What would be the best source of energy for Hong Kong to use?

Question

For example, if the people of Hong Kong decided that they do not want to import any of this electrical energy from Asia. Instead they want to generate all their electrical energy in Hong Kong

Answer 1

As tightly packed as Hong Kong is, nuclear is the only choice, the harbor is needed for shipping so you can't put enough solar or wind generators out there to power something as energy intensive as Hong Kong.

Answer 2

Well tidal energy seems like a good option But the cost and maintainnance also have to be taken into account. Nuclear is another option.
