One of the aims of this article is to explore various proponents of the energy scene in Hong Kong. However, the primary focus is at why Hong Kong should potentially move to a more sustainable and renewable energy model where they will be successful in minimizing costs and maximizing efficiency and utility, and how they could do it. Through analyzing Hong Kong’s current sources of energy, we will be able to ascertain the efficiency of any given source and also determine the opportunity cost of the investment in these expensive energy sources. By critically thinking about the issue and the crux it’s based out of, we can deter the fundamental need for this solid change, which will be highlighted by the advantages entailed and their deeper implications. By envisioning this future for Hong Kong, it is easy to see it as a foundation to a vision considered greater than realism - Earth running at 100% using sustainable energy.
