Exploring Solar Energy: CSP and PV Technologies, Benefits, and Challenges

This comprehensive overview explains solar energy, focusing on its two main technologies: Concentrated Solar Power (CSP) and Photovoltaics (PV). CSP harnesses sunlight to generate steam for power, while PV converts sunlight directly into electricity using semiconductors. The advantages include sustainability, profit opportunities, and minimal pollution. However, the downsides consist of high costs, space requirements, and effectiveness limited to sunny regions. The future holds promise, with projections of solar energy contributing significantly to global consumption by 2050.

  1. Solar Energy By: Evan, Max, and Grant

  2. Definition • There are two types of ways to create power from the sun. The first is CSP, concentrated solar power, is when you concentrate a large amount of light (sun) To heat something (water) and create steam. The other one is photovoltaic (PV) to work this you need a semiconductor. When the sun hits it the electrons are knocked out of there atoms and into a circuit. • Info from www.wikipedia.com

  3. How it works • YouTube - solar energy This is how the photovoltaic (PV) type works • YouTube - Energy 101: Concentrating Solar Power This is how concentrated solar power (CSP) works.

  4. Advantages • The sun will never run out so we will always have solar energy. • People that have solar panels at their houses make money because the extra energy goes to their neighbors then the government sends them money • Solar energy does not pollute at all • you do not need to do a lot of work on the solar panels you can just leave them. • Info from http://www.solarhome.org/infoadvantagesofsolarenergy.html

  5. Disadvantages • Solar panels can be very expensive. • You need a large amount of space for the panels to be efficient. • The pollution and clouds block the rays that are coming to the solar panels. • It only works good in sunny states. • Info from http://www.clean-energy-ideas.com/articles/disadvantages_of_solar_energy.html

  6. Where? • PV is mostly used in California, New York, and New Jersey. • CSP is used mostly in California and Nevada. • Info from ehow.com • Picture from homemadediysolar.com

  7. Conclusion • We think that it is very efficient because the sun will never run out [other than at night). Also we can keep expanding our uses of it, from a lamp to a car or house. • It is not able to power all of our energy needs because you need to live in a sunny place year round. For example Michigan is not sunny for half of the year.

  8. Future • In 2050 the worlds energy will become 25% solar power, right now it runs on 0.5%. • Info from cnn.com

  9. BYE • Thanks for watching.
