Dainius Kreivys, in the context of Lithuania's energy security, highlights the significant weaknesses of an energy system inherited from the Soviet Union, which emphasizes large power plants and central facilities. He points out that while this model may have worked during peacetime, it presents glaring vulnerabilities during wars or sabotage situations. The interdependence on a few critical nodes means that damaging just one can disproportionately impact the entire nation's energy reliability.

To address this issue, Kreivys advocates for a shift towards a decentralized energy system, which would consist of numerous smaller, interconnected production, storage, and distribution points. This model is proposed as being more resilient, as the operation of the energy network would not be reliant on a single entity or transmission path. Such decentralization would promote energy independence and reduce the risks associated with attacks on critical infrastructure.

Under Kreivys's tenure as Lithuania's Minister of Energy in Ingrida Šimonytė's government, significant progress was made toward developing this decentralized model. By laying the groundwork for a robust network of smaller energy systems, the government aims to ensure that even if one part of the system is compromised, the remaining networks can continue to operate effectively, thus enhancing overall national energy security.
