Africa-Press – Senegal. <\/strong><\/span>Une reque\u0302te a\u0300 Gemini, l\u2019intelligence artificielle (IA) de Google, consomme moins d\u2019e\u0301nergie que de regarder neuf secondes de te\u0301le\u0301vision, affirme jeudi le ge\u0301ant ame\u0301ricain de la tech qui cite une e\u0301tude mene\u0301e par ses chercheurs alors que la voracite\u0301 e\u0301nerge\u0301tique de l\u2019IA reste un proble\u0300me majeur du secteur.<\/p>\n

En moyenne, une reque\u0302te (appele\u0301e \u00ab prompt \u00bb) textuelle dans les applications Gemini consomme 0,24 wattheure (Wh) d\u2019e\u0301nergie, soit moins que le visionnage de neuf secondes de te\u0301le\u0301vision moderne qui correspond a\u0300 environ 100 Wh, estiment les chercheurs de Google.<\/p>\n

Une reque\u0302te e\u0301met par ailleurs 0,03 gramme d\u2019e\u0301quivalent dioxyde de carbone et consomme 0,26 millilitre d\u2019eau, l\u2019e\u0301quivalent d\u2019environ cinq gouttes, ajoutent-ils. Cette e\u0301tude porte sur des donne\u0301es de mai 2025 collecte\u0301es a\u0300 travers les diffe\u0301rentes applications ou\u0300 Gemini est pre\u0301sent.<\/p>\n

Google ne de\u0301taille pas ce qu\u2019il entend par \u00ab prompt \u00bb, s\u2019il s\u2019agit d\u2019un mot ou d\u2019une suite de mots, et refuse de communiquer le nombre de reque\u0302tes formule\u0301es sur Gemini chaque jour, ce qui permettrait d\u2019avoir une ide\u0301e de la consommation d\u2019e\u0301nergie globale du mode\u0300le.<\/p>\n

Google voit d\u2019ailleurs ses e\u0301missions de gaz a\u0300 effet de serre augmenter.<\/p>\n

Elles ont atteint 15,2 millions de tonnes de CO2 en 2024, soit plus de 50% de plus qu\u2019en 2019, son anne\u0301e de re\u0301fe\u0301rence, d\u2019apre\u0300s son dernier rapport environnemental annuel, et ce, en grande partie a\u0300 cause de ses centres de donne\u0301es, indispensables au de\u0301veloppement de l\u2019IA.<\/p>\n

Pour son e\u0301tude, le groupe a comptabilise\u0301 les phases de calcul actif des mode\u0300les d\u2019IA pour ge\u0301ne\u0301rer des re\u0301ponses aux reque\u0302tes des utilisateurs, l\u2019e\u0301nergie re\u0301elle consomme\u0301e par les puces et celle des processeurs et des centres de donne\u0301es dans leur ensemble.<\/p>\n

Google explique ainsi avoir pris en compte l\u2019e\u0301nergie des machines inactives, qui doivent e\u0302tre alimente\u0301es en permanence pour e\u0302tre pre\u0302tes a\u0300 ge\u0301rer a\u0300 tout moment des pics de trafic, les syste\u0300mes de refroidissement des serveurs tre\u0300s e\u0301nergivores et d\u2019autres charges indirectes de ses centres de donne\u0301es.<\/p>\n

Ces chiffres n\u2019inte\u0300grent cependant pas tout l\u2019entrai\u0302nement des mode\u0300les d\u2019IA, et sont a\u0300 prendre avec pre\u0301caution, l\u2019e\u0301tude n\u2019ayant pas e\u0301te\u0301 ve\u0301rifie\u0301e par un tiers inde\u0301pendant, comme le rappelle Google lui-me\u0302me dans une note accompagnant l\u2019e\u0301tude.<\/p>\n

Calculer l\u2019empreinte environnementale d\u2019un mode\u0300le d\u2019IA est une ta\u0302che extre\u0302mement complexe car il n\u2019existe aucune norme mondiale de mesure.<\/p>\n

Les ge\u0301ants de la tech entretiennent pour la plupart une opacite\u0301 sur le fonctionnement de ces programmes et leurs conditions de fabrication, ce qui complique la ta\u0302che des chercheurs inde\u0301pendants et des institutions internationales qui manquent de donne\u0301es.<\/p>\n

Le patron d\u2019OpenAI, Sam Altman, a par exemple re\u0301ve\u0301le\u0301 en juin que chaque reque\u0302te envoye\u0301e a\u0300 ChatGPT consommait en moyenne 0,34 Wh d\u2019e\u0301lectricite\u0301, soit l\u2019e\u0301nergie ne\u0301cessaire pour faire fonctionner un four pendant une seconde, et 0,3 ml d\u2019eau.<\/p>\n

Le dirigeant n\u2019a cependant fourni aucune explication sur la manie\u0300re dont OpenAI e\u0301tait parvenu a\u0300 ces chiffres, ce qui rend toute comparaison impossible.<\/p>\n

La question de la consommation e\u0301nerge\u0301tique de l\u2019IA est pourtant cruciale.<\/p>\n

Les centres de donne\u0301es, socle de cette technologie, devraient peser environ 3% des besoins mondiaux en e\u0301lectricite\u0301 d\u2019ici 2030, soit le double de la proportion actuelle, selon l\u2019Agence internationale de l\u2019e\u0301nergie (AIE).<\/p>\n
