Answer to Question 1

Answer: No, it's not. The rocks at the bottom of the Grand Canyon are igneous and metamorphic, and they are also really, really old. Carbon-14's usefulness is limited to living things (which consume carbon-14 every time they photosynthesize or eat) from the relatively recent past (because carbon-14 has such a short half-life, it decays very quickly over geologic time).

Answer to Question 2

Answers should include coal, oil, nuclear, hydroelectric, and imported sources.
