According to data from the Danish Energy Agency, Denmark's consumption of renewable energy increased by 3% in 2023, driven mainly by a significant 35% rise in solar energy usage. The consumption of biogas, ambient heat, firewood, and wind energy also contributed to this overall increase. However, the use of wood pellets declined by 3.2 PJ, or nearly 7%.

The domestic production of renewable energy grew by 5.3%, accounting for more than half of the total domestic energy production, similar to 2022. Additionally, renewable energy sources supplied 82.1% of the domestic electricity supply in 2023, up from 81.4% in 2022.

Wind power contributed 53.8% of the electricity production, while biomass accounted for 16.4%, solar energy provided 9.3%, and biogas made up the remaining 2.5%.

At the same time, Denmark's actual consumption of fossil fuels decreased by 7.7% in 2023, largely due to a significant 36% drop in coal consumption—the lowest level recorded in the 50-year history of energy statistics. Natural gas consumption was reduced by over 5%, and oil consumption fell by nearly 4%. Total energy consumption decreased by 2.2% to 667 PJ, while gross energy consumption, adjusted for climate variations and electricity trade, fell by 0.6%.

As a result of reduced fossil fuel consumption, Denmark's actual CO2 emissions from energy consumption fell by 2.1 million tons in 2023 to 25.8 million tons, corresponding to a 7.6% decrease compared to 2022. Since 1990, actual CO2 emissions from energy consumption have declined by 51.3%. When emissions are adjusted for fuel consumption related to electricity trade and climate variations, CO2 emissions fell by 5.4% to 27.3 million tons.

The final report on Denmark's total greenhouse gas emissions for 2023 is expected to be published by DCE – National Center for Environment and Energy in the spring of 2025.
