Which are non-renewable energy sources? solar energy fossil fuels hydro-energy nuclear energy

I just turned in my assignment and the answers are:

"Fossil Fuels"

"Nuclear Energy"

The following is a section from my lesson:

Energy can be derived from both renewable and nonrenewable sources. A nonrenewable resource is one that cannot be replenished (made again) in a short period of time. All fossil fuels, such as natural gas, oil, and coal, are nonrenewable. On the other hand, many of the renewable fuels used in the past are gaining new popularity today. Renewable sources of energy, such as solar energy, can be readily replenished (Alpha Omega Academy, Semester 2, Unit 1 --> "Work and Energy", Lesson 1 --> "Forms of Energy").

Hope this helps! :)
