The cheapest green energy offers in France
A green contract does not have to cost more. The ranking below is pulled live from our comparison engine with the Green filter applied, so it always shows the cheapest renewable offers available right now rather than a fixed snapshot. Switch to the Gas tab to see green gas options where available.

Because the extra cost of Guarantees of Origin is small, several of these green offers undercut EDF's regulated tariff for the exact same electricity, delivered through the same grid. Green and cheap are no longer mutually exclusive.
Not all "green" offers are equal
While most suppliers now claim to offer renewable electricity, the impact behind those claims varies a lot. There are two main types of green contract, told apart by how their Guarantees of Origin are sourced, and knowing the difference helps you pick one that genuinely supports the energy transition. Our French guides on green electricity offers and the VertVolt label go deeper into each.
Standard green offers
These rely on Guarantees of Origin (GO) to certify that your consumption is matched by renewable production somewhere in Europe. The electricity itself may come from non-renewable sources, and the GO is often bought separately, sometimes from older or foreign installations. They support green energy symbolically, but not always in a concrete or local way.
Premium green offers (VertVolt)
Certified by the French agency ADEME, these guarantee that both the electricity and its Guarantee of Origin are bought together from French renewable producers. Offers marked "Très engagé" go further still, sourcing energy from new, local and citizen-backed installations for maximum transparency and impact.
What actually is green electricity?
Green electricity, also called renewable electricity, is power generated from natural, sustainable sources such as wind, solar, hydro or biomass. Unlike fossil fuels, these sources produce little to no greenhouse gas emissions. When you sign a green contract in France, your supplier guarantees that for every kilowatt-hour you consume, the same amount of renewable electricity is produced and injected into the grid, proven through Guarantees of Origin.
What makes an energy "green"?
An energy source is considered green when, unlike fossil fuels, it does not exhaust the planet's natural resources, does not harm the environment, and poses no public health hazard. Its production is also intermittent, since it depends on external factors such as sunshine for solar, wind for wind power, or rainfall for hydro.
Why choose a green offer?
Even though the electricity reaching your home is physically identical, choosing a green contract still plays a real role in the energy transition. Because all electricity feeds into the same national grid, your choice increases the overall share of renewables in the mix. Over time, this supports cleaner power production in France and reduces the country's dependence on fossil fuels. Green energy is cleaner than fossil fuels, draws on inexhaustible sources, creates no radioactive waste, and, once the infrastructure is paid off, becomes highly competitive on price, which is why many green offers already sit below EDF's regulated rates.
Is there green gas in France?
Green gas exists in France, but it is less common and less developed than green electricity, so it is often slightly more expensive. Known as biomethane, it is produced locally from organic waste, such as agricultural or food waste, and injected into the same network as fossil natural gas. The market is still growing, which keeps availability limited, but you can still find cheaper green gas offers by comparing.
Not every green gas offer is 100% renewable. When a supplier sells a "green gas" contract, it usually means it injects a certain percentage of biomethane to match part of your consumption:
- a 100% green gas offer injects the full equivalent of your annual gas use as biomethane into the grid;
- a 5% green gas offer matches only 5% of your consumption with biomethane, the rest coming from traditional natural gas.
Frequently asked questions
Not necessarily. Many green offers are priced below the regulated tariff, because the cost of Guarantees of Origin is small. The ranking on this page is pulled live and lets you filter green offers by price, so you can see for yourself that several of the cheapest electricity deals on the market are also green.
No. All electricity in France, renewable or not, flows into the same national grid, so the power reaching your home is physically identical. What changes is that your supplier commits to injecting an equivalent amount of renewable electricity into the grid, which supports the energy transition.
A standard green offer relies on Guarantees of Origin that may be bought separately, sometimes from older or foreign installations. A VertVolt-certified offer (a label from the French agency ADEME) guarantees the electricity and its Guarantee of Origin are bought together from French renewable producers, with a "Très engagé" level for new and citizen-backed sites.
Yes. Green gas, or biomethane, is produced locally from organic waste and injected into the same network as natural gas. Offers range from a small share (for example 5%) up to 100% of your consumption matched with biomethane. The green gas market is still developing, so these offers are less common and sometimes a little pricier than standard gas.
