So-called natural gas is bad for the climate.

The article introduces and explains the “Copper Sushi” project, which involves simulating and visualizing the complex, real-time power flow dynamics across the interconnected European electricity grid.

This Joule research article proposes an integrated electrochemical and catalytic process to efficiently convert renewable ammonia into a carbon-neutral liquid hydrocarbon fuel, offering a new route for sustainable energy production.

Some climate optimism was just what I needed today.

Svensk vindenergi.

Kommunala veton och Försvarsmaktens invändningar var de främsta orsakerna till att endast två nya tillstånd gavs för vindkraft på land och till havs i Sverige under fjolåret. Nu hotas den storskaliga utbyggnaden av elproduktionen i Sverige.

Alltså klimatkatastrofen är inte att leka med. Så här kan det inte fortsätta.

So for all the “lol nukez are great and gen IV will solve climate change” on Slashdot 25 years ago we now have… one reactor!

This idea, seeing

ChatGPT and other AI applications such as Midjourney have pushed “Artificial Intelligence” high on the hype cycle. In this article, I want to focus specifically on the energy cost of training and using applications like ChatGPT, what their widespread adoption could mean for global CO₂ emissions, and what we could do to limit these emissions.

Key points

• Training of large AI models is not the problem
• Large-scale use of large AI models would be unsustainable
• Renewables are not making AI more sustainable

“Streaming media is calculated to contribute a surprising 1% of global greenhouse gases, because most regions of the world obtain electricity from fossil fuels to power their data centers, networks, and devices. Streaming large files in large quantities, then, ethically implicates spectators in the warming of the planet. Our research addresses the high and rising electricity consumption of information and communication technologies (ICT), which consume as much as 7% of global electricity (Andrae 2020). Given that globally about 79% of electricity comes from fossil fuels, this means that ICT is responsible for 3.3% to 3.8% of global greenhouse gases (Belkhir and Elmeligi 2018, Cisco 2020b, Bordage 2019). Streaming media – video on demand (e.g. Netflix, Crave), porn, YouTube, games, video conferencing, etc. – contributes more than any other sector to this increase (Cisco 2020).”

“In economics, the Jevons paradox occurs when technological progress or government policy increases the efficiency with which a resource is used (reducing the amount necessary for any one use), but the falling cost of use increases its demand, increasing, rather than reducing, resource use. The Jevons effect is perhaps the most widely known paradox in environmental economics. However, governments and environmentalists generally assume that efficiency gains will lower resource consumption, ignoring the possibility of the effect arising.”
