Energy Resources

• ✅ Fossil fuels (advantages)

  • widely available
  • cheap in cost of production
  • easy to transport
• ❌ Fossil fuels (disadvantages)

  • Pollution from gases
  • contributes to global warming
  • non renewable
• Fossil fuels (examples)

  • Petroleum ⛽️
  • natural gas 💨
  • coal 🪨
  • wood 🪵
• ✅ Biofuels (advantages)

  • Widely available
  • cheaper in cost of production
  • renewable
• ❌ Biofuels (disadvantages)

  • environmental pollution
  • contributes to global warming
• Biofuels (examples)

  • ethanol 🥃
  • biodiesel 🧪
  • biogas 💨
• ✅ Hydropower (advantages)

  • clean method and cheap
  • renewable (water movement can regenerate)
• ❌ Hydropower (disadvantages)

  • can cause flooding
  • high cost (dams, turbines, generators)
  • may cause environmental damage for surrounding rivers
• Hydropower (examples)

  • ocean waves 🌊
  • tides 🏝️
  • hydroelectric dam water 💦
• ✅ Geothermal resources (advantages)

  • clean source of thermal energy
  • renewable
• ❌ Geothermal resources (disadvantages)

  • pollution by poisonous gases (hydrogen sulphide)
  • not widely available
• Geothermal resources (examples)

  • hotspot: volcanic regions🌋
• ✅ Solar power (advantages)

  • no greenhouse gases
  • less polluting than fossil fuels
  • renewable
• ❌ Solar power (disadvantages)

  • expensive to install (solar cells)
  • weather-dependant (no sunlight at night)
  • uses up a lot of space
• Solar power (examples)

  • source for wind power 🍃
  • source for hydropower 🌊
• ✅ Nuclear power (advantages)

  • reduces greenhouse gas emissions
  • higher reliability
• ❌ Nuclear power (disadvantages)

  • risks when there’s improper disposal of radioactive waste
  • non renewable (nuclear fuel is limited)
• Nuclear power - fission vs fusion

  Fission: the splitting of atoms to produce energy

  Fusion: the joining of atoms (e.g. hydrogen atoms fuse to form helium)
