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. Organic material that can be used as fuels






2. Energy from heat contained in underground rocks






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






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

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






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






43. Collect and transform radiant energy from the sun into thermal energy that can be converted to electricity






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






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






46. Stores hydrogen above or below ground - very expensive






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






48. Steam with no water droplets






49. 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






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