An activity I attended in the first college year I was selected as one of the 36 participants from the 400 applicants for the program mainly held by the Taiwan Institute for sustainable Energy. I was able to explore different sustainability issues that human face these days by the talks given by many experts from different fields. The issue that concerns me the most is the usage of renewable energy around the world. How to build a sound system for renewable energy usage and how do they compete with other sources of energy still remain a huge issue now. I want to be one of the people who can solve this problem. Moreover, during these 4 days, my three team members and I analyzed the Sustainable Development Goals report of Germany, and shared our analysis in the last day. Germany’s strategies for protecting the environment has been fascinating me since then. Any corrections will be greatly appreciated!!!
