Across
  1. 2. hydrogen atoms powers the sun and stars by.....
  2. 4. the solar energy that is absorbing or blocking heat from the sun, without use of mechanical equipment
  3. 7. formed primarily from the remains of decayed swamp plants
  4. 10. the nuclear accident caused by a tsunami in Japan
  5. 12. energy from moving water
  6. 14. coal, natural gas, and oil are examples of this energy
  7. 16. Nuclear meltdown that took place in Ukraine
  8. 18. leftover rock and soil from mining tht may have radioactive elements that can contaminate water or soil

  10. 24. Nuclear meltdown that took place in Pennsylvania, United States
  11. 25. organic matter such as wood, algae, charcoal, burned to release heat
  12. 26. the amount of time it takes for 50% of a radioactive substance to decay (breakdown)
Down
  1. 1. aka "solar panels"
  2. 3. is an environmental impact from burning coal, releasing sulfuric acid into the atmosphere
  3. 5. an alternative that enables salmon to be captured or directed into a tube that carries them over the dam
  4. 6. how we extract natural gas
  5. 8. what we mind to fuel nuclear power
  6. 9. restoring the native plants and wildlife to the area
  7. 11. the solar energy that uses mechanical equipment
  8. 13. how we extract coal
  9. 15. the power that radiation is involved with
  10. 17. liquid fuels (ethanol, biodiesel) created from biomass (corn, sugar cane)
  11. 19. energy source/heat that comes from within the Earth
  12. 21. uranium atoms power plants by .....
  13. 22. used ones of these remain radioactive for millions of years and need to be stored in lead containers onsite
  14. 23. wind, water, and solar are examples of this energy
