Our New Hope
1. Life without fossil fuel
Since the Industrial Revolution, people on earth have tried every possible way to take advantage of fossil fuel. We have done a great job making our lives more convenient and establishing a very advanced civilization. However, the amount of fossil fuel is limited, that means someday we won't be able to live a conveneint live like now. It seems that life will be very tough in the future, but there is a hope, green energy.
Seeing lots of problem caused by using fossil fuel, such us global warming, rising sea level and air pollution, I start to think about a qusetion. Where does energy come from before the discovery of petroleum? The answer is our mighty sun!!! Green energy such as wind power, wave power and solar power all come from sun.(see this idea in post 6) The sun is estimated to live for another 5 billion years, so it is a sustainable energy source for us. Our goal is to figure out how to live a life without fossil fuel.
pic.12. The most promising new energy-solar power
Among all green energy, I think solar power is the most promising one. Isn't it a brilliant thing that a cell can turn light into electricity? To support my opinion, let me show you some advantages of solar power. First, it doesn't emit any carbon dioxide which change our climate drastically. Second, it is sustainable because our sun will be there for a very very long time. Last, it is absolutly safe.
