  1. Solar Energy Chris Au, Keivan Meshkat Per. 6

  2. History 1767- First solar collector was created by a swiss scientist named Horace-Benedict 1947- Solar powered items became very popular after WW2 1981-82- First solar powered aircrafts and cars created 1986-99- Large scale solar power plants evolve 2012- Record breaking solar plants in China http://exploringgreentechnology.com/solar-energy/history-of-solar-energy/ http://photo-galaxy.blogspot.com/2012/02/horace-benedict-de-saussure.html

  3. Politics • Pros: • No pollution • Very quiet • Able to harness energy in remote places • Efficient in large area of world • Cons: • Initial cost of solar panels • Only generates electricity during daylight • Weather can affect efficiency of a solar cell • Pollution levels can efficiency of a solar cell • http://www.clean-energy-ideas.com/solar/solar-energy/pros-and-cons-of-solar-energy http://1bog.org/blog/the-advantages-of-solar-power-vs-other-renewable-energy-sources/

  4. Physics - Every hour, the sun hits the earth with enough energy to meet global needs for an entire year. - Photovoltaic cells are found on spacecrafts, rooftops, and even handheld calculators. - The cells react when sunlight hits them, knocking electrons loose from their atoms, generating electricity. http://environment.nationalgeographic.com/environment/global-warming/solar-power-profile/ http://www.fsec.ucf.edu/en/consumer/solar_electricity/basics/images/F1_HowCellWorks_401x217.gif

  5. http://en.wikipedia.org/wiki/Solar_power_in_California So. Cal. Production + Use • As of 2012, we had 364 MW of concentrated solar power and 2,259 of photovoltaics • Southern California leads in houses with solar panels installed • Feed-in-tariff allows investors a guaranteed return on investment • By 2016, there will be 3,000 additional MW installed http://en.wikipedia.org/wiki/Solar_power_in_California

  6. National Production + Use • America is a leader in solar energy production and use. The nations’ plants include: • SEGS (California) = 354 MW • Nevada Solar One = 64 MW • Copper Facility (Nevada) = 48 MW • DeSoto Plant (Florida) = 25 MW • The Desert Sunlight Solar farm, under construction in Riverside, CA, will have a capacity of 55 • http://en.wikipedia.org/wiki/Solar_power_by_country#United_States http://graphics.latimes.com/towergraphic-la-me-solar-desert-tg/

  7. Global Production + Use • Today, solar energy produces less than one-tenth of a percent of the global energy demand. • Germany: 32.3 GW • Chinese solar panel production quadrupled from 2009 - 2011 • China has surpassed the entire global demand • Europe has blamed China for dumping solar panels at below-cost prices • http://en.wikipedia.org/wiki/Solar_power_by_country#United_States http://www.energy-guru.com/(S(aglijv2ilfzafubso1meh145))/images/solar_energy_world_map.jpg
