Across
- 4. electricity produced from the generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
- 8. the movement of heat through matter, from an area of high heat and low heat
- 13. a dynamo or similar machine for converting mechanical energy into electricity
- 14. energy stored in plants material can be used to generate heat, electricity and ethanol fuel used in cars
- 17. sources of energy that are used up much faster than they are renewed naturally in the environment
- 19. the practice of decreasing the amount of energy that it used
- 20. heat from the earth mantle is used to generate steam, which turns a generator to produce electricity
- 22. the flow of electrically charged particles in a conductor
- 23. a vector field that describes the magnetic influence of electric charges in relative motion and magnetic material
Down
- 1. an electric lamp that produces light through fluorescence
- 2. a type of vehicle that combines a conventional internal combustion engine system with an electric propulsion system
- 3. energy which is stored and available for use
- 5. energy that can replenish itself as long as we use it sustainably
- 6. the movement of water through air and water
- 7. radiant energy emitted by the sun
- 9. energy which is in motion
- 10. wind turning the blades which then turns to a generator
- 11. a material that resists the flow of heat through it
- 12. energy created with the help of turbines
- 15. a device converting solar radiation into electricity
- 16. material that allows heat to pass through it
- 18. the level in which energy is wasted or not wasted
- 21. movement of energy in wave for
