Solar power

  1. 1. Solar Power By: William Jeong Mrs. Schmidt Physical Geography
  2. 2. What is Solar Power? <ul><li>Solar Power – Conversion of sunlight into energy (electricity) </li></ul>
  3. 3. Solar thermal energy <ul><li>Panels reflect sunlight into a tower </li></ul><ul><li>The sunlight is converted to heat which boils the water. </li></ul><ul><li>Steam turns the turbines to generate electricity. </li></ul>
  4. 4. Where is our Solar Power? <ul><li>Harvesting solar power is generally seen in 1 st world countries and in areas where sunlight is abundant. </li></ul><ul><li>Generally more popular in suburban homes. </li></ul><ul><li>Solar power plants are slowly growing but coal and nuclear power plants are favorable due to its cheap price. </li></ul>
  5. 5. How does it affect life on Earth? <ul><li>It affects life on Earth because it is a clean and renewable energy. </li></ul><ul><li>The sun produces more energy every hour than the entire energy needs of human civilization from the beginning of time. </li></ul>
  6. 6. Why are we hesitant to use Solar power? <ul><li>Competition is minimal (Solar power companies have monopolies, very expensive to install) </li></ul><ul><li>Government regulations will not allow house owners to install their own systems </li></ul><ul><li>Solar power is profitable only in high sunlight regions </li></ul><ul><li>Builders find that it is not profitable for them to spend excessive architectural fees on designs that are not mainstream and salable </li></ul><ul><li>It is inefficient. Solar panels can only convert 15% of the Sun’s energy. </li></ul><ul><li>In other words, it costs too much . </li></ul>
  7. 7. How can we solve this? <ul><li>The most natural solution is time. </li></ul><ul><li>With advancing technology, installing and creating solar panels and factories will become cheaper and more efficient. Currently, solar panels can only convert 15% of the Sun's energy </li></ul><ul><li>As non-renewable energy, such as coal, becomes more scarce, there will be a greater demand for renewable resources. </li></ul><ul><li>It costs 5 times more to generate electricity from solar panels than from cheap dirty coals. </li></ul>
  8. 8. Statistics on electricity generation   US 1 Canada 2 Coal 48.5% 24.9% Natural Gas 21.6% 3.8% Nuclear 19.4% 12.4% Hydro 6.0% 58.7% Petroleum 1.6% - Wood 0.94% - Wind 0.83% - Biomass 0.40% - Geothermal 0.35% - Other Gases 0.32% - Solar 0.01% -
