Denmark seeks to lead the global fight against climate change, primarily through the development of technologies for the use of renewable energy, including wind plays an important role.
The origin of the Danish search a more “green” can be traced to the Arab-Israeli war of October 1973 and subsequent international oil crisis.
At that time, Denmark depended on more than 90 percent of imported oil, and the crisis forced the country to take a 180 degree shift in their patterns of energy production and consumption, with the application of severe tax and a rigorous regulatory framework .
Successive Danish governments also encouraged investment in research and development of renewable energy sources like wind and second-generation biofuels.
The result of these measures is now a multibillion dollar industry that provides thousands of jobs to the national economy in that period has grown nearly 80 percent while the country has maintained a stable level of energy consumption.
Given the growing evidence of global warming caused by greenhouse gases, and its potentially devastating effects, Denmark has strengthened in recent years its search for ways of sustainable development.
In March 2008, the government appointed a Commission on Climate Change, composed of 10 scientists with special expertise in the fields of climate, agriculture, transportation and economy-with the task of making recommendations on how the country could become independent of fuel fossils.
Electric vehicle with lithium batteries do not emit CO2 or damage the environment if the electricity comes from renewables such as wind, solar photovoltaic and solar thermal or thermal. Wind turbines can supply electricity to electric vehicles in the future will also serve to store and regulate the electricity intermittent wind energy sector.
The Commission presented its findings in September 2010, under which Denmark can gradually reduce their use of oil, natural gas and coal, to completely eliminate these fuels in their energy portfolio by 2050.
The government formally took over the group’s recommendations, which Denmark aspires to become, in a span of four decades, the first fossil fuel free.
It is in pursuit of that goal that wind power plays an increasingly important role. Denmark was a pioneer in this field in the 1970’s, and nearly half of the wind turbines in the world are produced by Danish manufacturers.
In Denmark, wind turbines are always on the horizon, generating more than three thousand megawatts of electricity, or about 20 percent of total consumption in the country-the highest proportion of the world.
Many of these turbines rise more than 100 meters above the ground or on offshore platforms, each with three blades 40 meters long whose ends rotate at over 160 kilometers per hour as high-tech versions of windmills the bucolic Dutch countryside.
The Danes do not seem to mind much the sight of these huge towers, perhaps because some turbines are cooperatively owned by residents, and meeting community needs of its electricity.
Since then, this source of energy is not without its problems, the most obvious of which is the variability of the winds.
On days with little wind, the turbines can remain operational, in which case power plants using different fuels such as agricultural waste, biomass and petroleum products, increase their contribution to the national grid.
By contrast, when the wind is too strong and the turbines generate excess electricity, Denmark is forced to sell the surplus at unfavorable prices to neighboring countries such as Norway and Germany.
However, with the prospect of exhaustion (and therefore more expensive) fossil fuels and the development of technologies for the storage of excess energy, use renewable sources like wind is emerging as an alternative both economically viable and environmentally sustainable .
