Do data centers only seem bad for the climate because we can see them?
5 days ago
- The climate impact of emissions is often invisible, making visible sources like data centers seem disproportionately harmful compared to hidden sources like individual microwaves.
- Data centers are more energy-efficient than distributed personal computing, similar to how a hypothetical national microwave would be more efficient than individual ovens, but visible concentration draws criticism.
- People make three mistakes: not comparing benefits per emissions, favoring 'normal' but less efficient alternatives, and focusing on visible targets while ignoring larger but invisible emissions from sectors like cement or livestock.
- Globally, data centers use 1.5% of electricity and are responsible for 0.48% of emissions, making them relatively small contributors compared to other industries that lack visible 'evil buildings.'
- Data centers are valuable tools that can help address climate change through optimization, and the priority should be greening the energy grid rather than cutting computing.
