Japan can reach net zero more cheaply with mature renewables than with unproven innovative thermal
New modelling finds a renewable-led transition reaches net zero at 7% lower cost, with stronger economic returns and far less emissions risk than betting on unproven abated thermal.
Nusa Tenggara’s first solar gigawatt displaces Java’s coal, not local diesel
In our model, Nusa Tenggara's diesel fleet already sits idle by 2034. The first gigawatt of solar therefore displaces Java's subcritical coal instead, cutting 1.78 MtCO₂ a year at a net system cost of US$28.4 million (IDR 511 billion), around US$16 per tCO2 avoided
How a Java-Sumatra interconnection could accelerate Indonesia’s decarbonisation
Scenario Builder modelling shows the inter-island transmission link could raise Indonesia’s renewable generation share to 48% by 2040
A Japan powered by 90% clean energy is achievable only with a flexible system
New analysis shows how interconnectors, flexible nuclear and long-duration storage could help reduce wasted renewable energy in Japan’s power system.
Japan could double its clean electricity without much waste
Japan could expand renewable energy to 50% of electricity by 2040 without wasting clean power, according to new modelling of the country’s future power system.
Malaysia data centres: can clean energy keep up?
Modelling shows the Peninsular grid has adequate capacity to 2029, after which coal retirements force a choice between more gas or cleaner alternatives
Struggling to break through: the state of rooftop solar in Indonesia
What satellite imagery reveals about small-scale solar PV installation rates in Southeast Asia’s largest coal system
