Gas, electricity, wood… What solution should be favored for heating in a context of exploding energy costs?

Gaz, électricité, bois... Quelle solution privilégier pour se chauffer dans un contexte d

Between January and October 2021, the prices of natural gas, almost exclusively imported from abroad, increased by almost 50%. They have not moved since, due to the implementation of the tariff shield. Without the latter, the Energy Regulation Commission (CRE) announced a few days ago that prices would have had to soar by +105.10% including tax over the entire period?! The government system has also made it possible to contain the acceleration in the price of electricity to 4% over the year 2022, when the CRE recommended an increase ten times higher at the start of the year.

Gas and electricity are exploding, and it’s not over

Yes but here it is. Even if Gabriel Attal, Minister Delegate for Public Accounts, announced last weekend that the government would still act in 2023 to limit price inflation, the tariff shield will certainly last less than the explosion in the price of these energies, between international tensions and concerns around the French nuclear fleet.

Electricity, pellets, gas, oil… How do you heat your town?

Those who thought they were getting a good deal by choosing an offer whose prices are indexed to the markets can already testify to this, with double-digit increases in recent months. For those concerned, the website of the National Energy Mediator ( offers a comparator of the different offers, in order to find the most interesting.

“It’s very easy to change supplier, all you have to do is open a contract to terminate the old one directly. But it is absolutely necessary to ensure that the offer is indexed to the regulated prices. »

With such uncertainties about gas and electricity, it may therefore be time to think about a new option for heating. “For this winter, it will be a little late because the craftsmen’s order books are full. But it’s really time to ask questions, says Anne Savignon, director of the local agency for energy and climate in Nièvre. It’s a costly investment so you have to take the time, talk to your France Rénov’ advisor to choose the best solution for your home. »

Why, at the dawn of a major energy crisis, the state of health of the French nuclear fleet is worrying

Wood remains the most interesting energy

Because not everything is possible. If you currently operate with central heating, you can replace your gas or oil boiler with a heat pump or a wood boiler. In the case of decentralized heating, the solution will be either by changing the radiators – the new ones providing greater comfort and allowing the thermostat to be lowered – or by an additional heating system via the installation of a wood-burning stove. “Despite the rise in the price of pellets and their temporary shortage, wood remains the cheapest energy, confirms Anne Savignon. In addition, the wood is most often local and sustainable because our forests are well managed. »

The photovoltaic sector continues to structure itself

Photovoltaics can also prove to be a credible option, even if the question of self-consumption still arises, production being higher in summer, and needs in winter.

But by the way, is it necessarily mandatory to change the heating system to lower your bill?? “Sometimes it’s not necessarily the first thing to do and that’s not where you have to focus your investments,” warns Florence Clément, head of consumer information at Ademe.


Insulating your home can also be a solution

And to add, “once you have reduced your heating needs by insulating your home, you can put in place the technical solutions behind adapted to the new situation”.

For Anne Savignon, the difficulties of this year 2022, which must be responded to urgently, must be an opportunity for more global reflection.

“We must work over time, on the structural side, to free ourselves from expensive energies and hydrocarbons, while trying to tend towards more sobriety, limiting its consumption and hunting down waste”, concludes the Nivernaise professional. .
