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






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






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