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. Started at the end of the Age of Oil






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






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






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






6. Ocean Thermal Energy Conversion






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






8. Department of Energy






9. Central retriever system that uses mirrors to collect heat






10. Energy from heat contained in underground rocks






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

22. Organic material that can be used as fuels






23. Homes with walls made of bales covered with plaster or adobe






24. Mixture of steam and water droplets






25. 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






26. Use of passive solar energy and solar cells






27. Initial cost plus lifetime opperating cost






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






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






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






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






32. Mixture of steam and water droplets






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






34. Ocean Thermal Energy Conversion






35. Use bowls basically to store sunlight






36. Low dam is built across a stream






37. 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






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






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






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






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