Swedish Renewable Energy
Few industrialised countries use as much renewable energy as Sweden. Around one third of the country's energy supplies are based on renewable energy*: Sweden can therefore offer expertise on technology, the environment and financial aspects of all renewable kinds of energy.


Bioenergy
For 25 years bioenergy has been developed rapidly in Sweden. Utilisation has more than doubled, and an industry has grown up around bioenergy.
Biofuels are used in the forestry industry as an important source of fuel for pulp manufacture and in sawmills. Biofuels have also taken over the role as the most important fuel in the production of district heating.


Many Swedish municipalities have invested in biofuel-fired combined heat and power plants to generate both electricity and heating. One internationally recognised example is Vãxjö, which aims to be a municipality with minimum utilisation of fossil fuels.
Technology around biofuels has developed to become largely automated, and with low emissions of undesirable substances.


This also applies to small-scale technology to supply small residential areas, apartment blocks and even down to the level of an individual house. There is tremendous expertise and experience in Sweden in these areas as far as technology, planning and the environment are concerned.


Hydro power
Development of hydro power started in conjunction with the electrification of the country in the late 1880s. Many smaller electricity networks were built in connection with the extension of hydro power.


Extension work did not top until the 1970s. At present there are more than 200 hydro power plants of 10 MW, as well as almost two thousand smaller hydro power plants.
Sweden can thus offer everything from qualified consultancy services to deliveries of complete smaller turbines.


Wind power
Sweden also has good conditions for wind power. Large, open spaces in the south of the country and the mountains in the north, and not least of all 386,000 km of coastal areas, make wind power an attractive source of energy. Wind power can also be co-ordinated with hydro power, i.e. the variations in the wind can be evened out with the aid of adjustable hydro power.


Today Sweden already produces 600 GWh electricity using wind power, a figure that is expected to increase relatively strongly in the next few years, especially if the national target of 10 TWh wind power is reached.
In Sweden there is expertise in technology, planning, financing and generation of wind power.


Geothermal power
One city in Sweden - Lund - bases part of its district heating supply on geothermal heat. Investigations are under way in both Malmö and Lund into extended production using geothermal power.


Solar energy
For many years there has been significant investment in solar cells and thermal solar heat. At the University of Uppsala's Ångström Solar Center internationally acknowledged research is taking place into thin-film solar cells.
Many small Swedish companies are already exporting everything from ready-to-use solar panels to components for solar panels.


* Does not take into account waste heat losses from nuclear power. Including these, the proportion of renewable energy is approx. 25 per cent.

Jah tkole sem reku. Mamo v Sloveniji 2 Giga Watta elektrocentral?

Klinc mamo! Ampak to bi pomenilo 1 kilo Watt moči na piplčka.

Ja?

Hint! Avto vozi eno uro na dan.

Ne porajtej. OwcA recimo, je ufuku 3 (tri) velikostne razrede. Tko da tale drobiž ni pomemben.

Pa denimo, da kila te župe da ene 50 milijonov J, torej da tole 2,5 krat deset na 12 Wattov, če bi zakurli.

Tolk kot ljubo Solnce sije na kako velik kvadrat?

Recimo, da tolk požge na uro, ki je 3600 sekund. Pomeni ... 83 kW.

Ampak ta ocena, se pa ne sklda z močjo motorja. Recimo, da ima povprečen avto nekje okoli 100 konjskih moči, to je ~75 kW. Tu pa je potrebno upoštevati izkoristek, ki končno vrednost dvigne ravno za en velikostni razred, tako da se ujema tudi z mojo (preračunano na dan, tisto je bila vsekakor napaka
