Public Speaking / Interviews

Nikos Mantzaris, Policy Analyst and co-founder at The Green Tank, was featured on Naftemporiki TV’s Index programme, hosted by Christina Kousouni and Michalis Mastorakis, in an in-depth discussion on high electricity prices and Greece’s energy policy choices.

Until recently, Greece was on track to achieve its CO₂ emissions reduction target of 55% by 2030, thanks to lignite phase-out and the rapid expansion of renewable energy. However, Nikos Mantzaris, energy policy analyst and co-founder of The Green Tank, warns that power sector emissions in 2025 are expected to reach 15 million tons, compared to the 10.2 million tons projected in the National Energy and Climate Plan (NECP).

Recent government announcements on hydrocarbon exploration in the Ionian Sea have been presented as a pathway to Greece’s energy autonomy. However, as Nikos Mantzaris, energy policy analyst and co-founder of The Green Tank, points out on Inside Story, the available evidence shows that this choice runs counter to both the country’s climate commitments and the public interest.

During the latest episode of ECONEWS by DEI with Korina Georgiou, Ioanna Souka, Energy Policy Analyst at The Green Tank, commented on Greece’s performance in the Climate Change Performance Index 2026, where the country ranks 30th out of 63, dropping eight places compared to 2025.

In the latest episode of ADMIE’s podcast “Stin Priza (Plugged In), with journalist Mantalena Piou,” Nikos Mantzaris, policy analyst and co-founder of The Green Tank, explains why renewables are driving down electricity generation costs, yet consumers have not yet seen these savings reflected in their bills. As he notes, the parallel rise in gas-fired generation, the lack of sufficient storage infrastructure, and the absence of incentives to shift demand to low-price hours are undermining the economic benefits of renewables.

Speaking on the show “Radio City” on radio Athens 9.84, Ioli Christopoulou, Policy Director and co-founder of The Green Tank, highlighted the critical situation of sperm whales in Greek waters, focusing on the Kythira Strait and efforts being made to prevent ship strikes through the SAvE Whales project.

Montel News featured comments by Nikos Mantzaris, policy analyst and co-founder at The Green Tank, on the sharp rise in renewable energy curtailments in Greece during 2025.

In the latest episode of Lifo Podcasts titled “Social Climate Fund: Real support or a missed opportunity?”, Ioanna Souka, energy policy analyst at The Green Tank, talks with Dina Karatzou about the strengths and weaknesses of Greece’s Social Climate Plan. They discuss the social impacts of ETS2 and how Greece can make use of up to €15.5 billion to ensure a just and sustainable energy transition.

Ahead of the announcement of October electricity tariffs, Nikos Mantzaris spoke on ERT with journalist Katerina Christofilidou about energy prices.

Nikos Mantzaris, political analyst and co-founder of The Green Tank, appeared on ERT3’s “Synora” show to discuss Greece’s progress in phasing out coal and the significant delays in the Western Balkans.

At a time when the focus is on lowering energy costs for the country’s large industries, small and medium-sized enterprises (SMEs) must not be left behind. Energy communities offer a crucial tool to support them, enabling collective energy production and consumption, which lowers costs and strengthens financial sustainability. According to the article by Christina Zafeirouli on energygame.gr, with contributions from Ioanna Souka, there are already examples of energy communities in Greece, the most recent being the Prespes Renewable Energy Community (PREC).

Ioanna Souka, Energy Policy Analyst at The Green Tank, spoke on the radio program Euranet and to journalists Nikos Andritsos and Korina Georgiou, about the just energy transition and the crucial role of citizens. As she stressed, “for the energy transition to succeed, citizen participation is essential.”

The energy transition is moving forward, but for it to be successful and fair, it needs genuine public participation and social acceptance. This was the central message of Ioanna Souka, energy policy analyst at The Green Tank, in her interview on Naftemporiki TV.

The importance of energy democracy and the need for a socially just energy transition were highlighted by Ioanna Souka, Energy Policy Analyst at The Green Tank, during her participation in the online event organized by the citizens’ initiative O Kosmos on July 24, marking the 51st anniversary of the restoration of democracy in Greece.
