From September 2025 through August 2026, low-carbon sources supplied about 64% of Lithuania’s electricity consumption—almost two-thirds of the total. Wind was the largest source, providing about 39%, followed by solar at 12%, while biofuels and hydropower each contributed around 6%. Fossil fuels supplied about 9%, including roughly 6% from gas. Net imports accounted for another quarter of electricity consumption; their generation mix is not specified, so they should not automatically be classified as either clean or fossil electricity.

Is Electricity Growing in Lithuania?

Lithuania’s latest figures remain well below its historical electricity records, although these comparisons alone do not establish whether consumption is currently growing year by year. In 2026, electricity consumption stood at about 4,400 kWh per person, compared with roughly 7,900 kWh in the record year of 1991—a decline of around 3,600 kWh, or 45%. Low-carbon electricity generation reached about 2,800 kWh per person, around 2,000 kWh below its 2003 peak of approximately 4,800 kWh—a shortfall of 42%. These substantial gaps underline the importance of expanding clean electricity generation to support electrification and future demand, including from AI.

Suggestions

Lithuania can build on its existing strengths by expanding wind and solar generation while considering new nuclear capacity. Denmark, where wind supplies about 57% of electricity, offers a relevant regional example for further wind development. Hungary’s solar share of about 22%, compared with Lithuania’s 12%, illustrates the scope for a larger solar contribution in a European setting. For nuclear electricity, nearby Finland and Sweden provide useful examples, generating about 38% and 25% of their electricity from nuclear respectively, while Slovakia reaches roughly two-thirds. Learning from these regions could help Lithuania develop a larger, diversified low-carbon electricity supply and reduce reliance on fossil generation, with its associated climate change and air pollution.

History

Lithuania’s low-carbon electricity history shows strong nuclear growth followed by substantial setbacks and, more recently, gains in wind and solar. Nuclear generation increased by a combined 7.4 TWh in 1988–1989. The 1990s were volatile: declines totaling 9.4 TWh in 1992–1994 were followed by a 6.2 TWh recovery in 1995–1996, then further alternating gains and losses through 1999. After another decline in 2000, nuclear output rose by a combined 7 TWh in 2001–2003. The subsequent losses of 4.8 TWh in 2005 and 1.7 TWh in 2006 were particularly disappointing setbacks for clean electricity supply; gains in 2007 and 2009 only partly offset them. More recently, wind added 1 TWh in 2023 and solar added 1.1 TWh in 2026—welcome progress that Lithuania should build on through sustained clean electricity expansion.
