The document discusses renewable energy sources and their potential in Singapore. It notes that while Singapore receives abundant tropical solar energy, the limited wind speeds restrict wind power potential. Geothermal and hydroelectric energy sources are also insufficient due to Singapore's geography. Biomass is mostly used for industrial purposes currently. The document outlines Singapore's energy consumption and sources, with the power grid relying heavily on natural gas imports. It suggests harnessing more renewable sources and adopting lifestyle changes to differing energy landscapes could help address Singapore's energy issues going forward.
