Week 3: Understanding 'Research' (part 2)

#3: Alternative Energy Sources:
Nuclear Energy:
Nuclear power station use nuclear fission to generate energy by the reaction of uranium-235 inside a nuclear reactor. The reactor uses uranium rods, the atoms of which are split in the process of fission, releasing a large amount of energy. The process continues as a chain reaction with other nuclei. The energy heats water to create steam, which spins a turbine generator, producing electricity.
Tidal power generation:
Tidal power can be extracted from Moon-gravity-powered tides by locating a water turbines in a tidal current, or by building impoundment pond dams that admit-or-release water through a turbine. The turbine can turn an electrical generator, or a gas compressor, that can then store energy until needed. Coastal tides are a source of clean, free, renewable, and sustainable energy.

  1. Do remember to localize the context! Remember we are looking at such information from Singapore's point of view, so might probably not require nuclear, unless you can explain the rational further.
