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.

Vietnam (UK /ˌvjɛtˈnæm, -ˈnɑːm/, US i/ˌviːətˈnɑːm, -ˈnæm/;Vietnamese: Việt Nam [viət˨ næm˧]), officially the Socialist Republic of Vietnam (SRV; Vietnamese: Cộng Hòa Xã Hội Chủ Nghĩa Việt Nam ( listen)), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants as of 2014, it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. The name Vietnam translates as "Southern Viet" (synonymous with the much older term Nam Viet); it was first officially adopted in 1802 by Emperor Gia Long, and was adopted again in 1945 with the founding of the Democratic Republic of Vietnam under Ho Chi Minh. The country is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, and Malaysia across the South China Sea to the southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1975.
The Vietnam News Agency (VNA), a governmental agency, is the official state news provider of the Socialist Republic of Vietnam.
As the only news agency of the whole country, the state-run VNA is responsible for publishing official information and documents of the party and state, providing information in service of the party leadership and state management, while collecting and providing news via various forms to the mass media agencies, the public and readers of all kinds, both at home and abroad.
The VNA is headquartered at 5 Lý Thường Kiệt Street, Hanoi, in the National News Centre. The organisation’s southern and central representative offices are located at 120 Nguyễn Thị Minh Khai Street, Hồ Chí Minh City, and 28 Lê Thánh Tông Street, Đà Nẵng .
The VNA is a media complex consisting of 32 affiliates, including news units (five editorial departments and two source news centres), various publication and press bodies (one publishing house and nine newspapers), and multi-media units (a television channel and e-portal), together with five news support centres and two printing, trade and services companies.
Vietnam is the third studio album by Shockabilly, released in 1984 by Fundamental Records. It released on CD as Vietnam/Heaven in 1990.
