Talking Points

Recent interactions between the hosts and their guests.

S3E4: Is the ASEAN chairmanship that powerful? Can Singapore push the green agenda?
Q: Do you think other ASEAN countries see the value of having an ASEAN Power Grid?
Some countries may prioritize electrifying their own underserved communities before exporting power. Microgrids, falling renewable technology costs and battery storage could help deliver local access, while cross-border infrastructure still needs financing and bankable projects.
S3E4: Is the ASEAN chairmanship that powerful? Can Singapore push the green agenda?
Q: What power does ASEAN chair really have?
The chair steers ASEAN's agenda for the year, but member states have equal say. It must build consensus and use persuasion, since other members can resist an agenda they do not support.
S3E2: Haze and a Godzilla El Nino: How is Singapore preparing?
Q: What are the solutions being piloted for people who need to cope with heat without air-conditioning?
The speakers discuss cool paint on housing blocks, air coolers tested in rental homes, architectural changes to improve airflow, and fan-equipped jackets for outdoor workers.
S3E2: Haze and a Godzilla El Nino: How is Singapore preparing?
Q: What exactly is El Niño?
Ang Qing explains that El Niño is the warm phase of the El Niño-Southern Oscillation, a natural climate phenomenon that influences sea-surface temperatures and rainfall patterns.
S3E3: What if Singapore had a nuclear reactor, where’d it be?
Q: How can we, what would it take to assure people or convince people that nuclear plants are safe?
Low recommends communicating scientific facts clearly and repeatedly, listening to public concerns, and involving trusted scientists and professionals who can address specific misconceptions and legitimate questions.
