Technology and Environment Intersect: Datacenters, AI, and Wildlife

Ireland's Datacenters Guzzle 23% of Country's Electricity, While AI Innovations Emerge

Ireland's datacenters have increased their electricity consumption by 10% in 2025, now accounting for nearly a quarter of the country's metered electricity use, while the world of artificial intelligence continues to advance with new innovations in sparse attention kernels and JAX types.

Several frontier models in AI have adopted sparse attention to speed up their inference, and a recent development has introduced the world's first performant open-source training kernels for Minimax Sparse Attention. This innovation has the potential to greatly accelerate AI training, making it more efficient and accessible.

Meanwhile, Ireland's datacenters have become a significant consumer of electricity, with their share of the country's metered electricity consumption rising to 23% in 2025. This has raised concerns about the environmental impact of these energy-hungry facilities.
