You have several options to make your electricity greener – and cheaper. This applies whether you pay a fixed or variable price for your electricity. Even though the power in your socket comes from the shared grid, you can actually support the transition to renewable energy by following the five tips on this page.

Use electricity when it’s greenest

You can reduce your carbon footprint by using electricity when there’s a high share of renewable energy in the grid – typically when the sun is shining or the wind is blowing. It’s usually a good idea to avoid using power during peak hours, such as weekdays between 3 PM and 8 PM.

How to do it:

  • Plan ahead: Use your electricity provider’s app – or a free app like Watts – to monitor electricity prices and the expected share of green energy for the upcoming day. Some apps offer forecasts several days ahead.

  • Check past usage: Log in with MitID on Eloverblik to see how green your electricity has been and which energy sources it came from.

By combining these two tools, you get a clear overview of your electricity, making it easy to choose the greenest and cheapest times to start your washing machine or charge your electric car.

Choose a green electricity provider

Your choice of electricity provider matters more than you might think. In Denmark, there are several providers that purchase 100% green electricity from renewable sources such as wind, solar, and hydropower. Even though this doesn’t mean that the electricity in your socket is exclusively green – since we are all connected to the shared electricity grid – your choice still makes a difference.

Many providers offer guarantees of origin, which document that the electricity you pay for comes from green sources. In addition, several electricity providers invest in new renewable and sustainable energy projects.

By choosing a green electricity provider, you are supporting the green transition because your payment directly contributes to investments in renewable and sustainable energy.

Switching electricity providers is easy. Simply search online for the provider you want and sign up via their website.

Save electricity

Is it hard to change habits? Is it easy to get confused by all the green advice? Does it even make a difference how you act?
The answer is yes, yes and definitely yes!

When you use less energy – less energy needs to be produced. Simple as that.

On SparEnergi’s Electricity Pyramid, you can quickly get an overview of which devices in your home consume the most electricity. At the bottom of the pyramid, you’ll find the devices that require the most energy.

But if you should take away just one thing – make it this:

The greenest and cheapest energy… is the energy you don’t use.

Become a co-owner of a wind farm

Lillebælt Syd is a future offshore wind farm located between Als and Funen, expected to be operational by 2029. With 11 wind turbines and a capacity of 165 MW of green electricity, the park will be able to cover the electricity consumption of 148,000 households and significantly contribute to Sønderborg’s goal of achieving CO₂-neutral energy by 2029.

In 2027, at least 20 % of the project will be offered as ownership shares to local citizens who wish to become co-owners. You can already read about the Right to Purchase Scheme and the Loss of Value Scheme, which describe the opportunity to invest and the compensation rules if your property value is affected by proximity to the turbines.

If you are interested in becoming a co-owner or have questions about the project, you can find more information on the Lillebælt Syd website or contact SONFOR at vind@sonfor.dk.

Generate your own electricity with solar panels

Installing solar panels on your roof can be a very good idea for several reasons. They produce green energy for your home and feed surplus electricity into the shared grid when you don’t use it yourself. Additionally, rooftop solar panels don’t take up space in the landscape.

During 2025, a new solar panel grant scheme will open, targeting apartment buildings. Public housing associations, private rental properties, and apartment buildings with owner-occupied or cooperative apartments can apply for financial support to cover part of the costs for purchasing and installing solar panel systems. Read more about the solar panel grant scheme.

As a private homeowner, you cannot apply for support from this scheme. However, you can take advantage of the new home improvement tax deduction for the installation and connection of solar panels.
