One of Florida's non-renewable resources is limestone. The time it takes Florida's limestone to regenerate far surpasses the amount of time that it can be used-- thus limestone is categorized as a non-renewable resource.
Biomass is a non-renewable resource because once the process of converting livestock to emit 19,000 tons of methane that could generate clean electricity is used once, it cannot be replaced.
Both oil and gas are non-renewable, because it takes them an extensive period of time to reform.
