AI climate impact may be smaller than feared but Canada must watch local energy use

A new analysis suggests the total climate impact from AI data centers may be lower than earlier worst case projections. But the article warns that Canada still needs to pay close attention to where those data centers plug in. If they connect to grids still running on fossil fuels, the local emissions picture changes fast. The piece looks at how efficiency gains in hardware and cooling systems could keep total AI energy demand from spiking as high as some forecasts claimed. But it also notes that Canada's grid mix varies a lot by province. A data center in Quebec running on hydro looks very different from one in Alberta drawing from gas. The local energy picture matters more than the global average when you are talking about real emissions. Worth a read if you follow data center siting or provincial grid policy.
