Electricity, electric lamps, renewable energies..., although all this now seems taken for granted, it has not always been so. Humanity has lived most of its time without these technological feats that have profoundly shaped our world and made it as comfortable as we know it.
Today, it seems completely normal to come home after a long day at work, to press a switch to light up your bedroom. However, this would not have been possible without the creative spirit and genius of numerous scientists that can be described as founding fathers of energy.
At SirEnergies, we invite you to discover the great inventors who made it possible to revolutionize the world of energy.
Nikola Tesla, the genius of alternating current
Do you know the company Tesla? It is so named to honor this exceptional character who left an indelible mark on him. The field of energy.
Her short story
Nikola Tesla was an electrical and mechanical engineer of Serbian origin. Born on July 10, 1856 and died on January 7, 1943, he is with his 900 patents, including 111 American ones, one of the most prolific inventors of the story. This precocious genius was able to perform complex mathematical calculations from an early age.
When he was still at École Polytechnique in 1875, he studied Gramme's dynamo, which allowed him to imagine advantages of alternating current. He would later be one of Thomas Edison's fiercest rivals, who swore by direct current. With his genius, he could have been financially successful like some of his contemporaries at the time had he not been such a poor businessman.
The genius with multiple inventions
Nikola Tesla is undoubtedly one of the most renowned inventors in history and an outstanding innovator in the world of energy. One of his greatest discoveries and his most influential work was the invention of alternating current. It is used nowadays to operate various household appliances such as dryers and washers.
One of his patents also concerns a rotating electromagnetic field thanks to which an alternating current made it possible to power a motor without having been converted to direct current upstream. It is this process that allowed the creation of generators and AC transformers.
Fiercely opposed to Edison on the superiority of alternating current over direct current, he nevertheless succeeded in demonstrating it with his friend Westinghouse. Since then, its high efficiency, especially in terms of energy and economy, is no longer in doubt.
During this same period, the brilliant inventor developed A hydroelectric system which made it possible to convert the energy of Niagara Falls into electricity. It was used to feed industries in the city of Buffalo. He even fought for several decades with Edison for several patents.
Nikola Tesla also developed a polyphase system which made it possible to transmit electricity over long distances. He also developed the first radio transmitter capable of sending electromagnetic energy from one point to another without using cables. However, all this is far from being the only invention of the Serbian genius. Nikola Tesla also distinguished himself with the invention of high-frequency generators, the Tesla coil, rotating field theory, and neon signs.
Thomas Edison, the king of direct current
Thomas Alva Edison was one of the emblematic figures in the field of energy in the 19th centuryE And in the XXE century. Born in 1847 in Milan in the United States, he distinguished himself at an early age as a hyperactive child with insatiable curiosity. Forced to drop out of school after only a few months, his education was provided by his mother.
Self-taught at heart and with a futuristic vision, he soon became the prolific inventor as we know him today. At the time of his death, he had more than a thousand patents covering fields as varied as cinema, telegraph or electric rail transport.
The incandescent light bulb
Thomas Edison was actively looking for a way to produce light from electricity. He had his revelation during one of his trips to Sierra Madre in Wyoming. The idea then came to him to introduce a filament heated by an electric current into a bulb in order to produce light.
However, to find the ideal filament capable of accomplishing this feat, he made nearly 1,200 attempts and then filed a patent application for the carbonized bamboo filament. However, it only lasts 30 hours. It was then another inventor by the name of Latimer who addressed this problem by proposing the carbon filament. However, the first form of electric light is Attributed to Humphry Davy in 1802.
However, it is thanks to Thomas Edison's research that many cities in the Old Continent and the United States have benefited from DC electric lighting systems. In terms of mass-produced commercial light forms, the Edison bulb is undoubtedly a leader. Years later, the direct current system so dear to Edison was finally replaced by the alternating current developed by Tesla, one of his former employees.
The power plant
In the field of energy, Thomas Edison did not only shine with the incandescent light bulb. The Edison Electric Light Company of American engineers in fact founded the very first electric power plant in the world based on six dynamos on September 4, 1882. The purpose of this power plant was to produce direct current in the Wall Street district of Manhattan. The energy produced could power 1,200 lamps that will be used to light 85 homes and offices.
A pioneer in renewable energies
Thomas Edison was a pioneer of renewables. He has in fact conducted multiple experiments with wind turbines at home for the production of electricity in order to provide an independent source of energy. He also teamed up with his friend Henry Ford in order to Develop an electric car that works with rechargeable batteries. He saw electric cars as cleaner alternatives.
Alessandro Volta, the inventor of the battery
This time we are going to Italy to better understand the origin of the name given to the unit of electromotive force, it is the volt. This unit has been Donated by the Congress of Electricians in honor of Alessandro Giuseppe Antonio Anastasio Volta, an Italian physicist.
Born on February 18, 1745 in Como, a city not far from Milan in the Italian Alps, he is far from the archetype of early genius as we knew him. In fact, he only started speaking at the age of four. However, being included in this list of inventors, this did not stop him from becoming a luminary in his field.
Later, He taught physics at school royal of his city, but also carried out research on electricity in parallel. Very curious, he was at the origin of numerous discoveries, including that of methane.
The invention of the voltaic battery
Volta has always been passionate about the study of electrical phenomena. In fact, it was he who perfected The electrophore, a machine that allows you to generate static electricity. Thanks to this machine, he discovered numerous laws that explain the functioning of the capacitor. However, his greatest invention is undoubtedly that of the voltaic battery.
Curious by nature, Volta had a click when he read a publication by the professor of biology and physiology Luigi Galvani. This was about his observations on a dead frog that had its spinal nerve attached to a copper wire. When it and its legs touched an iron disc, a contraction was observed. It was Volta who proposed the most plausible explanation for this phenomenon: theElectricity is produced by contact between copper and iron and not by living matter as Luigi thought.
Volta also understood one thing by observing the electricity released by torpedo rays, on the back made up of repeated patterns: it is possible to produce electricity by stacking pairs of zinc-copper disks separated by a cloth dipped in a salt water solution. He then developed a tension table.
His research then led to the creation of the first electric battery in 1800. This cell was the first continuous source of electricity and is the precursor to dry batteries commonly used today. This invention allowed him to be knighted in 1810 by Napoleon I.Er and to obtain the title of Count of the Kingdom.
Joseph Swan, another pioneer of the electric lamp
While Edison was famous for his contribution to the advent of electrical lighting systems, he is not the only one. Across the Atlantic in Europe, more precisely in England, another genius is also rightly considered to be one of the pioneers of these systems. It's Joseph Swan.
Zoom on the character
Sir Joseph Wilson Swan was an English physicist and chemist born on October 31, 1828 and died on May 27, 1914 in Warlingham. In particular, it is known as theInventor of the photographic plate dryer that allowed a significant improvement in photography and in the development of modern photographic films. From an apprentice to a pharmacist to an assistant in a chemical manufacturing company, he soon developed a functional electric lamp.
Joseph Swan's electric lamp
Between the years 1850 and 1860, Joseph Swan conducted numerous experiments in order to create your own lighting system electric. However, his first tests were inconclusive because vacuum pumps of the time were unable to remove enough air from the lamps. With the design of better pumps in the mid-1870s, Swan resumed his experiments and demonstrated his functional lamp at the Newcastle Chemical Society in 1879.
However, in his lamp, he used a carbon rod with low thermal resistance. As a result, the conductors responsible for bringing electricity back to the lamp had to be rather short or very thick. While the use of such a lamp was not prohibitive in the context of an experiment, it was for real use.
Looking for the best filament for his lamp, just like Edison, Swan ended up develop a patented process which allowed nitrocellulose to be pressed through holes to form fibers.
As you can see, the world of energy has been marked by great discoveries and inventions that have profoundly changed our lifestyles: alternating current, direct current, invention of the electric battery... This was possible with the genius of scientists like Thomas Edison, Nikola Tesla, Alessandro Volta, Alexander Graham Bell, Joseph Swan...

What is the main objective of the Multiannual Energy 3 Programming?
.png){kind=icon}
The central objective of PPE 3 is to engage France towards carbon neutrality by 2050 by breaking the country's historical dependence on fossil fuels.
Today, approximately 60% of final energy consumption in France still relies on imported oil and natural gas. PPE 3 aims to radically reverse this trend by setting an ambitious target: to reach 60% of carbon-free energies in final consumption by 2030.
To achieve this, PPE 3 pursues three major sub-objectives:
- Massive decarbonization: Replace fossil fuels with low-carbon electricity or renewable heat in industry, transport and buildings.
- Energy sovereignty: Reduce the national energy bill (around 60 billion euros per year) and get rid of the volatility of the global gas and oil markets.
- Economic competitiveness: Guarantee businesses and households access to stable, abundant and predictable energy at a predictable cost, disconnected from geopolitical crises.
Pourquoi le mécanisme de capacité a-t-il été créé ?
Instauré en 2017, ce dispositif répond à un enjeu de sécurité nationale.
L'électricité ne se stockant pas à grande échelle, le réseau doit être capable de répondre instantanément à la demande, même lors des pics de froid hivernaux. Le mécanisme incite financièrement les producteurs à maintenir leurs centrales disponibles et les entreprises à réduire leur consommation (effacement) lors de ces périodes critiques.
Qu'est-ce que le dispositif VNU qui remplace l'ARENH en 2026 ?
La Vente de Nucléaire Universelle (VNU) est le nouveau mécanisme de régulation des prix de l'électricité en France. Contrairement à l'ARENH, il ne s'agit plus d'un volume fixe à prix réduit, mais d'une redistribution financière des revenus excédentaires d'EDF aux consommateurs, basée sur les prix de marché et les coûts de production du nucléaire historique.
What is the Multiannual Energy Programming (PPE)?
La Multiannual Energy Programming (PPE) is the strategic management tool for France's energy policy. Established by the 2015 law on energy transition for green growth (LTECV), it serves as a compass for the State, communities and businesses.
Concretely, the PPE sets the priorities for action of the public authorities for the management of all forms of energy on the national territory. It covers a period of ten years, divided into two periods of five years, and must be revised periodically to adapt to technological and economic developments.
It deals with major topics such as:
- Security of supply.
- Improving energy efficiency and reducing consumption.
- The development of renewable and recovered energies.
- The electrical production strategy (nuclear, thermal, etc.).
- The balanced development of networks and storage.
It is crucial not to confuse it with National Low Carbon Strategy (SNBC). While SNBC sets carbon budgets (the ceilings for greenhouse gas emissions by sector), the PPE determines the technical and energy resources to achieve them.
Pourquoi le seuil de 78 €/MWh est-il critiqué par les experts ?
Ce seuil est jugé élevé par rapport aux prévisions actuelles du marché. Si le prix de l'électricité reste en dessous de 78 €/MWh, les entreprises ne bénéficieront d'aucune redistribution. Cela signifie que la protection promise par la réforme pourrait être inexistante dans un marché baissier, d'où l'importance de stratégies de sourcing agiles et d'outils de monitoring comme Pilott.
Fin de l'ARENH au 31 décembre 2025 : comment sécuriser mon budget énergie pour 2026?
La fin de l'ARENH (Accès Régulé à l'Électricité Nucléaire Historique) marque l'arrêt de la fourniture d'électricité à prix fixe garanti (42 €/MWh).
Dès le 1er janvier 2026, les entreprises sont exposées aux prix de marché, mais deux nouveaux mécanismes de régulation prennent le relais, bien que leur logique soit différente :
- Le Versement Nucléaire Universel (VNU) : Ce n'est pas un tarif d'achat, mais un mécanisme de redistribution a posteriori. Si les prix de marché de l'électricité nucléaire dépassent un certain seuil (environ 78 €/MWh selon les estimations pour 2026), EDF reversera 50 % des revenus excédentaires aux consommateurs. Attention : Si les prix de marché restent modérés (sous les 78 €/MWh), le VNU ne se déclenche pas. Il agit comme une assurance contre les flambées extrêmes, pas comme un tarif bas garanti.
- Les CAPN (Contrats d'Allocation de Production Nucléaire) : Réservés aux industriels électro-intensifs, ces contrats de long terme (10-15 ans) permettent de réserver une part de la production nucléaire en échange d'une participation aux coûts du parc. Ils offrent une visibilité sur le long terme pour 50 à 70 % des volumes consommés.
Conseil stratégique : Ne comptez pas sur le VNU pour réduire votre facture en 2026 si les marchés restent stables. Auditez vos contrats dès maintenant pour intégrer une part de prix fixe ou explorer des "Power Purchase Agreements" (PPA) pour sécuriser vos coûts sur le long terme.
Quelle est la différence entre un prix Forward et un prix Spot ?
Le prix Forward est fixé à l'avance (sécurité budgétaire), tandis que le prix Spot varie heure par heure selon le marché (opportunité mais risque élevé).
What are the electricity offers offered by bellenergie Business?
The range E @sy is available in four pricing structures to adapt to each risk profile:
- E @sy Fixed: 100% budget visibility without variation.
- E @sy Click: Smoothed price thanks to staggered purchases on the markets.
- E @sy Block + Spot: A mix between a secure base and a portion indexed to daily prices.
- E @sy Sport: A 100% dynamic offer to take advantage of downside opportunities in real time.
What are the customer reviews on bellenergie Business's customer service?
In 2025, the supplier had a NPS (Net Promoter Score) of +16 and a note of 4,17/5.
Satisfaction is based on a “zero solicitation” model and 100% in-house customer service in Toulon, guaranteeing proximity and responsiveness that cannot be found with major historical suppliers.
Pourquoi l'IA ne peut-elle pas prédire le prix de l'énergie avec exactitude ?
Car les marchés dépendent de facteurs exogènes imprévisibles (géopolitique, météo soudaine, politique) que les modèles basés sur l'historique ne peuvent pas anticiper, tout comme on ne prédit pas le Loto.
Quel sera l'impact réel du VNU sur ma facture d'électricité professionnelle ?
L'impact dépendra des prix de marché. Le mécanisme prévoit une redistribution si les prix dépassent 78 €/MWh. Cependant, si les cours restent bas (actuellement autour de 60 €/MWh), le dispositif ne s'activera pas. La facture sera alors indexée à 100% sur les prix de marché, rendant le choix du fournisseur et du moment d'achat critiques.
Mon entreprise peut-elle tirer profit des nouvelles Heures Creuses (11h-17h)?
Absolument. La réforme des heures creuses vise à absorber la surproduction solaire en milieu de journée. Les créneaux d'heures creuses se déplacent progressivement vers la plage 11h00 – 17h00, notamment en été. C'est une opportunité majeure pour les sites industriels ou tertiaires capables de flexibilité.
Conseil stratégique :
- Pilotage de la charge : Si vous avez des processus énergivores (fours, broyeurs, recharge de flotte de véhicules électriques, production de froid), déplacez leur fonctionnement sur la pause méridienne. L'électricité y sera moins chère et moins carbonée.
- Autoconsommation : C'est le moment idéal pour coupler cette tarification avec une installation photovoltaïque en toiture ou en ombrière de parking. Vous effacez votre consommation réseau au moment où le tarif serait le plus avantageux, ou vous profitez des prix bas du réseau si votre production ne suffit pas.
Quels sont les cas d'usage concrets des différents types d'IA pour un acheteur d'énergie ?
Chaque modèle d'IA répond à un besoin spécifique du cycle d'achat :
- L’IA générative sert d'assistant de recherche pour synthétiser en quelques minutes des rapports de marché massifs (veille stratégique).
- L’IA déterministe est l'outil de la fiabilité : elle est indispensable pour le forecast (prévision de consommation) car ses calculs sont mathématiques et reproductibles.
- L’IA probabiliste est dédiée à la gestion des risques : elle simule des scénarios (ex: météo, stocks) pour quantifier l'incertitude sur les budgets futurs.
L'expertise humaine reste néanmoins indispensable.
L'IA remplace-t-elle les analystes en énergie ?
Non. L'IA traite la donnée (data processing), mais l'analyste apporte la compréhension du contexte (market sentiment) et la prise de décision stratégique.
