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. Stores hydrogen above or below ground - very expensive






2. Steam with no water droplets






3. Low dam is built across a stream






4. Department of Energy






5. 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






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






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






8. Department of Energy






9. Initial cost plus lifetime opperating cost






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






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






12. Organic material that can be used as fuels






13. Central retriever system that uses mirrors to collect heat






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