True, technicaly it means a fat zero using high performance ic engines as the prime mover but energy recovery has to be done, there is no alternative way to go if ic engines are to be retained.
Electric racing will be the future, it just depends how long motor heads can prevent development and carry on damaging the planet. F1 will help to expose this more and more as time goes on.
In terms of energy and resources wasted, the hybrid drivetrains are worse than the normal combustion ones, because building these batteries that only last some thousand kilometers (in that hundreds of charging-cycles) is very costly.
F1 in general is large indulgence (e.g. the massive amount of CFRP parts produced for each car) and overall using a little bit less fuel doesn't make much difference, introducing a complicated material-intensive new system does.
As an engineering challenge (maybe to benefit roadcars) it does not make much sense either, most aims for a racing system diverge massively from road use (cost, lifetime, temperature operating window...).
After all, it is a PR stunt to make F1 look greenish, and motorsport is not supposed to be green (the motorhomes use more fuel than the cars for a race weekend). Electric racing will not work in the near future, with the systems being more expensive, heavier and less powerful than ICEs.
