Across
  1. 3. A collection of wind turbines used to create electricity.
  2. 6. Plant materials and animal waste used especially as a source of fuel.
  3. 9. The heat equal to 1/180 of the heat required to raise the temperature of one pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit at a constant pressure of one atmosphere.
  4. 12. The power of the atom.
  5. 13. Oil.
  6. 15. Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
  7. 20. The potential energy locked within a system and released during a chemical reaction.
  8. 22. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
  9. 23. External surroundings.
  10. 24. Energy from the sun.
  11. 26. Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
  12. 28. A result of a force moving an object a certain distance.
  13. 29. Energy visible to the eye.
  14. 31. A device that converts light into electricity.
  15. 32. A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
  16. 33. Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
  17. 34. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
  18. 35. Energy can be neither created nor destroyed. There is a fixed amount of energy present in different forms that can be converted from one form to another, but energy does not go away.
  19. 38. The phenomenon whereby the earth's atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.
  20. 39. The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
Down
  1. 1. Gas usually found within the vicinity of petroleum reserves.
  2. 2. A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
  3. 4. Energy derived from wind by means of windmills or wind turbines.
  4. 5. A measure of power equal to one joule of work per second.
  5. 7. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
  6. 8. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.
  7. 10. The energy possessed by a body as a result of its motion.
  8. 11. The flow of electrical power or charge.
  9. 13. A system by which electrical power is delivered throughout a region.
  10. 14. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
  11. 16. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
  12. 17. An energy source that will never run out.
  13. 18. The use of flowing water from waterfalls and dams to produce electricity.
  14. 19. A unit measure of work.
  15. 21. A resource that cannot be replaced once used.
  16. 25. Energy associated with the flow of electrons.
  17. 27. Energy stored in the earth in the form of heat.
  18. 30. A resource that can be replaced when needed.
  19. 36. The rate at which work is performed or energy is expended.
  20. 37. Energy in transit.
