The role of clean energy

After reading the chapter 6 I learned that increasing energy efficiency is a direct way to against climate change. Energy efficiency in climate change is the most significant role at present situation. My family have taken part in energy efficiency like most of Americans. We recycle bottles, papers, and water. I use bank statement letters as sketch papers when I was doing math problems. I would turn off all the electric after leaving home. World has changed a lot in the past few years. I have just been to the New York International Auto show last Sunday, and I have noticed that more and more hybrid cars were made from different companies. Green energy car will become the mainstream in the future.
