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. Distributed reciever system with sunlight collected and focused on pipes






2. Stores hydrogen above or below ground - very expensive






3. Corporate Average Fuel Economy






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






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






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






7. Steam with no water droplets






8. 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

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






22. Central retriever system that uses mirrors to collect heat






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






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






25. Use bowls basically to store sunlight






26. Use bowls basically to store sunlight
