Fossil fuels will eventually be depleted, and their use continues to harm the environment. As a result, many nations are now focusing on developing green energy solutions. At a recent science and technology-themed forum, Chinese Academy of Engineering academician He Hejun emphasized that the shift to new energy represents a fundamental transformation in primary energy technology, with significant implications for future economic growth and daily life.
Thomas highlighted the impressive growth of wind power, noting that by 2013, China's wind power capacity had surpassed 13,000 megawatts, placing it second globally after the United States. Meanwhile, Denmark has long been a leader in wind energy. Thomas referred to Denmark as a "wind power hotspot," pointing out that the country was at the forefront of wind power development in the 20th century. By 2011, more than 28% of Denmark’s electricity came from wind, showcasing its early commitment to renewable energy.
In Denmark, there is broad political support for wind energy, with all major parties, including the opposition, backing its expansion. According to Finn Mortensen, executive director of the Danish Green Country Alliance, the nation aims to generate 35% of its energy from renewables—primarily wind—by 2020. This goal reflects a national consensus on sustainable energy.
Although global wind power growth has slowed compared to solar energy, the cost of wind power has been steadily decreasing. Thomas cited a U.S. national laboratory report from August 2012, which showed that wind power plants had a cost of $40 per megawatt and an after-tax price of $62. At $62 per megawatt, this is actually cheaper than most traditional electricity sources.
One of the key goals is to completely phase out fossil fuel dependence by 2050, according to Finn. He also noted that Denmark is not alone in its environmental efforts; many Nordic countries have made significant strides in adopting renewable energy. Sweden, for example, announced in 2006 that it would stop relying on oil as its main energy source within 15 years, aiming to achieve this by around 2020.
These developments highlight a growing global movement toward cleaner, more sustainable energy systems, driven by innovation, policy, and public support.
