Developing a sustainable plan for Hong Kong is a process that will take many decades to do effectively. The sustainable sources of energy would have to focus around tidal, wave, solar, and wind energy. Ideally, geothermal and hydroelectric power plants make for great sources that are sustainable and economically sound. However, in Hong Kong, these two sources do not possess a future and any chance of prosperity for these industries is unrealistic as discussed earlier. The rivers having don’t have sufficient flow and height; capital costs to create hydroelectric power plants would be a pointless task due to the lack of energy created.
If Hong Kong were to rely on these four sources for their energy they would be in a lot of trouble. Looking back to the green stack we can see that these four categories would provide about 17 kWh per day per person, while the red stack number clearly exceeds the energy provided. For a sustainable plan to be possible, there would have to be restrictions and limits placed on transportation, and heating/cooling for industries and private sectors. The massive amount of energy consumed in Hong Kong can be reduced but not to 17 kWh per day per person. So while it does seem impossible to rely on sustainable resources for 100 percent of the Hong Kong energy, it is very possible to create a sustainable plan for the population. If the people and the businesses keep the topic of conserving energy on their minds then change will happen. It’s tough to say where we will be at ten, twenty, or even a hundred years from now, but a sustainable plan may be the only way to preserve out planet.
