No, essentially 100% of energy used for computation will turn into 'waste' heat.

If you calculate 1000 digits of pi, those digits will not embody any energy.

Just turning chaos into order takes thermodynamic work, but I was wildly off with my percentages. Thinking in terms of an idealized computer that doesn't create heat, but didn't realize how far we were from that.
