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.
Jamaica (i/dʒəˈmeɪkə/) is an island country situated in the Caribbean Sea, comprising the third-largest island of the Greater Antilles. The island, 10,990 square kilometres (4,240 sq mi) in area, lies about 145 kilometres (90 mi) south of Cuba, and 191 kilometres (119 mi) west of Hispaniola, the island containing the nation-states of Haiti and the Dominican Republic. Jamaica is the fifth-largest island country in the Caribbean.
Previously inhabited by the indigenous Arawak and Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Named Santiago, it remained a possession of Spain until 1655, when England (later Great Britain) conquered the island and renamed it Jamaica. Under British rule, Jamaica became a leading sugar exporter, with its plantation economy highly dependent on slaves imported from Africa, followed later by Chinese and Indian indentured labour. All slaves were fully emancipated in 1838, with independence from the United Kingdom achieved on 6 August 1962.
"Jamaica" is a song by Canadian rock group Bachman–Turner Overdrive that appears on the 1979 album Rock n' Roll Nights. It features Jim Clench on lead vocals. It was written by well-known songwriter Jim Vallance. It was released as a single but did not chart. The song, along with "Heartaches," was played live on American Bandstand in February 1979 to support the Rock n' Roll Nights album release.
Using different lyrics, Rick Springfield remade the song under the title "Kristina" on his 1982 album Success Hasn't Spoiled Me Yet.
Jamaica : A Novel (2007) is a novel by Australian author Malcolm Knox. It won the Colin Roderick Award in 2007, and was shortlisted for the Fiction category of the 2008 Prime Minister's Literary Awards.
A group of 6 Australian friends - white, middle-aged males - combine to compete in a marathon relay swim in treacherous waters off Jamaica. But even before the race begins fractures appear in the relationships, with drug-taking, hidden secrets and personal crises coming to dominate.
