Energy conservationEnergy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings.
Climate changeIn common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane.
Embodied energyEmbodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy was incorporated or 'embodied' in the product itself. The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in deciding whether a product contributes to or mitigates global warming.
YurtA yurt (from the Turkic languages) or ger (Mongolian) is a portable, round tent covered and insulated with skins or felt and traditionally used as a dwelling by several distinct nomadic groups in the steppes and mountains of Inner Asia. The structure consists of a flexible angled assembly or latticework of wood or bamboo for walls, a door frame, ribs (poles, rafters), and a wheel (crown, compression ring) possibly steam-bent as a roof. The roof structure is sometimes self-supporting, but large yurts may have interior posts supporting the crown.
TranshumanceTranshumance is a type of pastoralism or nomadism, a seasonal movement of livestock between fixed summer and winter pastures. In montane regions (vertical transhumance), it implies movement between higher pastures in summer and lower valleys in winter. Herders have a permanent home, typically in valleys. Generally only the herds travel, with a certain number of people necessary to tend them, while the main population stays at the base. In contrast, horizontal transhumance is more susceptible to being disrupted by climatic, economic, or political change.
BuryatsThe Buryats (Buryaad, ᠪᠣᠷᠢᠶᠠᠳ; Buriad) are a Mongolic ethnic group native to southeastern Siberia who speak the Buryat language. They are one of the two largest indigenous groups in Siberia, the other being the Yakuts. The majority of the Buryats today live in their titular homeland, the Republic of Buryatia, a federal subject of Russia which sprawls along the southern coast and partially straddles Lake Baikal.
Zero carbon housingZero-carbon housing is a term used to describe a house that does not emit greenhouse gasses, specifically carbon dioxide (CO2), into the atmosphere. Homes release greenhouse gases through burning fossil fuels in order to provide heat, or even while cooking on a gas stove. A zero carbon house can be achieved by either building or renovating a home to be very energy efficient and for its energy consumption to be from non-emitting sources, for example electricity.
Climate change scenarioClimate change scenarios or socioeconomic scenarios are projections of future greenhouse gas (GHG) emissions used by analysts to assess future vulnerability to climate change. Scenarios and pathways are created by scientists to survey any long term routes and explore the effectiveness of mitigation and helps us understand what the future may hold this will allow us to envision the future of human environment system. Producing scenarios requires estimates of future population levels, economic activity, the structure of governance, social values, and patterns of technological change.
BulgarsThe Bulgars (also Bulghars, Bulgari, Bolgars, Bolghars, Bolgari, Proto-Bulgarians) were Turkic semi-nomadic warrior tribes that flourished in the Pontic–Caspian steppe and the Volga region during the 7th century. They became known as nomadic equestrians in the Volga-Ural region, but some researchers believe that their ethnic roots can be traced to Central Asia. During their westward migration across the Eurasian Steppe, the Bulgar tribes absorbed other tribal groups and cultural influences in a process of ethnogenesis, including Iranic, Finnic and Hunnic tribes.
ScythiansThe Scythians (ˈsɪθiən or ˈsɪðiən) or Scyths (ˈsɪθ, but note Scytho- (ˈsaɪθʊ) in composition) and sometimes also referred to as the Pontic Scythians, were an ancient Eastern Iranic equestrian nomadic people who had migrated during the 9th to 8th centuries BC from Central Asia to the Pontic Steppe in modern-day Ukraine and Southern Russia, where they remained established from the 7th century BC until the 3rd century BC. Skilled in mounted warfare, the Scythians replaced the Agathyrsi and the Cimmerians as the dominant power on the western Eurasian Steppe in the 8th century BC.
