Across
  1. 6. generates little electricity but takes up little land space
  2. 8. uses kinetic energy of water to spin turbines, accessible energy
  3. 11. while it is renewable, it still releases co2 in the air when combusted (modern carbon)
  4. 12. sediments build up behind dam
  5. 13. can be easily accessible through geysers, hot springs, and volcanic land
  6. 14. easily accessible energy source, sunlight found everywhere
  7. 15. no greenhouse gas emissions, uses water
  8. 17. deforestation in developing nations
  9. 18. light beams from this could burn birds mid-air
Down
  1. 1. can only be used during the day (intermittency)
  2. 2. generates lots of electricity but takes up land space
  3. 3. may be unavailable in warmer seasons when river water levels are low
  4. 4. releases no air pollutants, only h20 vapor
  5. 5. materials like silicon need to be produced for these, also known as pv cells
  6. 7. uses the wind to spin turbines, easy and available access
  7. 9. costs of drilling into the ground for it costs a lot
  8. 10. releases particulate matter and respiratory irritants
  9. 12. can affect flying animals like birds and bats
  10. 14. energy no air pollutants (uses sun)
  11. 16. prevents upstream migration of salmon
