What Is Green Electricity? Guide to Renewable Energy in Sweden 2026
Interest in green electricity has increased significantly in Sweden over the past few years. For many households, choosing an electricity agreement is no longer only about price and contract length. More consumers also want to understand how the electricity is produced and what impact it has on the environment and climate.
At the same time, the term “green electricity” often creates confusion. Many people wonder whether the electricity in their home actually becomes different, what guarantees of origin mean, and whether choosing a renewable electricity agreement truly makes any difference.
The short answer is that green electricity mainly concerns how the electricity is produced and which type of energy production your agreement supports over time.
In this guide, we explain how green electricity works, the different types of renewable energy available, and what to consider when comparing electricity agreements.

What Does Green Electricity Actually Mean?
When people talk about green electricity, they usually mean electricity produced from renewable energy sources rather than fossil fuels such as coal, oil, or natural gas.
This primarily includes energy generated from:
- hydropower
- wind power
- solar power
- bioenergy
What these energy sources have in common is that they are naturally renewable and generally have a lower climate impact than fossil based electricity production.
At the same time, it is important to understand that all electricity transported through the grid is physically mixed together. This means it is impossible to separate “green electricity” from other electricity once it reaches your wall outlet.
What determines whether your agreement is considered green is instead how the electricity was produced and which guarantees of origin are connected to the agreement.
How Do Guarantees of Origin Work?
Guarantees of origin form the foundation of how the green electricity market works in Sweden and across Europe.
When renewable electricity is produced, for example from wind or hydropower, a guarantee of origin is issued for the corresponding amount of electricity generated. This guarantee functions as a certificate proving that the electricity comes from a renewable energy source.
When you sign an agreement for green electricity, the electricity provider purchases guarantees of origin matching your electricity consumption. This allows the provider to guarantee that the same amount of renewable electricity has been produced somewhere within the electricity system.
This does not mean the exact electricity reaching your home comes directly from a specific wind turbine or hydropower plant. Instead, the system creates demand for renewable energy production over time.
For many consumers, this long term market signal is one of the most important aspects of choosing green electricity.
What Types of Renewable Electricity Exist?
Sweden has relatively strong access to renewable energy compared with many other European countries. At the same time, the various energy sources function differently and each has its own strengths.
Hydropower
Hydropower is Sweden’s largest renewable energy source and has long been a central part of the Swedish electricity system.
One of the biggest advantages of hydropower is that production is stable and adjustable. Water reservoirs can be used to regulate electricity generation depending on demand, making hydropower important for maintaining grid stability.
At the same time, hydropower also affects natural environments and waterways, which means environmental discussions around expansion still continue.
Wind Power
Wind power has expanded rapidly in Sweden over recent years and now accounts for a growing share of electricity production.
When wind conditions are strong, wind power can produce large amounts of relatively inexpensive electricity with low climate impact. The challenge is that production depends heavily on weather conditions.
This means wind power often needs to be combined with other energy sources capable of stabilizing the electricity system during periods with little wind.
Solar Power
Solar power still represents a smaller share of Sweden’s total electricity production, but growth has accelerated rapidly among both private households and larger energy companies.
Production is highest during summer when sunlight is strongest and electricity consumption is often lower. Because of this, solar power complements other energy sources relatively well within the Swedish energy system.
Interest in private solar panel installations has also increased significantly as electricity prices and awareness around energy efficiency continue rising.
Bioenergy
Bioenergy is produced from biological materials such as:
- forestry residues
- waste products
- pellets
- other organic materials
Sweden uses relatively large amounts of biofuels compared with many other countries, and bioenergy plays an important role in both heating and electricity production.
What Is Bra Miljöval?
Not all green electricity agreements are identical, and this is where certifications such as Bra Miljöval become important.
Bra Miljöval is an environmental certification created by the Swedish Society for Nature Conservation and is considered one of the most comprehensive electricity labels in Sweden.
To receive the Bra Miljöval certification, it is not enough for the electricity to simply be renewable. The agreement must also meet requirements related to:
- environmental responsibility in production
- energy efficiency measures
- investments in environmental projects
- protection of biodiversity and natural habitats
Because of this, agreements with Bra Miljöval may sometimes cost slightly more than standard renewable agreements, but many consumers choose them because the certification places stricter environmental requirements on the entire production process.
For households wanting to make the most environmentally focused choice possible, this is often considered the strongest sustainability label available on the Swedish market.
Does Choosing Green Electricity Actually Make a Difference?
This is one of the most common questions regarding green electricity, and the answer is more nuanced than many people expect.
Physically, all households receive electricity from the same connected power grid. It is therefore impossible to direct a specific type of electricity to a particular household.
At the same time, demand for renewable electricity influences the market over the long term.
When more households choose renewable agreements:
- demand for guarantees of origin increases
- investments in renewable production become more attractive
- energy companies gain stronger incentives to expand renewable generation
For agreements such as Bra Miljöval, there are often additional environmental requirements and investments connected to the agreement itself.
This means the choice of electricity agreement can still contribute to the long term development of the energy market.
Is Green Electricity More Expensive?
In the past, green electricity agreements were often noticeably more expensive than standard agreements. Today, however, the price differences are usually much smaller.
In many cases, the difference is only a small monthly amount, and some providers offer renewable electricity with little or no additional cost.
At the same time, prices vary between providers and agreement types, which is why it is important to compare:
- total costs
- monthly fees
- markups
- contract length
- overall conditions
It is therefore wise not to choose an agreement solely based on “green electricity” marketing, but also to review how the agreement is actually structured.
What Should You Consider When Choosing Green Electricity?
For many households, the goal is finding a balance between:
- price
- sustainability
- stability
- contract terms
The most important thing is therefore understanding what the agreement actually includes and how the provider works with guarantees of origin and environmental certifications.
It can also be useful to consider:
- whether you prefer fixed or variable pricing
- how much electricity your household consumes
- whether you prioritize the lowest possible cost or stronger environmental requirements

Green Electricity and the Future Energy Market
As electrification continues increasing across Sweden, questions around energy production are becoming increasingly important. Electricity is now used for far more than before, including:
- electric vehicles
- industrial production
- heating
- charging infrastructure
At the same time, expectations for sustainable and fossil free energy production continue growing.
For many consumers, choosing green electricity is therefore not only about today’s electricity bill but also about supporting the type of energy system they want to see in the future.
Common Questions About Green Electricity
Is green electricity really environmentally friendly?
Green electricity generally has a significantly lower climate impact than fossil based electricity production, especially when generated from hydropower, wind power, or solar energy. At the same time, all energy production affects the environment in different ways.
Do I receive different electricity in my home if I choose green electricity?
No. All electricity is mixed together in the same electricity grid. The difference lies in which type of production your agreement supports through guarantees of origin.
Is Bra Miljöval better than standard green electricity?
Bra Miljöval includes stricter environmental requirements than many standard renewable agreements and also includes environmental investments and nature conservation measures.
Is green electricity more expensive?
In many cases, the price difference is relatively small today. Agreements with advanced environmental certifications may however cost slightly more.
Can green electricity be combined with fixed or variable pricing?
Yes. Green electricity can be combined with both fixed and variable agreements depending on the provider and contract type.
