Google’s carbon emissions soar by 48% due to AI - Climate Action
www.climateaction.org

The leap in emissions is largely due to energy-guzzling data centers and supply chain emissions necessary to power artificial intelligence (AI) systems such as Google’s Gemini and OpenAI’s ChatGPT. The report estimated that in 2023, Google’s data centers alone account for up to 10% of global data center electricity consumption. Their data center electricity and water consumption both increased 17% between 2022 and 2023.

Google released 14.3 million metric tons of carbon dioxide just last year, 13% higher than the year before.

Climate scientists have shown concerns as Big Tech giants such as Google, Amazon and Microsoft continue to invest billons of dollars into AI.

    You are correct, but that coking process doesn’t have to be done with fossil fuels. Hydrogen (like you mentioned) is an alternative and you can create hydrogen using water and electricity.

    In the NL we have a pretty polluting steel mill that is currently still coal fired. They are working on a transition plan where they adapt it to be gas fired instead, with the ability down the line to make it hydrogen fired when hydrogen production capacity is up to speed.

      oh, you were talking about europe" I was thinking about america. Yeah i imagine it’s going to be a while here.

      Steel mills operate in two distinct ways. The traditional production method occurs at large, vertically integrated mills, which use ovens to heat coal into coke;1 combine the coke with iron ore in a blast furnace to produce pig iron; and then melt the pig iron in a basic oxygen furnace to produce liquid steel. This production process is commonly known as the Blast-Furnace/Basic Oxygen Furnace (BF-BOF) method. The alternate method occurs through “mini-mills,” which use electric arc furnaces (EAFs) to melt steel scrap and, in some instances, use iron pellets to produce liquid steel. Unlike integrated mills, mini-mills do not require coke ovens or blast furnaces. However, some mini-mills use a process called direct reduction to remove oxygen from iron ore with heat from burning natural gas; the resulting product, direct reduced iron (DRI) or sponge iron, is turned into a lump, pellet, or briquetted form that can be transformed into liquid steel in EAFs.2 Once steel is produced in its liquid state, it is cast into rectangular slabs (long billets a few inches on a side) or other shapes and left to cool. Rolling mills then shape the semifinished steel into a variety of products, generally classified as either “flat” products (plate and coils of steel sheet) or “long” products (bars, rails, wire rods). The rolled steel products often undergo additional finishing operations, such as coating, painting, and galvanizing, to produce finished steel. Figure 1 shows the process for manufacturing iron, steel, and finished steel products.

      pulled from a US government thing, seems like most cleaner methods use refined iron. Although from some quick googling, it seems like this is a preparation method for iron ore, so maybe this is just a semantics thing here.

      ok, and some statistics, it seem slike 30% of US production is using vertically integrated mills, or coal based production (presumably) Seems like they’re even cheaper, generally. Which is also a benefit.

      So i guess overall, the steel industry is better than i expected.
