In 2024, Denmark has reached a commendable milestone in its electricity generation by sourcing more than 84% of its electricity from low-carbon sources. A significant portion of this clean electricity comes primarily from wind energy, contributing close to 60% to the total electricity mix. Additionally, solar energy adds almost 11% to the low-carbon mix, while biofuels account for over 14%. Conversely, the reliance on fossil fuels has been significantly reduced to just under 16%, with coal being the predominant fossil source at nearly 10%, followed by gas and oil. Denmark's transition to low-carbon electricity not only supports its own sustainable goals but also positions the country as a net exporter of electricity, aiding neighboring nations in decreasing their fossil fuel emissions. The next challenge for Denmark involves electrifying other economic sectors like transport, heating, and industry, which will necessitate a more substantial supply of green electricity.
To further increase the share of low-carbon electricity generation, Denmark can focus on expanding its existing wind and solar capacities. Given the country's proven track record with wind, it would be advantageous to capitalize on offshore wind potential, thus harnessing Denmark’s geographic advantages. Moreover, with solar power having demonstrated consistent growth, expanding solar installations, particularly in urban and industrial settings, would increase clean energy capacity. Investing in technologies such as energy storage and smart grids can also help integrate more intermittent wind and solar power into the grid, managing demand and supply more effectively. Additionally, considering nuclear power as a dependable low-carbon option could diversify Denmark's clean electricity mix, providing a consistent and reliable energy source to complement the variable nature of wind and solar.
The journey towards low-carbon electricity in Denmark has been marked by consistent and innovative efforts over the years. In the late 1990s and early 2000s, Denmark made substantial investments in wind energy. Notably, there were increments of around 1 to 2 TWh in various years, boosting wind electricity generation. The 2010s witnessed further investment in both wind and biofuels, with an exceptional increase in wind power by 2 TWh in certain years. Most notably, the early 2020s have shown a significant surge in wind and biofuels, accompanied by a steady rise in solar power. However, attention must be paid to some fluctuations, like the drop in biofuels in the last few years. Despite these challenges, Denmark's approach exemplifies how consistent commitment to low-carbon technologies can gradually reshape an energy system, paving the way for a sustainable future.
