Thoreau
"Where I lived and What I lived for"by Henry David Thoreau is about his experience in the woods. He mentions, "Children, who play life, discern its true law and relations more clearly than men, who fail to live it worthily, but who think that they are wiser by experience, that is, by failure."(Thoreau,1954) He states that children, who play life, live with lightness unlike us, who live with complicated adn seriousness life. I think he wants to say that we need to turn inot simplicity with nature by using less energy resource, as we take off complicated life.Thursday, April 8, 2010

US President -elect Barack Obama gave the first of his weekly addresses to the nation and declared that he mentioned American leadership on climate change.
Economic growth in China
According to this article, China has rapid economic growth about 10% per year and has been fufiiled by an annual energy growth rate of greater than 10% from 2001 to 2005. This in turn has led to the construction of one to two GWe of electrical making capacity per week over the period with the vast majority of the power plants using coal. China has equaled the carbon consumption rate of United States at 6 billion tonnes per year in 2006, far sooner than was expected due to the energy growth. Levine, M. (2008).

How can we reduce wasting energy?

There are lots of ways to reduce our wasting energy in our life through the resources.
1. Turn off when you are not using.
2. Cover pots; thaw frozen foods before cooking; plan meals carefully.
3. Wash full loads; use cold water.
4. Walk; ride in carpools; ride a bike; keep car in good running condition.
5. Short shower instead of deep bath; take shorter shower.
6. Install storm doors; keep doors closed when using heat or air conditioning; install wather stripping.
7. Set at 68 degrees in winter and turn down at night by wearing warm clothes; set at 78 degrees in summer by wearing cool clothes.
8. Close flue when not in use; install glass firescreen that can be closed when fireplace is not in use.
9. Close draperies at night; put shutters, blinds, or drapes on all windows; install storm windows.
10. Do not use several heavy users at the same time.

Energy usage
As fossil fuel energy are making many problems such as changing climate and greenhouse gas emission, many nations and governments suggest other energy resources which are clean, emission free, and renewable energy like solar, wind, and ocean energy by nature. Therefore, through this chart, how energy usage is increasing in each year. According to this chart, the rapid growth of energy usage has increased since 2004 abruptly. In addition, I could know how renewable energy in limelight today.Sunday, April 4, 2010

Hydroelectric power
Hydroelectric power depends on the global cycle of water; "evaporating from lakes and oceans, forming clouds, precipitating as rain or snow, then flowing back down to the ocean." The common method of hydropower is a dam. Basically, water is blocked, so there is only one way that it can go out through turbines as needed to meet energy demands. Today, between 7 and 9% of the United States electricity comes from hydro energy and 19 percent of the total electricity in the world. However, hydropower remains highly controversial because it has bad impact on local land and water resources.

Limited energy
There are lots of sorts of energy around us, such as electronic, fuel, and natural resources. Most energy is created by earth, the storage place of energy. However, the natural resources are limited to use and the people's unlimited wants and comsumption are increasing, as they are decreasing the limited resources and supply. Today, the world encounters new issues about how to save energy and how to make recycled energy, and many countries are trying to find new alternative and renewable energy in limited resources. According to the article, renewable energy now accounts for 9.5 percent of the nation's electricity supply, but it is not enough even with the assistance by government.http://www.nytimes.com/2009/10/18/weekinreview/18galbraith.html?scp=7&sq=alternative%20energy&st=cse
