Electrons aren't very nice
They are as cold as ice
Their charge is negative one
With a mass of none
They run around the nucleus all day
With Atomic Obitals hurring them on their way
The periodic table splits into four parts
That have a number of electrons in their hearts
By remembering this poem
Will help you know em
And on a test
You will do your best!

Solar Energy
One of the sources in the world where we get our energy from is the sun. The energy we get from the sun is called solar energy. This is a renewable energy that is used throughout the world. Solar energy can be used to heat your home, generate electricity, heat water, light your home, and dry your clothes. Homes can be heated by using a passive solar design or an active solar heating system. A passive solar design allows the wall, windows, and floors to collect, store, and distribute solar energy in the form of heat in the winter. In the summer it will reject solar heat. An active solar heating system allows either air or water to be heated by solar energy in a collector. Once it is heated, the heat will transfer directly to the space of the house where it is needed. In today's technology there are semiconductors that are designed in cell phones, radios, calculators, etc. The semiconductor will use solar energy to make them function. A semiconductor is a thin layer of material that can produce electricity but requires some effort. In the thin layer, there are electrons lined up. The sunlight will push one of the electrons out of the line. This will cause the other electrons to move forward to fill in the gap. There are other ways to conduct electricity but on a larger scale. Many companies use concentrating solar power plants or photovoltaic panels. Concentrating solar power plants are mirrors that reflect and focus the sun's rays, providing heat, which helps power generators. Photovoltaic panels are usually on rooftops or buildings. Photovoltaic panels collect photovoltaic (solar) cells that can be converted into electricity.
Solar energy is a good renewable energy that the world should use. The sun will never go away and we will always have it to use. Therefore, I support solar energy. While reading an article in "The New York Times" the negative effects of solar energy were discussed. Many feel it is too expensive and would rather use fossil fuels because it is less expensive. However, the burning of coal creates greenhouse gases that damage the environment; i.e. global warming. If the U.S could find an inexpensive way to build the solar panels, then more people would support them. Unfortunately, many businesses are going bankrupt, so the production of solar panels comes to a halt. China, on the other hand, is a dominant player in green energy. They are setting up a lot of solar panels to create solar energy. Since their government is different from ours many businesses are being paid by the government. Companies are getting free land to put the panels on, which is making China a hard competitor to compete with. If only the U.S could make room for solar panels and follow China. Right now, the only state with the most solar panels is California. In the future most states should be using solar energy in order to create a cleaner environment.

Nuclear Reactor Risk Assessment
1. Iran, Mexico, and California have placed nuclear reactors in dangerous areas.
2. The people who built the nuclear reactors did not look at the earthquake risks. Some people did not think it was dangerous to put a nuclear reactor on a major fault line. The major fault lines could move at anytime and disrupt the nuclear reactors. I think people will look at the Japan crisis and think where they should put their nuclear reactors. By doing this they will prevent a potential problem that could happen.
3. I think Groundwater Leaks Reported is the most dangerous. The nuclear power plants have reported a past spill, leak or other inadvertent release of radioactively contaminated water to the environment. This could potentially contaminate the public water, which could make people sick. In Dothan, Alabama there is a Joseph M. Farley unit 1 that has groundwater leaks reported.
4. The nuclear reactors that are dangerously close to the earthquake epicenter are in California. I think they should be shut down considering how many earthquakes California gets. It's only a matter of time when a huge earthquake comes through and destroys them. The reactors that will probably get hit are in San Clemente, California. They are right on the major fault lines and are at major risks.

Energy
http://www.time.com/time/health/article/0,8599,2080176,00.html
The article I chose was about solar energy and the financing for the projects. There has been a 66% increase of solar power installations in the U.S and more are coming. Obama Administration and other companies have given loans to people to put up photovolaic panels on commercial buildings, which will create 10,000 jobs. However, the loans are falling short and the administrations will cut the people off. This creates a big problem for the solar energy projects because if they lose money they will take a step backward. Many companies want solar energy panels but the green groups will have to work faster to keep their loan.
