Q & A

What is the main cause of climate change according to the script?

The script indicates that human actions are the main cause of climate change, leading to global warming, rising sea levels, and more frequent and intense extreme weather.

What is the solution proposed for decoupling growth from emissions?

The script suggests a new industrial revolution that uses clean energy and innovative strategies to reduce emissions while still allowing for economic growth.

How does the floating solar farm in Singapore contribute to reducing carbon emissions?

The floating solar farm in Singapore can power up to 16,000 HDB flats and offset 32 kilotons of carbon emissions, which is equivalent to the energy needed to run the country's five local water treatment plants.

What is the potential of solar energy according to the script?

The script highlights solar energy as one of the cheapest and most accessible sources of energy, with the potential to be integrated into various surfaces like buildings or vehicles, expanding its footprint.

How does geothermal energy work and what is an Everloop?

Geothermal energy is harvested by drilling deep underground to access heat, which is then used to generate electricity. An Everloop is an innovation that uses a series of multilateral wellbores to circulate fluid, which is naturally heated by the earth, making geothermal energy more accessible and scalable.

What is the advantage of using professionals from the oil and gas industry in the green energy sector?

The script mentions that professionals from the oil and gas industry can redeploy their existing skills in the green energy sector without needing retraining, contributing to the green revolution.

What is nuclear fusion and how does it differ from nuclear fission?

Nuclear fusion is a process where two heavy forms of hydrogen are fused to form helium, releasing energy. Unlike nuclear fission, which has a bad reputation due to long-lasting waste and accidents like Fukushima and Chernobyl, fusion has different radiological hazards and is considered a safer and more sustainable source of power.

How does the centralized cooling system in Singapore's Marina Bay Financial District work?

The centralized cooling system works by chilling water on rooftops using solar panels, then piping the chilled water to homes where it is used to create cool air, making cooling more efficient and reducing energy consumption.

What is green hydrogen and how is it produced?

Green hydrogen is hydrogen created from renewable energy sources. It is produced using a solid oxide electrolyzer cell, which splits water into hydrogen using electrical power derived from renewables, resulting in no carbon or harmful toxins being emitted.

How does Nestle's renewable diesel differ from fossil diesel?

Nestle's renewable diesel is made from waste and residues and releases 90% less greenhouse gas emissions over its life cycle compared to fossil diesel. It is a drop-in solution, fully compatible with diesel engines, and can help decarbonize heavy-duty transportation.

What is the challenge with sustainable aviation fuel (SAF) and how is it being addressed?

SAF is currently more expensive than conventional jet fuel, which prevents wider adoption. Airlines like Singapore Airlines are trialing SAF and aiming to increase its use to achieve carbon neutrality by 2050, hoping to stimulate demand and lower costs.
