Sustainable Energy

Subject : engineering
Instructions:
  • Answer 21 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Process of splitting water into hydrogen and oxygen by means of an electric current.






2. Substances discharged into the air (as by a smokestack or an automobile engine)






3. A field of electromagnetic energy produced by electricity flowing through power lines.






4. Moves energy in a usable form from one place to another - like electricity or hydrogen.






5. Any unit that converts some form of energy into electrical energy - such as a hydroelectric or steam- generating station - a diesel- electric engine in a vehicle - or a nuclear power plant.






6. A device used to increase or decrease voltage supplied to a circuit.






7. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air.






8. A negatively charged particle.






9. Process in which high- temperature steam separates hydrogen from carbon atoms in methane (CH4).






10. A solar energy collection system that uses electrical or mechanical components to heat water or heat and cool buildings or produce electricity.






11. The first and simplest element on the periodic table. It is one of the most common elements in the galaxy.






12. Device that combines hydrogen - or other fuels - and oxygen and produces electricity in the process.






13. A system of high- tension cables by which electrical power is distributed throughout a region.






14. An electrical power distribution network that can transmit electricity - including two- way - digital communications between producers and consumers. A smart grid includes an intelligent monitoring system that keeps track of all electricity flowing i






15. Conserving resources through efficient and prudent use.






16. A solar energy collection system that does not require electrical or mechanical components; can directly heat water or buildings or reduce solar heat gain or provide lighting.






17. Naturally occurring materials found within the Earth or its atmosphere.






18. Fuels to eventually replace dwindling supplies of fossil fuels - such as biodiesel and hydrogen.






19. A device used to convert mechanical energy into electrical energy.






20. Engineering that focuses on the development of a sustainable future through renewable energy - wise use of natural resources - recycling - and assessment of environmental impact.






21. A direct current voltage source made up of one or more units that convert chemical - thermal - nuclear - or solar energy into electrical energy that can be stored until it is needed.
