Umeå Energi
Umeå Energi is an energy company based in the town of Umeå in Sweden. It is responsible for the supply of electricity, along with providing district cooling, district heating as well as broadband services through a subsidiary by the name of UmeNet. History The company was founded in 1887, reportedly due to a conversation between an engineer from London and a Swedish mayor at a wedding. Mayor Rothoff attended the wedding of steam engineer John Frederick Luth and Euphrosyne Selma Helena Grafström from Umeå. Rothoff was so impressed that he left the money to buy a Luth & Rosén steam engine. This power plant was operational in 1892 when 36 arc lights became the first electric lighting in Umeå.Culture UmeaEnergi.se, retrieved 2 June 2014 In 1899 power production became more ecological when a hydro electric power unit was installed at the |
Umeå
Umeå ( , , , locally ; ; ; ; ) is a city in northeast Sweden. It is the seat of Umeå Municipality and the capital of Västerbotten County. Situated on the Ume River, Umeå is the largest Urban areas in Sweden, locality in Norrland and the thirteenth largest in Sweden, with a wider municipal population of 132,235 inhabitants in the beginning of 2023. When Umeå University was established in 1965, growth accelerated, and the amount of housing has doubled in 30 years from 1980 to 2010. , Umeå was gaining around 1,000 inhabitants per year and the municipality plans for having 200,000 inhabitants by 2050. The projection of municipality size in 2050 has, however, been questioned as an overestimation in an independent study. Umeå is a college town, university town and centre of education, technical and medical research in northern Sweden. The two universities located in the city, Umeå University and one of the 3 main branches of Swedish University of Agricultural Sciences, SLU, ...

Baggböle
Baggböle is a small village on the Ume River in northern Sweden, approximately upstream of the city of Umeå. The village was a base for sawing local timber in the nineteenth century, with a sawmill powered by the water of the river rapids close to the village. The sawmill at Baggböle was abandoned towards the end of the 19th century, but was in its heyday the largest water-powered sawmill in Sweden. The operations at the sawmill resulted in a new word in Swedish, ''baggböleri'', a term that originally meant illegal felling of timber in forests belonging to the Crown, but is now a pejorative term for 'reckless deforestation' ( Swedish: ). Today Baggböle is known for Arboretum Norr, an arboretum that has been developed to attract visitors, and develop plants suitable for northern latitudes. History The original sawmill at Baggböle Rapids, which was built in 1813-14, stemmed from a partnership between Johan Unander, Eric Nyberg and Johan Vikner, who obtained permission to build ...

Electric Power Distribution Network Operators In Sweden
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

Seasonal Affective Disorder
Seasonal affective disorder (SAD) is a mood disorder subset in which people who typically have normal mental health throughout most of the year exhibit depressive symptoms at the same time each year. It is commonly, but not always, associated with the reductions or increases in total daily sunlight hours that occur during the winter or summer. Common symptoms include sleeping too much, having little to no energy, and overeating. The condition in the summer can include heightened anxiety.Seasonal affective disorder (SAD): Symptoms MayoClinic.com (September 22, 2011). Retrieved on March 24, 2013. However, there are significant differences in the duration, severity, and symptoms of each individual's experience of SAD. For instance, in a fifth of patients, the disor ...

Light Therapy
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections. Treating skin conditions such as neurodermatitis, psoriasis, acne vulgaris, and eczema with ultraviolet light is called ultraviolet light therapy. Medical uses Nutrient deficiency Vitamin D deficiency Exposure to UV-B light at wavelengths of 290-300 nanometers enables the body to produce vitamin D3 to treat vitamin D3 deficiency. Skin conditions Light therapy treatments for the skin usually involve exposure to ultraviolet light. The exposures can be to a small area of the skin or over the whole body surface, as in a tanning bed. The most common treatment is with narrowband UVB, which has a wavelength of approximately 311–313 nan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cogeneration
Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover otherwise wasted thermal energy for heating. This is also called combined heat and power district heating. Small CHP plants are an example of decentralized energy. By-product heat at moderate temperatures ( can also be used in absorption refrigerators for cooling. The supply of high-temperature heat first drives a gas or steam turbine-powered generator. The resulting low-temperature waste heat is then used for water or space heating. At smaller scales (typically below 1 MW), a gas engine or diesel engine may be used. Cogeneration is also common with geothermal power plants as they often produce relatively low grade heat.

Umeå Town Hall
Umeå Town Hall () was built after the fire in 1888 that burnt the city to the ground. It was erected on the site where the previous town hall (built in the 17th century) had been located and was completed in 1890. The architect was Fredrik Olaus Lindström from Stockholm. In the new urban area development plan Lindström gave the town hall a prominent location next to the river bank, with the main facade facing south over the harbour on the Ume River (which was still navigable at the time, providing the city's main point of access). History First town hall During the 17th century, Umeå only had a few public buildings; the church, the school and the town hall. The town hall was on the north of the Rådhustorget (the Town Hall Square), and housed the judiciary, the city administration and other common functions. The town hall was a single-storey building, equipped with three windows facing the square and with a high hipped gable roof topped with a roof lantern. Seco ...

Ume River
The Ume River (Swedish: ''Ume älv'' or ''Umeälven'') is one of the main rivers in northern Sweden. It is around long, and flows in a south-eastern direction from its source, the lake ''Överuman'' by the Norway, Norwegian border within the Scandinavian mountain range. For large parts, the European route E12, also known as Blå Vägen (Blue Route), follows its path. The river passes through Vindelfjällen Nature Reserve and Storuman, Lake Storuman and drains into the Gulf of Bothnia on Sweden's east coast at the small town of Holmsund, and adjacent to the city of Umeå. Its chief tributary is the Vindel River, which is the biggest tributary river in Sweden. The Ume and Vindel rivers meet at the village of Vännas. At the mouth of the river, where it meets the Gulf of Bothnia, lies Obbolaön (Obbola Island). The island divides the river into two streams just as it runs out into the sea. Early history People have lived in the Ume river valley for at least five thousand years. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Utility
An electric utility, or a power company, is a company in the electric power industry (often a public utility) that engages in electricity generation and distribution of electricity for sale generally in a regulated market. Electric utilities are major providers of energy in most countries. Electric utilities include investor owned, publicly owned, cooperatives, and nationalized entities. They may be engaged in all or only some aspects of the industry. Electricity markets are also considered electric utilities—these entities buy and sell electricity, acting as brokers, but usually do not own or operate generation, transmission, or distribution facilities. Utilities are regulated by local and national authorities. Electric utilities are facing increasing demandsBy Candace Lombardi, CNET.
