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. Energy efficient smaller technology to be used in every day life






2. 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






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






4. Central retriever system that uses mirrors to collect heat






5. Corporate Average Fuel Economy






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






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






8. Collectors absorb energy and a fan or pump supplies part of the building's space heating






9. Mixture of steam and water droplets






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