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






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






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






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






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






6. Organic material that can be used as fuels






7. Energy from heat contained in underground rocks

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






20. Department of Energy






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






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






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






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

27. Central retriever system that uses mirrors to collect heat






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






29. Mixture of steam and water droplets






30. Ocean Thermal Energy Conversion






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






32. Low dam is built across a stream






33. Stores hydrogen above or below ground - very expensive






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






35. Steam with no water droplets






36. 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






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






38. Initial cost plus lifetime opperating cost






39. Central retriever system that uses mirrors to collect heat






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. Stores hydrogen above or below ground - very expensive






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