This episode is talking about “Pragmatic Long-term Energy Pathways”. IEEJ has participated in the production of a report by S&P Global, “Multidimensional Global Energy Pathways.” Mr. Terazawa believes the report presents a realistic, credible outlook for the future of energy, based on realities rather than driven by predetermined outcomes, which can provide an actionable basis for decisions by policymakers and investors. He will introduce the essence of the report.

This episode is talking about “The full cost of deploying variable renewable energy must be incorporated”. Mr. Terazawa will explain why integration costs need to be included when assessing the full cost of variable renewable energy (VRE), including backup, storage, curtailment, and grid expansion costs. He will also discuss the relationship between VRE penetration and power system costs in Japan, including the cost-optimal VRE share for 2050 and the role of demand response, batteries, nuclear power, and thermal power as backup.

This episode is talking about “Update: Impact of Iran Crisis and Responses by Japan”. Nearly six months have passed since the attack on Iran started. While the outlook for the Iran crisis is still unclear, Mr. Terazawa will provide an update on the impact of the crisis on Japan and the responses by Japan to enhance its energy security.

This episode is talking about “Energy Security Enhancement could be affected by Australia’s LNG Policy”. Drawing lessons from the Iran crisis, the discussion explores why strengthening energy security is a growing priority for Asia. It examines Australia's role as a key LNG supplier, the potential impact of its proposed domestic gas reservation policy on future LNG investment, and why investment-friendly policies could deliver long-term benefits for both Asia's energy security and Australia's economy.

This episode is talking about “Asian Energy Crisis” requires more attention and unique responses. While the world focuses on a global crisis, Developing Asia is being hit much harder than Emerging Asia. Mr. Terazawa shares his thoughts on why financial aid alone isn't enough and why a physical supply of energy is essential. He also addresses the critical need for stronger regional energy security and AZEC's role as a foundation for this transition.

This episode is talking about “Japan’s exposure and responses to the Iran Conflict”. While the prospect of the Iran conflict is hard to predict, Mr. Terazawa will share with the listeners the exposure and responses of Japan to the conflict.

This episode is talking about “The start of ETS in Japan”. Japan’s new ETS, launching in April and covering 60% of national emissions, introduces a growth‑oriented design with realistic allowance allocation and free credits through FY 2033. With early energy‑transition support, a price band to spur investment, and limited carbon‑credit offsets, the system also creates new opportunities for global low‑carbon solution providers.

This episode is talking about “PM Takaichi’s Triumph”. PM Sanae Takaichi won the Lower House election, largely due to her strong popularity and the opposition parties’ weaknesses. Her victory enables her to pass legislation without relying on opposition support. While her administration is expected to maintain the overall direction of existing energy and climate policies, the mega‑solar sector may face notable impacts.

This episode is talking about “Significant Progress in Nuclear Power in Japan”. Local governors have approved restarting KK Unit 6 and Tomari Unit 3, signaling growing momentum for nuclear power in Japan. While this marks a major step, challenges remain for further restarts and reactor replacements.

This episode is talking about “Various Pathways for Decarbonizing Road Transport in the Global South”. BEVs are not the only solution for the Global South. In Indonesia, their life-cycle CO₂ emissions are currently the highest among powertrains and may remain so, while deployment costs must also be considered. Brazil benefits most from combining biofuels with hybrids, and biogas is a practical option for India. In some regions, climate conditions make BEVs less suitable, so road transport strategies should reflect local circumstances.

This episode is talking about “The integration costs of variable renewable energies must be considered”. LCOE alone doesn’t reflect the true cost of power. When integration costs of variable renewables are included, solar becomes expensive at high penetration levels. In Japan and ASEAN, total costs rise sharply beyond 34–50% VRE. A cost-effective energy mix must consider these integration costs.

This episode is talking about “Energy Efficiency of AI & Energy Efficiency by AI”. How AI is driving up energy demand—especially in data centers—and how improving its efficiency could help reduce global energy use. With the right strategies, AI could boost energy efficiency across industries by 2035, but it will require training, incentives, and better data practices.

This episode is talking about “Global Energy Outlook: Strong Demand Driven by India and ASEAN”. IEEJ’s Global Energy Outlook outlines rising energy demand—especially in India and ASEAN—alongside strong global gas use and ongoing coal expansion. While deep CO₂ cuts by 2050 are possible with technology, the 1.5°C goal is unlikely. Achieving 2°C remains feasible with more effort, and climate adaptation is increasingly vital.

This episode is talking about “Japan’s International Initiatives in the Energy Sector”. While Prime Minister Shigeru Ishiba has been struggling with political difficulties following the defeat in the Upper House election in July, leading to his announcement on September 7 to resign from the Presidency of LDP, the ruling party, he has also been leading Japan in a series of international energy initiatives.

This episode is talking about “Japan’s Politics Update”. This episode follows up the developments since the Upper House election held on July 20th. With the ruling coalition parties’ defeat, politics is becoming very fluid. Mr. Terazawa will explain Japan’s political situation, which is increasingly complex and confusing.
