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. Energy from heat contained in underground rocks






2. Ocean Thermal Energy Conversion






3. Collectors absorb energy and a fan or pump supplies part of the building's space heating






4. Stores hydrogen above or below ground - very expensive






5. Photovoltaic cells - or solar cells. Transparent wafer with a semiconductor material hanging and creates an electrical current






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






7. Use bowls basically to store sunlight






8. Use bowls basically to store sunlight






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






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






11. Central retriever system that uses mirrors to collect heat






12. Stores hydrogen above or below ground - very expensive






13. Initial cost plus lifetime opperating cost






14. The percentage of total input into a conversion device or system that does useful work and is not converted to useless heat

33. Started at the end of the Age of Oil






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






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






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






37. Pumps using surplus electricity from a powerplant pump water from one lake to another






38. Organic material that can be used as fuels






39. Central retriever system that uses mirrors to collect heat






40. Dam is built across a large river to create a resevoir - uses turbines
