This thesis explores how renewable energy sources (RES) shape Greece’s economic
performance, focusing on both their direct and indirect impacts on GDP, employment,
trade balance, and regional development. RES have emerged as a major force behind
Greece's economic growth and sustainable development, according to the study, which
uses statistical data from ELSTAT, Eurostat, the Regulatory Authority for Energy
(ΡΑΑΕΥ), the Independent Power Transmission Operator (IPTO), the International
Energy Agency (IEA), and the International Renewable Energy Agency (IRENA) for the
years 2000–2025.
While their percentage of electricity generation surpassed 55% in 2023, above the EU
average, the total installed RES capacity grew from 600 MW in 2000 to roughly 17 GW
in 2024. A 1% increase in RES use results in a 0.13% increase in GDP, according to
empirical research, while full implementation of the National Energy and Climate Plan
(NECP) could increase Greek GDP by 2.5% by 2050. In addition, the energy sector's
Gross Value Added (GVA) has increased dramatically, over 25,000 jobs have been
created, and fuel imports have decreased from €9 billion in 2010 to less than €4 billion in
2024.
The findings demonstrate that RES is an essential component of social cohesion and
sustainable growth. At the same time, the study highlights a number of lingering issues,
including limited energy storage, inadequate grid capacity, and permitting delays. It also
suggests policy measures to hasten the transition, such as boosting energy communities,
integrating RES into the transportation and heating sectors, and expanding energy storage
systems.
In conclusion, the findings show that renewable energy is not only an environmental goal
but also a sound economic strategy for Greece, one that can boost long-term economic
resilience, competitiveness, and energy security.
