Helsinki ( /ˈhɛlsɪŋki/ HEL-sink-ee or /hɛlˈsɪŋki/ ( listen ) hel-SINK-ee , Finnish : [ ˈhelsiŋki ] ( listen ) ; Swedish : Helsingfors [ hɛlsɪŋˈfɔʂː ] ( listen ) , Finland Swedish : [ helsiŋˈforsː ] ( listen ) ) is the capital and most populous city of Finland . Located on the shore of the Gulf of Finland , it is the seat of the region of Uusimaa in southern Finland , and has a population of 650,058 . The city 's urban area has a population of 1,268,296 , making it by far the most populous urban area in Finland as well as the country 's most important center for politics , education , finance , culture , and research . Helsinki is located 80 kilometres ( 50 mi ) north of Tallinn , Estonia , 400 km ( 250 mi ) east of Stockholm , Sweden , and 300 km ( 190 mi ) west of Saint Petersburg , Russia . It has close historical ties with these three cities . Together with the cities of Espoo , Vantaa , and Kauniainen , and surrounding commuter towns , Helsinki forms the Greater Helsinki metropolitan area , which has a population of nearly 1.5 million . Often considered to be Finland 's only metropolis , it is the world 's northernmost metro area with over one million people as well as the northernmost capital of an EU member state . After Stockholm and Oslo , Helsinki is the third largest municipality in the Nordic countries . Swedish and Finnish are both official languages . The city is served by the international Helsinki Airport , located in the neighboring city of Vantaa , with frequent service to many destinations in Europe and Asia . Helsinki was the World Design Capital for 2012 , the venue for the 1952 Summer Olympics , and the host of the 52nd Eurovision Song Contest in 2007 . Helsinki has one of the highest urban standards of living in the world .
Coal is a combustible black or brownish-black sedimentary rock , formed as rock strata called coal seams . Coal is mostly carbon with variable amounts of other elements ; chiefly hydrogen , sulfur , oxygen , and nitrogen . Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years . Vast deposits of coal originate in former wetlands - called coal forests - that covered much of the Earth 's tropical land areas during the late Carboniferous ( Pennsylvanian ) and Permian times . As a fossil fuel burned for heat , coal supplies about a quarter of the world 's primary energy and two-fifths of its electricity . Some iron and steel making and other industrial processes burn coal . The extraction and use of coal causes many premature deaths and much illness . The coal industry damages the environment , including by climate change as it is the largest anthropogenic source of carbon dioxide , 14 gigatonne ( Gt ) in 2016 , which is 40% of the total fossil fuel emissions and almost 25% of total global greenhouse gas emissions . As part of the worldwide energy transition many countries have stopped using or use less coal , and the UN Secretary General has asked governments to stop building new coal plants by 2020 . To meet the Paris Agreement target of keeping global warming to well below 2 °C ( 3.6 °F ) coal use needs to halve from 2020 to 2030 . The largest consumer and importer of coal is China . China mines almost half the world 's coal , followed by India with about a tenth .
Fuel oil ( also known as heavy oil , marine fuel or furnace oil ) is a fraction obtained from petroleum distillation , either as a distillate or a residue . In general terms , fuel oil is any liquid fuel that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power , except oils having a flash point of approximately 42 °C ( 108 °F ) and oils burned in cotton or wool-wick burners . Fuel oil is made of long hydrocarbon chains , particularly alkanes , cycloalkanes , and aromatics . The term fuel oil is also used in a stricter sense to refer only to the heaviest commercial fuel that can be obtained from crude oil , i.e. , heavier than gasoline and naphtha . Small molecules like those in propane , naphtha , gasoline for cars , and jet fuel have relatively low boiling points , and they are removed at the start of the fractional distillation process . Heavier petroleum products like diesel fuel and lubricating oil are much less volatile and distill out more slowly , while bunker oil is literally the bottom of the barrel ; in oil distilling , the only things denser than bunker fuel are carbon black feedstock and bituminous residue ( asphalt ) , which is used for paving roads and sealing roofs .
Kristinestad ( Swedish : [ krɪsˈtîːnɛˌstɑːd ] , Finland Swedish : [ krisˈtiːneˌstɑːd ] ; Finnish : Kristiinankaupunki [ ˈkristiːnɑŋˌkɑu̯puŋki ] ) is a town and a municipality in Finland . It is located in the western part of Finland on the shore of the Bothnian Sea . The population of Kristinestad is 6,599 ( 31 January 2019 ) and the municipality covers an area of 682.53 km2 ( 263.53 sq mi ) ( excluding sea areas ) of which 14.66 km2 ( 5.66 sq mi ) is inland water ( 1 January 2018 ) . The population density is 9.67/km2 ( 25.0/sq mi ) . The population is bilingual with a majority speaking Swedish ( 57% ) and the minority Finnish ( 42% ) . The town was chartered in 1649 by Per Brahe the Younger at Koppö island and is named for Queen Christina of Sweden . Kristinestad is known for its old town with low wooden houses and narrow alleys . In April , 2011 , Kristinestad became Finland 's first Cittaslow community .
Lahti ( Finnish pronunciation : [ ˈlɑhti ] ; Swedish : Lahtis ) is a city and municipality in Finland . Lahti is the capital of the region of Päijänne Tavastia ( Päijät-Häme ) . It is situated on a bay at the southern end of lake Vesijärvi about 100 kilometres ( 60 mi ) north-east of the capital Helsinki . In English , the Finnish word Lahti literally means bay . The Lahti region is growing and is one of the main economic hubs of Finland . The coat of arms of the city depicts a train wheel surrounded by flames .
Natural gas ( also called fossil gas ) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane , but commonly including varying amounts of other higher alkanes , and sometimes a small percentage of carbon dioxide , nitrogen , hydrogen sulfide , or helium . It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years . The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas . Natural gas is a non-renewable hydrocarbon used as a source of energy for heating , cooking , and electricity generation . It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals . Natural gas has a complicated effect on climate change ; it itself is a greenhouse gas , and it releases carbon dioxide when burned . However , natural gas use often supplants coal use , which is far more environmentally damaging , leading to lower net carbon dioxide emissions in countries such as the United States . Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates . Petroleum is another resource and fossil fuel found close to and with natural gas . Most natural gas was created over time by two mechanisms : biogenic and thermogenic . Biogenic gas is created by methanogenic organisms in marshes , bogs , landfills , and shallow sediments . Deeper in the earth , at greater temperature and pressure , thermogenic gas is created from buried organic material .
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen ( anaerobically ) , primarily consisting of methane and carbon dioxide . Biogas can be produced from raw materials such as agricultural waste , manure , municipal waste , plant material , sewage , green waste or food waste . Biogas is a renewable energy source . In India , it is also known as Gobar Gas . Biogas is produced by anaerobic digestion with methanogen or anaerobic organisms , which digest material inside a closed system , or fermentation of biodegradable materials . This closed system is called an anaerobic digester , biodigester or a bioreactor . Biogas is primarily methane ( CH4 ) and carbon dioxide ( CO2 ) and may have small amounts of hydrogen sulfide ( H2S ) , moisture and siloxanes . The gases methane , hydrogen , and carbon monoxide ( CO ) can be combusted or oxidized with oxygen . This energy release allows biogas to be used as a fuel ; it can be used for any heating purpose , such as cooking . It can also be used in a gas engine to convert the energy in the gas into electricity and heat . Biogas can be compressed , the same way as natural gas is compressed to CNG , and used to power motor vehicles . In the United Kingdom , for example , biogas is estimated to have the potential to replace around 17% of vehicle fuel .
Tampere ( /ˈtæmpəreɪ/ , also US : /ˈtɑːm-/ , Finnish : [ ˈtɑmpere ] ( listen ) ; Swedish : Tammerfors [ tɑmːærˈforsː ] ( listen ) ) is a city in Pirkanmaa , southern Finland . It is the most populous inland city in the Nordic countries .

Peat ( /piːt/ ) , also known as turf ( /tɜːrf/ ) , is an accumulation of partially decayed vegetation or organic matter . It is unique to natural areas called peatlands , bogs , mires , moors , or muskegs . The peatland ecosystem is the most efficient carbon sink on the planet , because peatland plants capture CO2 naturally released from the peat , maintaining an equilibrium . In natural peatlands , the annual rate of biomass production is greater than the rate of decomposition , but it takes thousands of years for peatlands to develop the deposits of 1.5 to 2.3 m [ 4.9 to 7.5 ft ] , which is the average depth of the boreal [ northern ] peatlands . Sphagnum moss , also called peat moss , is one of the most common components in peat , although many other plants can contribute . The biological features of Sphagnum mosses act to create a habitat aiding peat formation , a phenomenon termed 'habitat manipulation ' . Soils consisting primarily of peat are known as histosols . Peat forms in wetland conditions , where flooding or stagnant water obstructs the flow of oxygen from the atmosphere , slowing the rate of decomposition . Peatlands , particularly bogs , are the primary source of peat , although less-common wetlands including fens , pocosins , and peat swamp forests also deposit peat . Landscapes covered in peat are home to specific kinds of plants including Sphagnum moss , ericaceous shrubs , and sedges ( see bog for more information on this aspect of peat ) . Because organic matter accumulates over thousands of years , peat deposits provide records of past vegetation and climate by preserving plant remains , such as pollen . This allows the reconstruction of past environments and study changes in land use .
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants . It is an organic material - a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression . Wood is sometimes defined as only the secondary xylem in the stems of trees , or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs . [ citation needed ] In a living tree it performs a support function , enabling woody plants to grow large or to stand up by themselves . It also conveys water and nutrients between the leaves , other growing tissues , and the roots . Wood may also refer to other plant materials with comparable properties , and to material engineered from wood , or wood chips or fiber . Wood has been used for thousands of years for fuel , as a construction material , for making tools and weapons , furniture and paper . More recently it emerged as a feedstock for the production of purified cellulose and its derivatives , such as cellophane and cellulose acetate . As of 2005 , the growing stock of forests worldwide was about 434 billion cubic meters , 47% of which was commercial . As an abundant , carbon-neutral renewable resource , woody materials have been of intense interest as a source of renewable energy . In 1991 approximately 3.5 billion cubic meters of wood were harvested . Dominant uses were for furniture and building construction .

It is a component of the Euro Stoxx 50 stock market index . The company has operated in various industries over the past 150 years . It was founded as a pulp mill and had long been associated with rubber and cables , but since the 1990s has focused on large-scale telecommunications infrastructures , technology development , and licensing . Nokia is a major contributor to the mobile telephony industry , having assisted in the development of the GSM , 3G and LTE standards ( and currently in 5G ) , and was once the largest worldwide vendor of mobile phones and smartphones . After a partnership with Microsoft and subsequent market struggles , its mobile phone business was bought by Microsoft , creating Microsoft Mobile as its successor in 2014 . After the sale , Nokia began to focus more extensively on its telecommunications infrastructure business and on Internet of things technologies , marked by the divestiture of its Here mapping division and the acquisition of Alcatel-Lucent , including its Bell Labs research organization . The company then also experimented with virtual reality and digital health , the latter through the purchase of Withings .
