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. 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






2. Conserving resources through efficient and prudent use.






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






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






5. Process of splitting water into hydrogen and oxygen by means of an electric current.






6. A negatively charged particle.






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






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






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






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






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






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






13. 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.






14. 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.






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






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






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






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






20. 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.






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