The main focus of this lesson is on energy.
Looking at the driving forces of energy consumption, it is easy to point out the relationship between energy and development. However, most of the consumption today are derived from non-renewable sources. This is not a wise decision because one day, we will eventually run out of these resources. Hence, there is a need to explore on renewable energy sources and green biotechnology, which developing giants like China and India are investing heavily into. Prof also highlighted how Brazil, a member of BRIC, is so innovative to think of using sugarcane to supply part of their energy consumption.
Not only that, I think it is time for the world to start questioning the real cost behind non-renewables. Often, our decisions and costing structures are based on economic rationale. However, we have failed to bring in other factors into the equation. In this case, particularly the cost of environmental impacts has not been taken into consideration before. Therefore, people become misled into thinking that these non-renewables are in a way, free because the resources are often found underground and do not cost anything.

It is also very commendable of the European Union (EU) to pledge their commitment to the use of 20% renewable energy sources by 2020. From the video that Prof shared in class, Germany is able to attract many of its citizens to tap on solar energy by providing cash incentives as a form of encouragement. Perhaps, this is a good example that other countries can adopt to ensure a public effort for the benefits of the environment and future generations.
On a serious note, we have to start planning for energy security. It is definitely crucial for us to seek a diversity of sources to depend on, especially for crisis management. More importantly, we need to educate the public and inculcate a sense of social commitment in them towards sustainable energy goals. Ultimately, we only have one Planet Earth and therefore, this is everyone's responsibility.

Overall, 9/10 for this lesson!
