COGNITIVE SYSTEMS ENGINEERING LABORATORYSweden – population density (1989)
Half the population of Sweden is concentrated to 3% of the territory.
There is a sharp contrast between the fairly well populated southern third of the country with the three main urban areas of Stockholm, Göteborg and Malmö and the northern two thirds. Here we find the majority of people in the coastal area, along the rivers and a few places inland of old agricultural areas or mining districts.
The geographic pattern of population distribution has been fairly stable through the last 250 years, only that the concentration to urban centres has grown immensely.
Around 30% of Sweden, an area twice as large as Belgium and Netherlands together is virtually uninhabited, although its natural resources, forest and water-power are fully developed.

COGNITIVE SYSTEMS ENGINEERING LABORATORYNuclear power referendum (1980)
Referendum following TMI (1979). Line 1: Close down nuclear power considering energy needs, without endangering employment and public welfare.Line 2: As Line 1, with the proviso that future energy installations must not be privately owned.Line 3: Immediate stop for new plants and dismantling of all NPP within 10 years.
Referendum only advisory for government. 75,6 % voter turnout.Line 1 = 18,9 %.Line 2 = 39,1 %Line 3 = 38,7 %.Government decided that all 12 reactors should be allowed to function for 25 years.Other referenda in Sweden:

Today nuclear power accounts for about 50% of the Swedish electricity production. What do you think should be used to replace nuclear power? (Two most attractive alternatives)

Global warming
Arrhenius, S. (1895). "On the influence of carbonic acid in the air upon the temperature of the ground", Stockholm Physical Society. Based on one year of calculations using equations from Jean Baptiste Fourier.
Predicted that a doubling of CO2 levels would cause a warming of around 5 to 6 °C. This almost exactly mirrors the Intergovernmental Panel on Climate Change's most recent assessment.Global warming predictions were neglected, but Arrhenius received the Nobel Prize in Chemistry 1903 (eletrical conductivity of salt solutions).

District heatingOrigin can be traced to Roman inventions. By the 16th and 17th centuries, fuel conservation, smoke abatement, and safety were large factors in design of heating apparatus, as seen by a 1623 proposal to install district heating in London. Separate boiler plants and underground piping were used by English factories in the 1790s and by 1820 was fairly common. Waste heat from factories was used to warm public baths by the 1830s. The Crystal Palace in London had district heating in 1851, at least two steam district heating systems were built in the USA in 1853.
District heating on a commercial basis came into use in 1877 in New York.
In Sweden, the first municipal district heating system was started at Karlstad in 1948. Further district heating systems were started at Norrköping and Malmö in l95l, Göteborg, Sundbyberg, and Stockholm in 1953, Linköping and Västerås in 1954, Örebro in 1956, and Borås in 1959.
All these district heating systems were planned and built for the purpose of utilizing heat from future CHP-plants. In these 10 pioneer towns, oil-fired CHP-plants were also built during the 50's and the 60's.
In order to promote and discuss issues of common interest, the Swedish District Heating Association was founded in 1949.

Biogas in Sweden
EU target for 2020 corresponds to 7 TWh in Sweden.
About 20 mil. m3 biogas sold in 2002 (0,2 TWh). Linköping largest biogas distributor for vehicles in Europe (3,6 milj. m3 biogas 2002).
Currently around 40 filling stations in Sweden. Target is 100 stations by 2007.

COGNITIVE SYSTEMS ENGINEERING LABORATORYDeregulation (Nordic countries)
Selling electricity:More than 450 companies (of which 130 in Sweden). The five largest (Vattenfall, E.ON/Sydkraft, Fortum, Hafslund and Statkraft) has a 36% market share.
Producing electricityMore than 350 producing companies. The five largest (Vattenfall, E.ON/Sydkraft, Fortum, Statkraft and PVO) have a 57 % market share.
Distribution gridsA total of almost 550 companies. The five largest (Vattenfall, E.ON /Sydkraft, Fortum, Nesa and Hafslund) have a 35% market share. Deregulation began in 1996. It coincided with five years with sufficient water supplies (= RAIN). As a consequence prices dropped to around 10-12 öre/kWh. The following years (2002 and 2003) were very dry, and the effects of that are still tangible. In consequence, the base price of electricity rose to around 30 öre/kWh (spot market)
