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. Mixture of steam and water droplets






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






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






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






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






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






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






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






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