  • reducing carbon emissions
    • limit burning of fossil fuels
    • burns biofuels instead
    • use renewable energy sources
  • biofuels
    • recently living plant biomass
    • release C02 when burnt
  • advantages of biofuels
    • cheaper than oil
    • carbon neutral-release carbon which was recently removed from atmosphere when plant was alive
    • renewable resource- regrown quickly
  • disadvantages of biofuels
    • amount of land used to grow plants could be used for food production
    • creating land for biofuel growth involves loss of habitats- decreasing biodiversity
    • cutting down mature trees to create land for biofuel growth, decreases removal of C02 via photosynthesis
  • renewable energy sources
    • no C02 released
    geothermal- only used when volcanic activity close to earths surface
    solar- depends on sunshine hours
    wind-wind speeds and visual impacts of wind turbines
    tidal-only generated near coast
