Energy production from renewable resources accounts for the vast majority of domestically produced electricity in Liechtenstein. Despite efforts to increase production, the limited space and infrastructure of the country prevents Liechtenstein from fully covering its domestic needs from renewables only. Liechtenstein has used hydroelectric power stations since the 1920s as its primary source of do. [pdf]
Energy in Liechtenstein describes energy production, consumption and import in Liechtenstein. Liechtenstein has no domestic sources of fossil fuels and relies on imports of gas and fuels. The country is also a net importer of electricity.
Samina Power Station, currently the largest of the domestic power stations, has been operational since December 1949. In 2011-2015, it underwent a reconstruction that converted it into a pumped-storage hydroelectric power station. In recent decades, renewable energy efforts in Liechtenstein have also branched out into solar energy production.
Liechtenstein has used hydroelectric power stations since the 1920s as its primary source of domestic energy production. By 2018, the country had 12 hydroelectric power stations in operation (4 conventional/pumped-storage and 8 fresh water power stations). Hydroelectric power production accounted for roughly 18 - 19% of domestic needs.
Lawena Power Station is the oldest in the country, opened in 1927. The power station underwent reconstructions in 1946 and 1987. Today, it also includes a small museum on the history of electricity production in Liechtenstein. Samina Power Station, currently the largest of the domestic power stations, has been operational since December 1949.
Liechtenstein municipalities can obtain the Energy City label if they continuously ensure efficient energy use, increase investments for renewables, including solar energy, wind energy and hydropower, and promote environmentally compatible mobility. The certificate is awarded by the Energy City Sponsoring Association.
In 2010, total consumption of electricity in the Principality of Liechtenstein amounted to roughly 350,645 MWh. In 2015, total consumption of electricity in the Principality of Liechtenstein amounted to roughly 393.6 million kWh.

As of May 2024, the average price of solar panels in Belgium is $2.48 per watt, or about €1.26 per watt peak (Wp).. As of May 2024, the average price of solar panels in Belgium is $2.48 per watt, or about €1.26 per watt peak (Wp).. The cost of solar panels has decreased in recent years, making them more accessible. Currently, a 5,000 Wp installation costs around €6,000 including VAT.. A complete solar panel installation typically costs an average of 3 000 to 5 700 euros, including installation costs and excluding VAT.. Today, the estimated selling price is around 80 euros per green certificate (consult prices in real time on the government website). [pdf]
The price of solar panels has dropped significantly in recent years. In addition, you can receive a subsidy from the government for photovoltaic panels. The average solar panel price is around €1.26 per watt peak (Wp), although the exact price depends on a number of criteria:
Installing solar panels in Belgium offers an attractive return on investment in terms of energy and cost savings. Even without green certificates, owners of photovoltaic systems can recoup their investment in just a few years. To further optimize their financial savings, here are three key ways:
For the installation of solar panels on the ground, on a protected building or in other regulated cases, you will have to contact your municipality. There are several companies active in Belgium that install solar panels.
The cost of solar panels has decreased in recent years, making them more accessible. Currently, a 5,000 Wp installation costs around €6,000 including VAT. Government subsidies for solar panel installations are gradually phasing out. In Flanders, the maximum subsidy for 2024 is €375, down from €750.
This represents around 75 solar panels of 430 Watts-peak (Wp: power under standard conditions) 32,250 Wp of installed power. 1. Income from Green Certificates : In Brussels, owners of solar panels can benefit from the green certificate system. Green certificates are granted for 10 years.
In Belgium there are two main types of solar panels. Solar Thermal Panels: these harness the sun's heat to produce hot water and heat homes. Equipped with sensors capturing up to 90% of sunlight, these panels transport heat to a water tank for storage, ensuring a continuous supply of hot water, even on overcast days.
