25 Questions

1. Microscopic dying organisms sink to the bottom of the ocean secreting drops of oil - shale is formed from mud and sediment with oil droplets - over time the droplets rise into a pocket in the ground

2. Solar energy heats water which turns a turbine

3. Solar radiation from the sun is converted to heat or electricity

4. Water floods - peat and sediment is pushed down - peat is pressed down for millions of years - coal is formed

5. Secondary Pollution -Toxic materials and alcohols -Blocking the sun for some animals -No direct pollution though! Bird death ray - Startup cost

6. Solar cells to convert solar energy directly to electricity

7. Volcanoes - hot springs - geysers

8. Unreliable - energy companies only see it as supplemental power - strong winds are usually not near people or grids

9. High tidal range - mouths of bays and estuaries - ideally near poles

10. Slow decay of radioactive particles in rocks gives off heat

11. Soft coal - reduced water (3%)

12. Radiant energy form the sun heats earth and atmosphere - causes warming of the air and wind cycle

13. Bacteria ferments biomass with sugars

14. Air heated more from ground near equator - creates global jet streams

15. Organic materials are changed to lighter - more volatile hydrocarbons

16. Lowest rank coal - less water and higher proportion of burnable materials than peat (40% water)

17. Burning rubbish/garbage

18. Same as pyrolysis process but with more heat and less gas - goes all the way to gas

19. Known deposits which can be extracted from profitably using modern technology under certain economic conditions

20. Off shore wind is the most efficient

21. 3 factors that affect volatility

22. Changes landscape - land reclamation - acid min drainage - black lung - foundation damage (subsidence) - mountain top removal - insurance - most danger

23. Secondary pollution (toxic materials and alcohols - blocking the sun for some animals) - bird death ray - startup cost

24. Difference between high and low tide

25. Wood - crops grown for energy - crop residues - animal waste - algae - some garbage
