Geothermal energy What is it?? - energy that comes from the ground; power extracted from heat stored in the earth - It was formed by the decay of minerals and forests several years ago - heat is continuously produced inside the earth http://www.conserve-energy-future.com/GeothermalEnergy.php

Geothermal energy Advantages • Renewability • Earth’s core is always going to be heated • As long as there is a way to extract the energy from the heat, the energy will always be available Alex Mayada, Chris Bartlow, Tim Fisher, Lauren Pawling. Geothermal energy. http://klemow.wilkes.edu/KMK.courses.html
Geothermal energy Advantages • Smaller carbon footprint and environmentally friendly • Remarkable difference of environmental effects compared to fossil fuels • Most hardware used to extract geothermal energy is underground • Minimal use of surface (http://www.geothermal.nau.edu/about/enviroment.shtmlNorthern Arizona University. 2009 Oct 27) Alex Mayada, Chris Bartlow, Tim Fisher, Lauren Pawling. Geothermal energy. http://klemow.wilkes.edu/KMK.courses.html
Geothermal energy Advantages • Lower cost • Easy to operate • Open up economy • Much more efficient use of land (http://www.geothermal.nau.edu/about/enviroment.shtml> Northern Arizona University. 2009 Oct 27) Alex Mayada, Chris Bartlow, Tim Fisher, Lauren Pawling. Geothermal energy. http://klemow.wilkes.edu/KMK.courses.html
Geothermal energy Disadvantages • Fluids drawn from the deep earth carry a mixture of gases • Pollutants contribute to global warming and acid rain • Construction of Plants can adversely affect land stability • Sources may hold trace amounts of toxic chemicals/mineral deposits • Loud Noises • Initial start up cost (expensive) Alex Mayada, Chris Bartlow, Tim Fisher, Lauren Pawling.

Solar Energy The ultimate energy resource • Originates with the thermonuclear fusion reactions occurring in the sun. • Represents the entire electromagnetic radiation (visible light, infrared, ultraviolet, x-rays, and radio waves). Bhavik Shah, Solar Energy: The Ultimate Renewable Resource, http://www.physics.rutgers.edu/
Solar Energy Advantages • Ultimate and free resource (sun) • Does not harmful environmental (no emission gas) • Can be used in remote areas • make absolutely no noise at all • Very little maintenance is needed
Solar Energy Advantages • Comparative life-cycle CO2 emissions http://www.ucsusa.org/clean_energy/our-energy-choices/renewable-energy/environmental-impacts-solar-power.html
Solar Energy Disadvantages • High initial installation cost of solar cell and solar panel • Electricity generation depends entirely on a countries exposure to sunlight • Solar energy is a diffuse source. To harness it, we must concentrate it into an amount and form that we can use, such as heat and electricity.
Solar Energy How much solar energy can be absorbed? • The surface receives about 47% of the total solar energy that reaches the Earth. Only this amount is usable. http://www.physics.rutgers.edu/~kotliar/honors/honsem02/somalwar/HonSem02

Solar Energy Concerns associated with PV and Solar Cell • Heavy investment. • High-latitude areas receive relatively little sunshine. • Solar unreliable at night, during winter, and during cloudy periods. • Storage difficult; relies on batteries that may leak chemicals. • Some PV cells use heavy metals - toxic and difficult to recycle. • Solar farms require much land, currently between 5 and 10 acres / megawatt. • http://klemow.wilkes.edu/KMK.courses.html
