Copenhagen Central Station with S-Trains.
Significant investment has been made in building road and rail links between Copenhagen and Malmö, Sweden (the Øresund Bridge), and between Zealand and Funen (the Great Belt Fixed Link). The Copenhagen Malmö Port was also formed between the two cities as the common port for the cities of both nations.
The main railway operator is Danske Statsbaner (Danish State Railways) for passenger services and DB Schenker Rail for freight trains. Therailway tracks are maintained by Banedanmark. Copenhagen has a small Metro system, the Copenhagen Metro and the greater Copenhagen area has an extensive electrified suburban railway network, the S-train.
Private vehicles are increasingly used as a means of transport. Because of the high registration tax (180%) and VAT (25%), and the world's highest income tax rate, new cars are very expensive. The purpose of the tax is to discourage car ownership. Whether a smaller fleet of aging cars is better than a larger fleet of modern cars is a matter for debate, however as the car fleet has increased by 45% over the last 30 years the effect of high taxation on the fleet size seems small. The motorway network now covers 1,111 km. In 2007, an attempt was made by the government to favour environmentally friendly cars by slightly reducing taxes on high mileage vehicles. However, this has had little effect, and in 2008 Denmark experienced an increase in the import of fuel inefficient old cars (mostly older than 10 years), primarily from Germany as their costs including taxes keeps these cars within the budget of many Danes.
Denmark is in a strong position in terms of integrating fluctuating and unpredictable energy sources such as wind power in the grid. It is this knowledge that Denmark now aims to exploit in the transport sector by focusing on intelligent battery systems (V2G) and plug-in vehicles.
Denmark has invested heavily in windfarms.
Denmark is a long time leader in wind energy and a prominent exporter of wind turbines, and as of May 2011 Denmark derives 3.1% of its gross domestic product from renewable (clean) energy technology and energy efficiency, or around €6.5 billion ($9.4 billion). It has integrated fluctuating and unpredictable energy sources such as wind power into the grid. Denmark now aims to focus on intelligent battery systems (V2G) and plug-in vehicles in the transport sector. Energinet.dk is the Danish national transmission system operator for electricity and natural gas.
Oil and Natural Gas
Denmark has considerable sources of oil and natural gas in the North Sea and ranks as number 32 in the world among net exporters ofcrude oil. Esbjerg is Denmark's main city for the oil and gas industry, this is because of its ideal location close to the north sea, which is where Denmark's Oil and gas deposits are found. Companies like Maersk, Ramboll, Stimwell Services, ABB, Schlumberger, COWI and Atkins all have offshore related activities in the city.
