Energy in Denmark

This article describes energy and electricity production, consumption, import and export in Denmark.
Denmark ranks as number 32 in the world among net exporters of crude oil.

Denmark has considerable sources of oil and natural gas in the North Sea and ranks as number 32 in the world among net exporters of crude oil.[1] Denmark expects to be self-sufficient with oil until 2050.[2] However, gas resources are expected to decline, and production may decline below consumption in 2020, making imports necessary.[3] A large but decreasing proportion[4] of electricity is produced from coal and nuclear energy imports,[5] while wind turbines supply the equivalent of about 42% of electricity demand by 2015 (see Wind power in Denmark).[6][7]

In February 2011 the Danish government announced the "Energy Strategy 2050" with the aim to be fully independent of fossil fuels by 2050,[8] and a new government repeated the goal in 2015 despite public scepticism.[9] The European Renewables Directive set a mandatory target at 20% share of energy from renewable sources by 2020 (EU combined).[10][11] In 2012 the Danish government adopted a plan to increase the share of electricity production from wind to 50% by 2020,[12][13] and to 84% in 2035.[14]

Denmark's electrical grid is connected by transmission lines to other European countries,[15] and had (according to the World Economic Forum) the best energy security in the EU in 2013[16] although this had fallen to third in the EU by 2014.[17]

History

In 1972, 92% of Denmark's energy consumption came from imported oil.[18] The 1973 oil crisis forced Denmark to rethink its energy policy; in 1978 coal contributed 18%, and the Tvind wind turbine was made, along with the creation of a wind turbine industry.[19] The 1979 energy crisis pushed further change, and in 1984 the North Sea natural gas projects began.[20] The North Sea production of oil and gas made Denmark self-sufficient in 1997,[21] peaking in 2005,[22] and was no longer self-sufficient by 2013.[23]

The year 2014 was the warmest on record in Denmark, with the lowest number of degree days in history. A normal year has 2,906 while 2014 saw only 2,100 degree days.[24] Since 2000, Denmark has increased Gross National Product and decreased energy consumption.[25]

Minor taxes are called "Compulsory storage fee" and "NOx tax". Carbon dioxide tax is 0.09 DKK/kWh for electricity. Fossil fuels are taxed at about 90 DKK/ton CO2.[28]

Energy taxes contributed 34 billion DKK in 2015, about 12% of taxing revenue.[29] The money is a considerable income for the state, and changing the composition of the taxes towards a "greener" mix is difficult. According to a government official, the majority of taxes are not based on environment concerns,[30] in contrast to the DKK 5 billion per year in PSO-money for cleaner energy, paid by electricity consumers to producers of clean electricity. These tolls are not available for government consumption.[31]

Energy sources

Coal

Fossil fuel consumption in Denmark.
Main article: Coal power in Denmark

Coal power provided 48.0% of the electricity and 22.0% of the heat in district heating in Denmark in 2008; and in total provided 21.6% of total energy consumption (187PJ out of 864PJ).[32] The coal is mainly imported from outside Europe.[33] Consumption of coal was more than halved over the 10 years between 2004-2014.[4]

Oil

Production

The production of crude oil fell from 523 PJ in 2010 to 470 PJ in 2011. As of May 2014, Denmark produced an average of 172 kbpd.[34]

Consumption

Consumption fell from 315 to 306 PJ during 2011.[35] Official statistics estimate 231,000 residences heated by oil in 2014 (down from 328,000 in 2013), but only 87,000 actually purchased oil during 2014.[36]

Natural gas

The production of natural gas fell from 307 PJ in 2010 to 265 PJ in 2011. Consumption fell from 187 to 157 PJ.[35]

CO2 emissions from energy production fell from 49.4 to 44.3 million tons, from 2010 to 2011,[35] a decline of 10%.[37]

Biomass

Denmark consumed 2.1 million tonnes of wood pellets in 2014, expected to increase by 1.2 million tonnes as more coal is replaced. They are mainly imported from the Baltic states and Russia. Denmark also burns wood chips and straw, mostly for heating.[38]

Nuclear Energy

The production of nuclear energy has been banned in Denmark since 1985. In 2014 and 2015, (imported) nuclear power was 3-4% of electricity consumption in Denmark.[39] An average of 10% of domestic energy consumption comes from nuclear power imports from neighboring countries Sweden and Germany.[40] In 2011, with imports of 2.9 TWh from Germany and 5.2 TWh from Sweden, about 3.5TWh used was nuclear – nearly 11% of total final consumption. This fluctuates year to year, mainly due to NordPool prices, and Energinet.dk analysis showed 1% nuclear in 2010, 7% in 2011 and 14% in 2012.[40]

Solar

Denmark had 790 MW of photovoltaic capacity in late 2015,[41] and already reached its year 2020 governmental goal of installing 200 MW in 2012.[42] As of 2013, the total PV capacity from 90,000 private installations amounts to 500 MW.[43] Danish energy sector players estimate that this development will result in 1000 MW by 2020 and 3400 MW by 2030.[42]

Solar heating is installed in some homes,[44] and also used in district heating.[45]

Geothermal

Denmark has two geothermal district heating plants, one in Thisted started in 1988, and one in Copenhagen started in 2005.[46][47] They produce no electricity.

Electricity

The electricity sector relies on fossil, nuclear and renewable energy: wind power, biogas, biomass and waste. No hydro power is produced domestically and other countries' hydro and thermal power is used for buffering Denmark's renewable generation. The average consumption of electricity per person was 0.8 GWh less than EU 15 average in 2008. Denmark invested in the wind power development in the 1970s and has been the top wind power country of the world ever since. Danish consumption of wind electricity has been highest in the world per person: 1,218 kWh in 2009. Denmark produced more wind power per person in 2009 than Spain or the UK produced nuclear power.

Denmark has mediocre electricity costs (including about DKK 5 billion in costs for cleaner energy)[31] in EU for industries at 9eurocent/kWh,[48][49][50][51] but general taxes increase the household price to the highest in Europe at 31eurocent/kWh.[48][52]

Transmission costs are around 1c/kWh, and support regimes cost 2½c/kWh in 2014.[53]

Wind power

Main article: Wind power in Denmark

Wind provided 39% of the electricity generated in Denmark in 2014,[7][54][55] and 42.1% of Denmark's total electricity consumption in 2015.[6][56] Denmark is a long-time leader in wind energy, and as of May 2011 Denmark derives 3.1 percent of its Gross Domestic Product from renewable energy technology and energy efficiency, or around €6.5 billion ($9.4 billion).[57][58]

To encourage investment in wind power, families were offered a tax exemption for generating their own electricity within their own or an adjoining commune. While this could involve purchasing a turbine outright, more often families purchased shares in wind turbine cooperatives which in turn invested in community wind turbines. By 2004 over 150,000 Danes were either members of cooperatives or owned turbines, and about 5,500 turbines had been installed, although with greater private sector involvement the proportion owned by cooperatives had fallen to 75%.

District heating

Danish district heating plants use 100 Petajoule/year,[59] mostly waste heat from thermal power plants burning coal, natural gas and biomass, but a small part of this consumption is from electrode boilers[60] or heat pumps.[61][62] Expansion of wind powered district heating is calculated to be economically efficient without taxes.[63][64] The peak thermal load of district heating in Copenhagen is 2.5 GWth, and simulations suggest a potential heat pump would run 3,500 load-hours per year using sewage water as the heat reservoir.[65]

In 2013, Denmark imported 158,000 ton garbage for incineration in 10 district heating plants,[66] increasing to 323,963 ton in 20 plants in 2015, about 10% of burnt waste.[67]

The pipe heat loss is 17%, at a value of DKK 150 million. New pipes have a heat loss of 6.5%. There are 60,000 km of pipes, serving 1.6 million households.[68] Several towns use central solar heating, some with storage.[45][69]

Transport

Main article: Transport in Denmark

Denmark aims to focus on intelligent battery systems (V2G) and plug-in vehicles in the transport sector.[70]

Tax revenue from vehicles was 28 billion DKK in 2014.[29]

Cities

Copenhagen has a target to be carbon-neutral by 2025,[71] and has burned more biomass and less coal during 2004-2014.[72]

Aarhus aims to be carbon-neutral by 2030.[73]
