Today's lesson was talking about Energy. One of the world's energy sources would be fossil fuels which is a non-renewable source of energy. It has affected the Earth greatly as the burning of fossil fuels and other non-renewable sources has resulted in global warming, which means that the world's temperature has been increasing every year.
As the people are now more aware of the environmental impacts from all these activities, more and more companies are now changing or at least reducing their usage on non-renewable energy to using renewable energy.
From what Prof mentioned in class, one of the renewable energy, the solar energy, is actually able to provide enough energy for our consumption. But why are we not making use of the solar energy to provide for our use? I think that even though there is this solar panel which is able to acquire energy from the sun, it is not widely used in Asian countries as compared to Western countries. One of the reasons may be that the one-time costs involved in getting the panels are expensive, and due to the resistance to change among Asians.
From the video shown by prof, the westerners made use of the land area for rearing of animals to place their solar panels to obtain their solar energy, i think that they are creative. HAHA.. this is because usually from the impression that i have, westerners are better in making use of the limited space that they have in doing multiple activities. If all the countries are able to make use of their available space to acquire solar energy, i think that the energy consumption would then not depend highly on fossil fuels.
An interesting and informative video that i found related to today's topic:
i think that Singapore is also able to play a part in reducing on non-renewable energy consumption and finding new ways to use renewable sources of energy to help in ensuring the reduction of negative environmental impact on Earth.
Really hope that from what today's session focuses on, the next industrial revolution (from fossil fuels to renewables), will be able to ensure that there will be enough energy for our next and future generations. Shifting from fossil fuels which are non-renewable to renewables, besides ensuring that we will be able to reduce the negative impacts on Earth, also to make sure that there will be enough energy for consumption for our future generations.
