Students at the university where I worked before retirement researched the environmental impact of PCs. Their conclusion: manufacturing is the most important part of the environmental impact. Using a PC consumes electricity, but even when a PC is kept in use for 10 years, the impact of that is still small compared to the impact of manufacturing.

I don’t think that in this regard, there is not much difference between PCs and laptops.
