  • Physics: 1b
    • Fossil fuels
      • are non- renewable
      • most power stations use fossil fuels to produce electricity
      • release CO2 when burned
        • adds to the greenhouse effect and encourages global warming
      • can release sulfur dioxide when burned
        • causes acid rain
      • give off a lot of energy
    • Wind power
      • wind turbines put up in exposed areas
        • electricity produced directly form the wind
      • no pollutants
      • noisy
      • doesn't produce enough energy as fossil fuels
      • relies on windy weather
    • Wave power
      • kinetic energy from waves drives electrical generators
      • renewable
      • no fuel costs
      • no waste
      • not reliable- depends on weather
