Different Fuels, Different Traits

Did you know that all fuels used for electricity generation have unique properties, with strengths in some areas and weaknesses in others?

Coal
  • High reliability
  • Relatively low cost at the moment but its price may change in the future
  • High CO2 and other emissions
Nuclear
  • High reliability
  • Steady base-load generation on a large scale
  • Virtually zero CO2 and other air emissions
  • Public concern over its safety
Natural Gas
  • High reliability
  • Low CO2 and other emissions
  • Relatively high cost at the moment but its price may change in the future
Renewable Energy
  • Zero emissions
  • High generation cost
  • Large amount of land required
  • Suitable levels of renewable resources may not be available such as in Hong Kong
  • Intermittent nature requires back-up from conventional generation
