Green Stack: Geothermal

Unfortunately for Hong Kong, geothermal energy is another unfeasible source of renewable energy. Due to geological constraints and such a dense population, geothermal energy is a renewable source that would not work in Hong Kong. Assuming hot dry rock resource was similar to the UK as presented in McKay's book, "Sustainable Energy Without The Hot Air", The UK has a population of only about 43 people per km^2, while Hong Kong has about 6250 people per km^2. The UK presented only 0.13 kWh/day per person with a much less dense population, revealing little hope for Hong Kong. In addition when conducting research, every site stated that geothermal energy is not plausible for Hong Kong.
