Answer:
1). Renewable energy resources include: solar, wind, water (hydro), biomass, and
2). Nonrenewable energy resources include: coal, nuclear, oil, and natural gas.
Explanation:
Renewable energy resources are replenished naturally and over relatively short periods of time while Nonrenewable energy resources as their name applies are limited in their quantity and supplies too.
These forms of energy are primary formed when fossil fuels are destroyed by use, i.e they are not been recovered(nonrenewables); which brings in alternative sources(renewables).
Human supplies of fossil fuels and minerals are dwindled fast. These are nonrenewable resources as we cannot produce them by any process. Our demand for these limited resources, however, is constantly increasing. So we to cut down their wastages, find acceptable alternatives and also recycle them where possible.
