Latvia’s future energy balance

Renewable resources that are available in Latvia include water, wind and solar energy, as well as different types of biomass – fuel wood, straw, rape. Biogas from decomposition processes of organic substances in waste management has been used as well. In 2003, the share of renewable energy sources in the primary energy balance of Latvia was 34.2%. Wood is the most significant local fuel in Latvia. In 2004, its share in Latvia’s primary energy balance was 24.7% of the total consumption of energy resources (10).

Latvia’s future hydropower production potential

The utilisation of small hydropower production is regulated, taking into consideration the national safety and environment protection concerns. Practically the potential has been fully utilised and further benefits can be reached only through increasing the efficiency of existing plants (10).

Latvia’s future wind energy potential

Latvia has also gained positive experience in using wind for power generation – the largest wind farm in central and eastern Europe is operating in Latvia. However, wind share of total electricity consumption in Latvia was only 0.8% by the end of 2010. Overall in the EU, in a normal wind year, installed wind capacity at the end of 2010 meets 5.3% of the EU’s electricity needs (11).

Vulnerabilities Europe


The current key renewable energy sources in Europe are hydropower (19.8% of electricity generated) and wind. By the 2070s, hydropower potential for the whole of Europe is expected to decline by 6%, translated into a 20 to 50% decrease around the Mediterranean, a 15 to 30% increase in northern and eastern Europe and a stable hydropower pattern for western and central Europe (1,3,4). In areas with increased precipitation and runoff, dam safety may become a problem due to more frequent and intensive flooding events (5).

It has become apparent during recent heat waves and drought periods that electricity generation in thermal power plants may be affected by increases in water temperature and water scarcity. In the case of higher water temperatures the discharge of warm cooling water into the river may be restricted if limit values for temperature are exceeded. Electricity production has already had to be reduced in various locations in Europe during very warm summers (e.g. 2003, 2005 and 2006) (5,8).

Extreme heat waves can pose a serious threat to uninterrupted electricity supplies, mainly because cooling air may be too warm and cooling water may be both scarce and too warm (9).

Climate change will impact thermoelectric power production in Europe through a combination of increased water temperatures and reduced river flow, especially during summer. In particular, thermoelectric power plants in southern and south-eastern Europe will be affected by climate change. Using a physically based hydrological and water temperature modelling framework in combination with an electricity production model, a summer average decrease in capacity of power plants of 6.3–19% in Europe was shown for 2031–2060 compared with 1971-2000, depending on cooling system type and climate scenario (SRES B1 and A2) (12).

Overall, a decrease in low flows (10th percentile of daily distribution) for Europe (except Scandinavia) is projected with an average decrease of 13-15% for 2031–2060 and 16-23% for 2071-2100,compared with 1971-2000. Increases in mean summer (21 June - 20 September) water temperatures are projected of 0.8-1.0°C for 2031–2060 and 1.4-2.3°C for 2071-2100, compared with 1971-2000. Projected water temperature increases are highest in the south-western and south-eastern parts of Europe (12).

By the 22nd century, land area devoted to biofuels may increase by a factor of two to three in all parts of Europe (2).


It may become more challenging to meet energy demands during peak times due to more frequent heat waves and drought conditions (1). Strong distributional patterns are expected across Europe — with rising cooling (electricity) demand in summer in southern Europe, compared with reduced heating (energy) demand in winter in northern Europe (7).
