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.

Denmark (ⁱ/ˈdɛnmɑːrk/; Danish: Danmark [ˈd̥ænmɑɡ̊]), officially the Kingdom of Denmark is a country in Northern Europe. The southernmost of the Nordic countries, it is southwest of Sweden and south of Norway, and bordered to the south by Germany. Denmark is part of Scandinavia, together with Sweden and Norway. It is a sovereign state that comprises Denmark and two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland. Denmark proper has an area of 42,924 square kilometres (16,573 sq mi), and a population of 5,707,251 in January 2016. The country consists of a peninsula – Jutland – and an archipelago of 443 named islands, of which around 70 are inhabited. The islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate.

Ø is a piece of land in the valley of the Nørreå in the eastern part of Jutland, Denmark. Its name means island (ø in the Danish language) and probably comes from the island-like approach to this piece of land, although it is completely landlocked and surrounded by meadows.

Ø is famous among lexicographers for the extreme brevity of its name: the single letter Øand for the people there.

Danmark (islet)

Danmark (English: Denmark) is an islet located near Sandvika in the Municipality of Bærum, Norway.

Whilst the original meaning is not exactly verified, the name of the islet reflects Norwegians' (friendly) joking with the relatively small geographical size of Denmark proper. Alike Denmark, this islet is flat, small, and located oversea south of Bærum. The name predates 1814, when the personal union known as Denmark–Norway was dissolved. In a sale of land in the 1780s, it was mentioned that the sale included 'a little island called Denmark' (Danish: en lille ø kaldet Danmark).
