Il loro grande problema, non sta ta

Il loro grande problema, non sta tanto nella intrinseca natura, il cui rendimento comunque resta di tipo aleatorio (non c’è sempre sole o vento), quanto nel loro immagazzinamento. Le tecniche moderne si attestano alle batterie elettrochimiche, molto costose ed anche voluminose in rapporto all’energia immagazzinata.

Risultati (Inglese) 1:

their biggest problem is not so much in the intrinsic nature, the performance still remains uncertain type (there is always sun or wind), because in their storage. modern techniques amounted to electrochemical batteries, very expensive and also massive in relation to the energy stored.

Their big problem is not so much the intrinsic nature, whose performance still remains uncertain type (there is always Sun or wind), as well as their storage. Modern techniques attest to electrochemical batteries, very expensive and also large in relation to the stored energy.

Their big problem is not so much in the intrinsic nature, the efficiency of which still remains of type random (there is always sun or wind), as in their storage. The modern techniques abut the electrochemical batteries, very expensive, and voluminous in relation to the stored energy.
