Energy Efficiency And Renewable Energy Revolution

Subject : science
Instructions:
  • Answer 50 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. The percentage of total input into a conversion device or system that does useful work and is not converted to useless heat






2. Absorbs and stores heat from the sun directly within a structure. Example is greenhouse






3. Absorbs and stores heat from the sun directly within a structure. Example is greenhouse






4. Stores hydrogen above or below ground - very expensive

9. Produces hydrogen by using chemical processes and high temperatures to seperate hydrogen atoms from carbon






10. Low dam is built across a stream






11. Distributed reciever system with sunlight collected and focused on pipes






12. Energy of the entire delivery process - determined by efficiency of each step of the procedure






13. Combined heat and power CHP - two useful materials are produced from the same fuel source.






14. Stores hydrogen above or below ground - very expensive

37. Department of Energy






38. Energy efficient smaller technology to be used in every day life






39. Energy from heat contained in underground rocks






40. Where hydrogen and oxygen are combined to produce electrical currents - have no moving parts - are quiet - only emit water or heat - and are more reliable






41. Organic material that can be used as fuels
