Fossil fuels will eventually be exhausted, and their use has long been a major source of environmental pollution. As a result, many nations are now shifting their focus toward developing sustainable, green energy solutions. At a science and technology-themed forum in September, Chinese Academy of Engineering Academician He Hejun emphasized that the transition to new energy represents a fundamental shift in primary energy technologies, with far-reaching implications for future economic growth and daily life.
Thomas highlighted the impressive growth of wind power, noting that by 2013, China had already surpassed 13,000 megawatts of installed wind capacity, ranking second globally after the United States. Meanwhile, Denmark has long been a global leader in wind energy. Thomas referred to Denmark as a "wind power hub," pointing out that it was at the forefront of wind energy development in the 20th century. By 2011, over 28% of Denmark’s electricity came from wind power, setting a strong example for other countries.
The Danish public has shown widespread support for wind energy, with all major political parties, including the opposition, backing its expansion. Finn Mortensen, executive director of the Danish Green Country Alliance, mentioned that the country aims to generate 35% of its energy from renewable sources—primarily wind—by 2020. This goal reflects a national consensus on sustainability and clean energy.
Although wind power growth has lagged behind solar energy in some regions, the cost of wind energy has been steadily decreasing. According to a U.S. national laboratory report from August, the levelized cost of wind power was around $40 per megawatt in 2012, with an after-tax price of $62. At that rate, wind power is now more cost-competitive than traditional electricity generation methods.
One of the key goals for many countries is to eliminate dependence on fossil fuels by 2050. Finn noted that Denmark is not alone in this effort—several Nordic nations have made significant strides in adopting renewable energy. Sweden, for instance, announced in 2006 that it would phase out oil as its primary energy source within 15 years, aiming to achieve energy independence by 2020. These efforts highlight a growing global commitment to cleaner, more sustainable energy systems.
