Solar energy

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 (journal)

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.

Cambodia (ⁱ/kæmˈboʊdiə/;Khmer: កម្ពុជា, Kampuchea, IPA: [kɑmpuˈciə]), officially known as the Kingdom of Cambodia (Khmer: ព្រះរាជាណាចក្រកម្ពុជា, Preăh Réachéanachâk Kâmpŭchéa, IPA: [ˈprĕəh riəciənaːˈcɑk kɑmpuˈciə]) and once known as the Khmer Empire, is a country located in the southern portion of the Indochina Peninsula in Southeast Asia. Its total landmass is 181,035 square kilometres (69,898 sq mi), bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east, and the Gulf of Thailand to the southwest.

With a population of over 15 million, Cambodia is the 70th most populous country in the world. The official religion is Theravada Buddhism, practised by approximately 95 percent of the population. The country's minority groups include Vietnamese, Chinese, Chams, and 30 hill tribes. The capital and largest city is Phnom Penh, the political, economic, and cultural centre of Cambodia. The kingdom is a constitutional monarchy with Norodom Sihamoni, a monarch chosen by the Royal Throne Council, as head of state. The head of government is Hun Sen, who is currently the longest serving non-royal leader in South East Asia and has ruled Cambodia for over 25 years.

Cambodia (song)

"Cambodia" is the fourth single by British singer Kim Wilde. It was released at the end of 1981; a year in which Wilde had already scored three highly successful hit singles and a best-selling debut album.

The single was another international success, topping the charts in France, Sweden and Switzerland and hitting the Top 10 in several other nations. In France alone it sold one million copies. It was released on the 7" format but also as a 12" single in Germany, although not in a remixed or extended version. The B-side of both releases was an exclusive non-album track called "Watching For Shapes".

"Cambodia" was later included on Wilde's second original album, Select and was followed by a more uptempo, instrumental version of the song with the title "Reprise".

Musically and lyrically, "Cambodia" showed a change in direction for Wilde from the new wave feel of her debut album. The song was mainly synth-driven, with oriental-sounding percussion.
