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