- 7. Gas Gas usually found within the vicinity of petroleum reserves.
- 8. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it.
- 10. Energy The energy that a piece of matter has because of its position or nature or because of the arrangement of parts.
- 11. Grid A system by which electrical power is delivered throughout a region.
- 12. The ability to do work; types include heat, light, sound, chemical, nuclear, mechanical, electrical.
- 15. Cell A device that converts light into electricity.

Down
- 1. Effect 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.
- 3. Energy The energy possessed by a body as a result of its motion.
- 6. External surroundings.
- 9. Oil.
- 13. Energy The use of flowing water from waterfalls and dams to produce electricity.
- 14. Refers to the use of resources in ways that prevent their being depleted or permanently damaged.
- 16. Controlling Resources for example conserving water in a reservoir.
- 17. Energy Energy produced by mechanical devices, such as gears, pulleys, levers, or internal combustion engines.
- 19. of Conservation of Energy 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.
- 22. A result of a force moving an object a certain distance.
