The increased awareness of the potentially devastating impacts of global warming has brought the issue front and center. A new alternative energy market has spawned numerous companies that manufacture a variety of alternative energies such as solar energy and wind energy. Concerned citizens and corporations looking to take a stance and transition into alternative fuels have a wide range of alternative fuels to choose from. While it is widely believed that alternative fuels do not release carbon dioxide into the atmosphere; manufacturing and transporting these fuels and energy sources require the use of fossil fuels. It is our mission to investigate the carbon dioxide released by the production of each of these fuels and the carbon it offsets when compared with the use of fossil fuels. We hope provide a greater insight into the carbon footprint of alternative energies to facilitate the transition to an alternative energy source.

Solar Energy - The sun drives our universe and more specifically our planet. All types of energy in our planet is ultimately created by the sun so solar energy is the most pure source of this energy. Solar energy is the harvesting of the heat and the energy of the sun. There are different ways to capture the energy of the sun but the most effective is photovoltaic cell. Solar energy is captured in solar panels which are comprised of semiconductors, substances that conduct electricity, such as crystalline silicon.

Wind Energy - Wind is a form of solar energy. Winds are caused from air heated by the sun. The sun heats the molecules in the air. The hot air molecules rise up and cold air replaces the hot air, thus creating wind. Wind is harnessed into electrical energy through turbines. A turbine consists of a 30-foot shaft with two or three propeller-like blades attached to the top. The turbine, attached to a generator, uses the wind to generate electricity. The electricity can then be used to power buildings and electrical appliances.
