Which resource is renewable?
A. Coal
B. Crude Oil
C. Whale Oil
D. Natural
D. Natural gas
I searched Google under the key words "renewable energy sources" to get these possible sources:
http://en.wikipedia.org/wiki/Renewable_energy
http://www.eia.doe.gov/kids/energyfacts/sources/renewable/renewable.html
http://www.teachers.ash.org.au/jmresources/energy/renewable.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. Thanks for asking.
