• What are tidal barriers used for?


  To help reduce flooding
• How can tidal barriers impact wildlife?


  They can increase wildlife
• What type of areas are suitable for tidal barriers?


  Only a few estuaries
• What is a limitation of geothermal energy?


  It is expensive to set up and only works in areas of volcanic activity
• What is a potential drawback of geothermal energy?


  It requires volcanic activity
• What is one characteristic of solar energy?


  It cannot be used at night
• How can individuals utilize solar energy?


  They can have their own energy systems
• What are some examples of renewable energy sources?


  Wind, solar, and geothermal
• What is a disadvantage of using fossil fuels?


  They release greenhouse gases when burned
• What is a trend in global energy use?


  Energy use is increasing
• What is the expected percentage of renewable energy in total energy consumption by 2035?


  It is unlikely to change from around 20%
• How does the increase in population affect energy consumption?


  Each person is using more energy
• What are the main energy sources and their characteristics?

  • Tidal barriers: Reduce flooding, increase wildlife, suitable in few estuaries
  • Geothermal: Expensive, works in volcanic areas
  • Solar: Cannot be used at night, can be individually harnessed
  • Fossil fuels: Release greenhouse gases, non-renewable
  • Renewable energy: Includes wind, solar, geothermal, expected to be 20% of total energy by 2035
• What is the impact of renewable energy on future energy supplies?


  The use of renewables will increase as fossil fuel supplies decline
• What is the relationship between energy use trends and population growth?


  Energy use trends increase as the population grows
• How does the availability of renewable energy sources compare to fossil fuels?


  Renewable sources are becoming more prevalent as fossil fuel supplies diminish
