Solar Energy Essay -- Energy Sources, Solar Power

Someday, our energy sources are going to run out. What will we do? What can we do? Our major source of energy now is fossil fuel. If that were to run out, there must be an alternate way to get energy. Because of this problem, there has been a lot of research going on. Through that research, alternate ways to get energy have been developed. They include wind energy, solar energy, nuclear energy, tidal energy and many more. In this paper I will focus on the aspects of solar energy. I will look at the history of solar energy, cover the advantages and disadvantages of solar energy and then finally I will talk about the concept of solar energy (how it works) and ways that solar energy can be used in your everyday life. First let’s look at the history of solar power. It has been more than a century ago that solar power was first looked into. Some people believe that the reason for alternate energy sources came in the 1970’s when there was an energy crisis. But according to history, the first look at alternate energy sources came when a scare of running out of fossil fuel came about. Many different things were looked at, but solar power somehow was the one that was looked at the most seriously. Once solar power was focused on, years later, there were ways that were invented to obtain the radiation from the sun and use it to make things work. However, the development of solar power faded when World War I came along. After the war, energy was in demand and therefore, solar power took a back seat in science. Fossil fuel still remained the main source of energy at that time. Most of the credit for solar energy should go to the man by the name of Auguste Mouchout.

The most recent major outbreak in 2010 involved Salmonella-contaminated eggs from several U.S. producers that have caused the recall of over 500 million eggs. Contamination can come from animal or human feces that contact the food during its processing or harvesting. New data about types of food contamination. 3)What is an example of a real life outbreak of this foodborne illness in the United States?
