How to improve the resilience of power generation from energy intensity perspective? Evidence from the generalized Divisia index approach
(Environmental impact assessment review, 2023)As the share of renewable energy increases in the energy-mix, tracking energy intensity (EI) dynamics and determinants thereof is a significant issue of energy economics related to power resilience. Previous decomposition ... -
Gamtinių dujų magistralinio dujotiekio skirstymo stoties energijos efektyvumo didinimo bei išmetamųjų teršalų mažinimo būdų tyrimas
(Mokslas – Lietuvos ateitis. Aplinkos inžinerija = Science – Future of Lithuania. Environmental engineering, 2023)Pasaulinė energetikos krizė, didėjantis energijos poreikis bei klimato atšilimas įpareigoja ieškoti būdų, kaip atgauti naudingai nepanaudojamą energiją, sumažinti pirminės ir galutinės energijos suvartojimą bei sumažinti ... -
Changing character of town form during the XX−XXI c.: the case of Lithuanian small towns
(Landscape architecture and art, 2020)Although towns are constantly changing, changes may have a major impact on town character. Town character reflects the distinctiveness of town form and there is a risk that town may change unrecognisably. This issue is ... -
