Energy sources are used as fuels. Fuel is burned in machinery to create motion that we use in our cars or heat in a home energy system. When fuels are used for producing electricity, heat or motion causes a generator to rotate, creating electricity for everyday use in homes and businesses. Energy sources can be classified into two types: nonrenewable and renewable. Nonrenewable resources, such as fossil fuels and nuclear material. Fossil fuels were formed from the fossilized remains of tiny plants

important because energy fuels the economy and keeps the world going. Energy can be referred to as many thing and can come in many forms, such as electricity, fossil fuels wind power and hydro-energy. Electrical energy is a main source for keeping the world going short and simple. Lights and plus heating & cooling would not even be an option without any sort of electricity. Transporting many modern good would not even be available without fuel that is produced from fossil fuels. During the 1800s

6/6/2012 “One of the biggest topics for debate in the 21st century is that of global warming and alternative fuels. There is much discussion about whether all the emissions that are produced by factories and automobiles have some effect on the atmosphere. To that end, many people are looking to reduce their carbon footprint. One of the ways to do this is to purchase an alternative fuel car such as a hybrid or electric car. There are many positives and negatives of owning an electrically powered

or Not to Drill Robyn L. Marell HUM/114 May 27, 2012 Esteban Soto To Drill or Not to Drill To drill or not to drill, that is the question. I am of the opinion that we should not continue to drill but look for alternative methods in which to produce energy. Oil prices for a barrel of oil have skyrocketed and rise continuously without regulation when demand is high or the economy is not doing well. Natural gas and the cost of coal have also risen. OPEC has the

the atmosphere. The greenhouse gases stop some of the heat from escaping the atmosphere, which in turn causes change in climate. Some greenhouse gases are neutral but many of them are manmade. With the outstanding industrial development, more fossil fuels such as coal, oil and natural gas are used and burnt, which release carbon dioxide and methane into the atmosphere. Deforestation also produces a lot of carbon dioxide. In fact, many scientists believe that man's activities are making the natural greenhouse
