The article highlights the differences in cost among different types of energy used to generate power for electricity. Sustainability definitely has been one of the biggest topics around the world, and one of the ways is to save is through renewable energy. According to The Economist, among the four sorts of zero-carbon energy (solar, wind, hydroelectric and nuclear), the nuclear power plants are the most expensive, though it is the most cost-effective technology.

We can also see people within our community putting importance on sustainability. Ranked as one of the greenest cities in the world, Vancouver values the beauty of a healthy environment. Unlike most cities, Vancouver’s public transportation runs with electric trolleybuses. Green Power Buses, which has no engine or transmission, have also been introduced in Vancouver. While not using any diesel fuel, fuel savings alone is up to $60,000 a year (Burritt).

Growing up in Malaysia, I was not exposed to the idea of sustainability until I came to Vancouver. The topic of sustainability itself is very new to me and this week’s topic helped me understand more about sustainability. After reading articles about sustainability, in the long run, sustainability is definitely a way to improve the quality of life. The idea of sustainability should also be greatly marketed in Asian countries, in hopes that they will also develop healthier environments.
