Nvidia's 900 tons of GPU muscle bulks up server market, slims down wallets The server market for the near future is going to be about GPUs, GPUs, and more GPUs, according to Omdia. The market researcher estimates the volume of Nvidia H100 GPUs alone shipped during calendar Q2 added up to more than 900 tons in weight. This headline-grabbing figure comes from the company's latest Cloud and Data Center …
"Datacenters are now responsible for 2.5 to 3.7 percent of all carbon dioxide emissions, Dunning claimed, and adoption of AI is projected to grow at a 37 per cent compound annual growth rate (CAGR) between now and 2030."
Everyone has to come to terms with a small matter of an inappropriate term being used to describe the ongoing climate change debate; carbon dioxide emissions do not create heat. Yes carbon can be used to try and describe the trend of the transfer of heat production from burning fossil fuels; except that other than wind farms, and hydraulic powered generators; every major form of electricity production, coal, gas, wood chips and nuclear, and even the proposed fusion reactors, are all using the same heat engine technology that can only deliver ~35% efficiency. Here in the UK each of the two nuclear reactors being built at Hinkley Point will create 4524 MW of heat to generate 1630 MW of electricity. https://en.wikipedia.org/wiki/Hinkley_Point_C_nuclear_power_station
So the total heat input to the local environment is a continuous 5.8 GW, mostly into the surrounding sea. Now add the total excess heat output from every existing nuclear reactor powered electricity generation. Cutting carbon dioxide emissions by transferring their heat emissions to nuclear, as a green solution is an intellectual dead end. That has to include the electrical energy input to the production of Hydrogen.
The challenge this presents, requires the total elimination of any form of energy production using any form of heat engine as the means to produce energy.
