Study Notes

  • Hornsea One, the world's largest offshore wind farm, completed construction last year in the North Sea.
  • 174 wind turbines, each 190 meters tall, occupy over 400 sq km of the North Sea, 120 km off the east coast of England.
  • Hornsea One generates enough electricity to power one million UK homes
  • Hornsea Two, an equally large wind farm adjacent to Hornsea One, is expected to become operational this year.
  • Additional plans to construct wind farms Hornsea Three and Four are in progress
  • The UK has over 11,000 wind turbines, making it a world leader in wind energy
  • Wind power accounts for approximately 25% of the UK's electricity production
  • In the Republic of Ireland, over 300 wind farms generate over a third of the country's electrical power.
  • 2021 saw record levels of green energy production worldwide.
  • The expansion of electricity generated from renewable sources like wind and solar is expected to accelerate.
  • Green technologies are becoming more affordable and competitive.
  • Renewable energy is an effective measure against global warming.
  • Following COP 26 in Glasgow last year, many governments committed to investing in green energy.
  • Renewables contribute to economic development
  • Approximately 12 million people are currently employed in the green energy sector
  • It's predicted that 100 million people will be employed in green energy by 2050.
  • Wind turbines are attracting tourists.
  • Wind farms near Palm Springs, California, charge $35 for tours.
  • Rhode Island offers 1-hour ferry tours of an offshore wind farm.
  • Some solar farms now grow crops beneath solar panels, using land for both food and electricity production.
  • Technology is being used to restore natural habitats.
  • Flash Forest, a Canadian company, uses drones to plant trees.
  • Drones map optimal planting areas and then shoot seed-containing pods into the ground.
  • The Flash Forest process is faster and cheaper than traditional tree planting.
  • Apps like Wren help calculate carbon footprints and suggest actions for becoming more 'green'.
  • Ecological alternatives exist for many everyday activities, including eating, travel, shopping, and entertainment.
  • Ecosia, a search engine, dedicates the majority of its profits to reforestation, planting a tree for every 45 web searches.
