Transcript of Aitana Renewable and non renewable sources

  • Renewable and non-renewable energyAITANA MONTOLIU CANO 6C

  • Renewable energyRenewable enrgy is energy which is generated from natural sources.They are available in plenty and by far most the cleanest sources of energy available on this planet.

    For example:

  • EXAMPLESSOLAR ENERGYWIND POWERHYDRAULIC ENERGYBIOMASS

  • SOLAR ENERGYSolar energyis radiantlightandheatfrom thesunharnessed using a range of ever-evolving technologies such assolar heating,solar photovoltaics,solar thermal energy,solar architectureandartificial photosynthesis.

  • WIND POWERWind poweris extracted fromair flowusingwind turbinesorsailsto produce mechanical orelectrical power.

  • HYDRAULIC ENERGYHydraulic energy ispowerderived from theenergyof falling water and running water, which may be harnessed for useful purposes.

  • BIOMASSBiomassisbiological materialderived from living, or recently living organisms.

  • Non-renewable energyNon-renewable energy is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames.

    For example:

  • EXAMPLESCOALPETROLEUMNATURAL GAS

  • COALCoal is acombustibleblack or brownish-blacksedimentary rockusually occurring inrock stratain layers or veins calledcoal bedsorcoal seams.

  • PETROLEUMPetroleum is a naturally occurring, yellow-to-blackliquidfound ingeological formationsbeneath theEarth's surface, which is commonly refined into various types offuels.

  • NATURAL GASNatural gasis afossil fuelformed when layers of buried plants, gases, and animals are exposed to intense heat and pressure over thousands of years.
