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. Started at the end of the Age of Oil






2. Central retriever system that uses mirrors to collect heat






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






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






5. Low dam is built across a stream






6. Low dam is built across a stream






7. Ocean Thermal Energy Conversion






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

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






23. Steam with no water droplets






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






25. Stores hydrogen above or below ground - very expensive






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






27. Organic material that can be used as fuels






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