• renewable energy
  • solar energy
    • producing method
      • modern technologies can be adopted in capturing energy from the sun to producehot water steam or electricity.
    • service condition
      • provide power to watches and calculators
      • generate electricity to supplement localconsumption in a building or a designated
      • fed to the city electrical grid
      • solar hot water heaters produce hot water
      • materials that absorb and store the sun'sheat can be built into the walls release heatat night
  • wind power
    • service condition
      • milling grain
      • pumbing water
      • driving other mechanical devices
      • mass productin of electricity
    • located
      • on land
      • near-shore
      • off shore
    • used in many countries
      • Germany
      • Denmark
      • Spain
      • United states

      • landfill gas utilization
    • effect
      • producting greenhouse gases
  • others froms of renewable energy tochnology
    • species
      • hydroe lectric power
      • wave power
      • geothermal energy
      • energy from vegetation
    • solution
      • dictated by geographical conditions
        • has a wide variation among different countries
• Why use renewable energy
  • reason
    • to protect the environment
    • the increasing global energy demand will propel a more rapid depletion of the worid's fossill fuel reserves
  • advantage
    • reduce the reliance on exhaustible sources of fossil fuels
    • future worid with perfectly clean energy supply and water vapor as the only emission during the whole process
• Fossil fuel
  • The major energy source in our dally life
  • Example
    • Coal
    • Oil
    • Natural gas
  • Impact
    • Global warming
      • Affecting the agricultural production,andcausing rise in sea level
    • Atmospheric pollutants production
      • SO2
      • NOx
        • Affect human health,with particularadverse effects on the young children the aged,as well as people with chronichealth problems
      • RSPs
    • Economic development hindrance
      • Affect the activities of all walks of life andimpede economic development,result in the global degradation of people's livingstandard
