As of 2024, Lithuania's electricity consumption is primarily sourced from low-carbon options, making up more than three-quarters of its total electricity generation. Wind energy is the dominant clean energy contributor, supplying just over a third, while hydropower accounts for nearly a fifth of the electricity mix. Solar energy also plays a significant role, producing approximately 15% of the electricity. Meanwhile, net imports, which might include clean energy sources, make up close to 12%. The fossil fuel contribution, represented entirely by gas, is relatively small at less than 9%, pointing to Lithuania's strong commitment to low-carbon energy in reducing climate change impacts and air pollution.
To further elevate its low-carbon electricity generation, Lithuania has the opportunity to expand its existing wind and solar infrastructure which already significantly contribute to the power grid. Emulating successful international practices, Lithuania could learn from Denmark, which derives a massive 59% of its electricity from wind energy. Additionally, countries like Slovakia and Ukraine demonstrate effective nuclear energy integration, with nuclear power accounting for 60% and 55% of their respective electricity needs. Nuclear power can provide a stable and continuous clean energy source, and Lithuania should consider revitalizing or expanding its nuclear energy capacities for sustainable growth.
The history of low-carbon electricity in Lithuania, particularly nuclear, has seen dramatic shifts over the decades. The late 1980s marked a period of growth, with nuclear energy contributions rising by 3.6 TWh in 1988 and 3.8 TWh in 1989. However, the early 1990s saw significant declines, with sharp reductions in 1992 and 1993 totaling nearly 5 TWh. There was a resurgence in the mid-90s as nuclear energy generation increased, notably in 1995 and 1996. But from 1999 to the mid-2000s, erratic changes culminated in a severe drop in 2005. More recently, Lithuania has turned back towards clean energy expansion, notably increasing wind and hydro contributions in 2023 and 2024, showing promising strides toward achieving a sustainable electricity future.
