Denmark levies high taxes on gasoline and automobiles - cars have a sales tax of 100%, and the price of a gallon of gasoline is nearly 50% taxes. This keeps the volume of vehicles, and carbon emissions, low. The majority of workers in this relatively small country of 5.5 million commute by bicycle, public transport, or walking. Denmark has more oil in its energy mix than the United States, though it comes from the North Sea oil patch and none from the Middle East. In 2011 the Danish government presented a strategy to be fossil-fuel free by the year 2050; currently they produce 20% of electricity from wind power.
