Exploring Energy

1. 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.
4. External surroundings
7. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
9. A propeller driven by the wind and connected to a generator. The wind makes it turn the generator, which produces electricity.
11. The use of flowing water from waterfalls and dams to produce electricity.
16. Energy from the sun.
17. An energy source that will never run out
19. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
22. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
23. Plant materials and animal waste used especially as a source of fuel.
25. A measure of power equal to one joule of work per second.
26. The power of the atom.
27. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
29. Energy derived from wind by means of windmills or wind turbines.
31. A resource that can be replaced when needed.
32. A unit measure of work.

2. A resource that cannot be replaced once used.
3. The flow of electrical power or charge.
5. The potential energy locked within a system and released during a chemical reaction.
6. Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines
8. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
10. A natural fuel such as coal or gas formed in the geological past from the remains of living organisms.
12. Energy in transit.
13. Gas usually found within the vicinity of petroleum reserves
14. The process of controlling resources; for example, limiting soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
15. The rate at which work is performed or energy is expended
18. Any source of energy that is limited and cannot be replaced when it is used, such as oil, coal, and natural gas.
20. Any significant change in measures of climate, such as temperature, precipitation, or wind, lasting for an extended period of a decade or longer.
21. Energy visible to the eye.
24. The energy possessed by a body as a result of its motion.
28. A result of a force moving an object a certain distance.
30. Energy stored in the earth in the form of heat.
