Electric turbos are amazing and F1 should push for efficiency, as that's way more relevant than "synthetic fuels" imo. Something to consider is that as long as cars are fueled for the whole race, engine efficiency also reduces weight. Per this article

In the V8 era, thermal efficiency peaked at 29%. With the introduction of the V6 turbo-hybrids in 2014, that figure leapt almost immediately to around 40% - and it now stands at over 50%.

If efficiency drops from 50% to 40% for example, because of the removal of MGU-H, engines will need 25 kg more fuel to deliver the same amount of energy.
