Christopher 1 Taylor Christopher Professor Nichols SP12 PSC103 SEC1 April 15, 2012 Alternative Energy Sources Throughout the world, one can observe multiple alternative energy sources. These are en- ergy sources that are of usable energy with the intention of replacing fuel sources to avoid the undesired result of the replaced fuels, particularly carbon dioxide. Composed of two oxygen atoms covalently bonded to a single carbon atom, this naturally occurring chemical compound is considered by many to be the primary factor of global warming. [1, Alternative Energy] Some of the most common forms of alternative energy sources used to prevent emitting more carbon di- oxide are solar energy, wind energy, geothermal energy, biofuel and ethanol, and hydrogen. Solar energy is electricity generated by radiant heat and light from the sun. This form is divided into two types known as thermal and electric energy. Depending on how the solar energy is captured, converted, and distributed, solar technologies are classified as either active solar or passive solar. [2, Legistlature] These technologies include solar heating, solar photovoltaics, sol- ar thermal electricity, and solar architecture. Active solar can be achieved by the use of photovol- taic panels and solar thermal collectors to harness the energy. On the contrary, passive solar can be observed through the positioning of a building toward the sun, the selection of materials con- taining favorable thermal mass or light dispersing properties, and the designing of spaces that circulate air naturally. Solar energy is capable of increasing sustainability, reducing air pollution, decreasing the expenses used to mitigate climate change, and retain fossil fuel prices from in- creasing furthermore.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
