I think you aren't considering the embodied energy spent in
manufacturing electronics. It is usually way higher than the energy
spent in usage. See

Quoting from the article,

--8<---------------cut here---------------start------------->8---
The embodied energy of the memory chip alone already exceeds the energy
consumption of a laptop during its life expectancy of 3 years
