What is the difference between renewable and nonrenewable energy sources

nonrenewable resources are materials or energy sources that cannot be replenished once used and renewable sources are regenerated

why does the US get over 80% of its energy from non-renewable resources

Because they are cheaper and more accessible

Water flowing over dams

what is a nonrenewable energy source?

Materials or energy sources that cannot be replenished once used, they form very slowly by natural processes and will not form ever again in the course of human lifetimes

What is renewable energy source

Can be regenerated in our lifetime however, they can still be damaged, polluted, or overused

Why is soil considered a non-renewable resource?
