Say ‘Climate Crisis’

Agreed, especially for gaming PC. On laptops and generic PC I think there could be a bigger swing, but also you’d need a USB port capable of pushing 30w which is not a standard feature by any means in a PC/laptop.

Counter point. Most computer power supplies have a curve to their charging efficiency (somewhere north of 50% load). If your PC is substantially below the peak of that curve, then adding load (the phone) could raise the PSU’s efficiency say from 80 to 85% (I’m making up numbers) which would affect the overall efficiency of the entire PC’s load.

I think your answer is still probably correct, but it’s an interesting nuance to think about.

Side notes: Some PSU’s use gallium, e.g., Corsair ax1600i, though by and large most do not. Also if your in the EU then your working with 220/240v PSU’s which adds more efficiency, but that would apply to the phone charger as well.

Sisal carpet is better than rope for cats is my understanding. There are some places online that sell carpet remnants for cats. You can just hot glue the carpet to a cardboard tube on or an existing cat post.
