Energy and electricity supply have become vital for nearly every European nation over the past year, as the region shifts away from its dependence on Russian fuel imports. While many countries have been making progress in their energy transition away from fossil fuels, nearly half of European countries are still dependent on them as their primary source of electricity generation. This graphic maps out European countries by their top source of electricity generation using data from Electricity Maps and the IEA, along with a breakdown of the EU’s overall electricity generation by source in 2021.
Europe’s Electricity Generation by Energy Source
Europe has been steadily transitioning towards renewable sources of energy for their electricity generation, making considerable progress over the last decade. In 2011, fossil fuels (oil, natural gas, and coal) made up 49% of the EU’s electricity production while renewable energy sources only made up 18%. A decade later, renewable energy sources are coming close to equaling fossil fuels, with renewables making up 32% of the EU’s electricity generation compared to fossil fuels’ 36% in 2021. The expansion of wind and solar generation have been the primary drivers in this shift towards renewables, going from only generating 8% of the EU’s electricity in 2011 all the way to 19% in 2021. While this might still seem small, the EU’s share of wind and solar electricity generation is tied for first alongside Oceania when compared to other regions around the world. While hydropower doesn’t make up as big of a share as other sources, it’s the most common primary source of electricity generation in Europe, playing an important role in providing renewable energy. Nuclear energy is the largest single source of electricity generation in the EU and across Europe despite its decline over the past couple of decades. Back in 2001, nuclear energy made up one-third (33%) of the EU’s electricity generation, and in the following 20 years fell down to 25%.
The Primary Electricity Sources of Europe’s Major Nations
When looking at individual nations, the majority of Europe’s largest countries have fossil fuels as their largest primary single source of electricity.
Germany remains heavily reliant on coal power, which from 2017 to 2021 generated 31% of the nation’s electricity. Despite the dependence on the carbon intensive fossil fuel, wind and solar energy generation together made up more of Germany’s electricity generation at 33% (23% for wind and 10% for solar).
France is Europe’s largest economy that primarily relies on nuclear power, with nuclear power making up more than half of the country’s electricity production.
Italy, the UK, and the Netherlands are all primarily natural gas powered when it comes to their electricity generation from 2017 to 2021. While Italy is the most reliant of the three at 42% of electricity generated by natural gas, the Netherlands (40%), and the UK (38%) aren’t too far off.
Spain is an outlier among major European nations and a success story in a transition towards renewable energy sources. While in the period from 2017-2021 the country was primarily dependent on natural gas (29%), in 2022 natural gas’ contribution to electricity generation fell to 14% as wind rose up to become the primary electricity generator with a 32% share.
Accelerating the EU’s Energy Transition
Since Russia’s invasion of Ukraine, energy independence in the EU has become of utmost importance, and countries have taken the opportunity to accelerate their transition towards renewable energy sources. A new report from Ember highlights how the transition made considerable progress in 2022, with solar and wind power (22%) overtaking natural gas (20%) in electricity generation for the first time ever. While 2022 did see an increase in fossil fuel electricity generation for the EU, Ember is expecting it to decline in 2023 by as much as 20%. If the EU can sustain this accelerated shift away from fossil fuels, this map of primary energy sources of electricity generation could feature many more renewable and low-carbon energy sources in the near future. on
#1: High Reliability
Nuclear power plants run 24/7 and are the most reliable source of sustainable energy. Nuclear electricity generation remains steady around the clock throughout the day, week, and year. Meanwhile, daily solar generation peaks in the afternoon when electricity demand is usually lower, and wind generation depends on wind speeds.As the use of variable solar and wind power increases globally, nuclear offers a stable and reliable backbone for a clean electricity grid.
#2: Clean Electricity
Nuclear reactors use fission to generate electricity without any greenhouse gas (GHG) emissions.Consequently, nuclear power is the cleanest energy source on a lifecycle basis, measured in CO2-equivalent emissions per gigawatt-hour (GWh) of electricity produced by a power plant over its lifetime. The lifecycle emissions from a typical nuclear power plant are 273 times lower than coal and 163 times lower than natural gas. Furthermore, nuclear is relatively less resource-intensive, allowing for lower supply chain emissions than wind and solar plants.
#3: Stable Affordability
Although nuclear plants can be expensive to build, they are cost-competitive in the long run. Most nuclear plants have an initial lifetime of around 40 years, after which they can continue operating with approved lifetime extensions. Nuclear plants with lifetime extensions are the cheapest sources of electricity in the United States, and 88 of the country’s 92 reactors have received approvals for 20-year extensions. Additionally, according to the World Nuclear Association, nuclear plants are relatively less susceptible to fuel price volatility than natural gas plants, allowing for stable costs of electricity generation.
#4: Energy Efficiency
Nuclear’s high energy return on investment (EROI) exemplifies its exceptional efficiency. EROI measures how many units of energy are returned for every unit invested in building and running a power plant, over its lifetime. According to a 2018 study by Weissbach et al., nuclear’s EROI is 75 units, making it the most efficient energy source by some distance, with hydropower ranking second at 35 units.
#5: Sustainable Innovation
New, advanced reactor designs are bypassing many of the difficulties faced by traditional nuclear plants, making nuclear power more accessible.
Small Modular Reactors (SMRs) are much smaller than conventional reactors and are modular—meaning that their components can be transported and assembled in different locations. Microreactors are smaller than SMRs and are designed to provide electricity in remote and small market areas. They can also serve as backup power sources during emergencies.
These reactor designs offer several advantages, including lower initial capital costs, portability, and increased scalability.
A Nuclear-Powered Future
Nuclear power is making a remarkable comeback as countries work to achieve climate goals and ultimately, a state of energy utopia. Besides the 423 reactors in operation worldwide, another 56 reactors are under construction, and at least 69 more are planned for construction. Some nations, like Japan, have also reversed their attitudes toward nuclear power, embracing it as a clean and reliable energy source for the future.
