive returns home to continue work on a symphony he has been commissioned to write for the forthcoming millennium. Much of the work is complete, save the crucial signature melody. He resolves to go walking in the Lake District, as this tends to inspire him.
"Amsterdam" is a song by Jacques Brel. It combines a powerful melancholic crescendo with a rich poetic account of the exploits of sailors on shore leave in Amsterdam.
Brel never recorded this for a studio album, and his only version was released on the live album Enregistrement Public à l'Olympia 1964. Despite this, it has been one of his most enduringly popular works. It was one of the songs Mort Shuman translated into English for the Jacques Brel is Alive and Well and Living in Paris musical.
Brel worked on the song at his house overlooking the Mediterranean at Roquebrune-Cap-Martin, the house he shared with Sylvie Rivet, a publicist for Philips; a place she had introduced him to in 1960. "It was the ideal place for him to create, and to indulge his passion for boats and planes. One morning at six o'clock he read the words of Amsterdam to Fernand, a restaurateur who was about to set off fishing for scorpion fish and conger eels for the bouillabaisse. Overcome, Fernand broke out in sobs and cut open some sea urchins to help control his emotion."
Amsterdam is the capital and largest city of the Kingdom of the Netherlands.
