The revised plan sets out to reduce greenhouse gas emissions by-58% by 2030, compared to the EU goal of -55%, while the contribution of renewables to the electricity mix was set at 75.7% compared to the EU target of 69%. Looking back at progress six years on, the“de-lignitisation” process is well underway, with the last coal-burning plants due to shut or switch to natural gas in the coming year, while Greece ranks as one of the most attractive markets globally for renewables investment(EY 2024). Despite these headline successes, however, Greece scores poorly in terms of meeting the broader green transition targets(EEA 2025, CCPI 2026). Several factors contribute to Greece’s disappointing overall performance. The increasing reliance on natural gas and lack of progress in introducing electricity storage are slowing down the decarbonisation of the power sector. Advances in sectors such as industry, transport and buildings have been even slower. Added to this, the recent reactivation of hydrocarbon exploration, combined with diplomatic efforts by the Greek government to relax EU climate targets, offer tangible signs of the top-level change in policy direction which has taken place since 2019 and is set to further compromise the green transition. Renewables stalling Greece continues to set ambitious targets for renewables, and has made some notable progress in this area; however, it has been less successful in lifting constraints on the sector, while a parallel support for natural gas undermines progress in reducing emissions. In 2024, renewables(chiefly wind, photovoltaics and hydro) accounted for 51% of all electricity generated and for 25% of total energy consumption across all sectors(EUROSTAT 2025). Despite RES generation increasing at an average rate of just under 10% for the past decade, the growth trend is not sufficient to hit the national targets of 75.7% of electricity generation and 43% of total energy consumption by 2030 (see Figure 1). Is the Greek green transition running out of power? 2
