Post 10 : Summary

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.

2. 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.

Post 9 : Germany, Country of Green Energy

Country of Green Energy

1. Solar power

    According to news, in July,2013 German solar power plants broke the record for the production of electricity. German solar power plants produced 22 gigawatts of electircity per hour! This achievement is so amazing that Germany absolutely excels at developing solar power. Take a look at the picture below. This picture shows us the world's largest photovoltaic solar park near the city of Senftenberg.

2. Wind power

    Nowadays, there are approximately 20,000 wind power plants in Germany, and these plants provide some 5 percent of electricity in Germany. What's more, German wind power plants not only provide German electricity, but also sell electricity to other countries. In 2012, German wind power industries earned about 6.3 billion Euro! We can easily understand why Germany can make wind power a good by pic.2 below.

3. Obstacle to the development of green energy in Germany

    Just as I mentioned in previous posts, money is always an obstacle to the development of green energy. That is to say, the cost of developing green energy is often enormous so that few countries are willing to invest in green energy. Although Germany's ratio of green energy is the highest in the world, German government did face challenges. Since the cost of green energy is higher than that of fossil fuel or nuclear power, if German government wants to replace traditional energy with green energy, the cost of electricity must be raised. It is estimated that the elecricity price in Germany is four time that of Taiwan. The price is so high that lots of German people oppose the development of green energy. Pic.3 shows German people launching a demonstration against green energy.
