Across
- 1. layer blocking heat from escaping
- 3. to obtain biomass energy in any form starts with a c
- 4. using percentage of energy that is only to perform work
- 7. part of nuclear where fission occurs
- 8. way to obtain biomass using yeast resulting in ethanol
- 9. when burned chemicals are released
- 13. putting 2 hydrogen nuclei together
- 15. gasoline mixed with alcohol, is a biomass
- 16. means world heat in its root word
- 18. a fossil fuel that begins with a c
- 20. splitting apart the molecules (nuclear fission) in water that creates hydrogen and oxygen
- 21. Ways to obtain biomass fuel (mostly wood)
- 24. renewable, pushes against turbine to create this and could be on top of tower
