Fossil fuels (coal, oil, and natural gas) and nuclear energy are all forms of

• renewable energy sources
• nonrenewable energy sources
• nonpolluting energy resources
• measurements of density

Hydropower and hydroelectric are other terms used to in place of 

• water energy
• solar energy
• wind energy
• biomass energy

Coal, oil, and natural gas are all forms of

• renewable energy
• fossil fuels
• unlimited resources
• clean energy resources

All fossil fuels originally obtained their energy from 

• plants
• animals
• the Sun
• special nutrients in the soil

Renewable resources are 

• considered inexhaustible resources
• limited in supply
• fossil fuels and nuclear power
• used faster than they are replaced by natural processes.

Nonrenewable resources 

• have a limited supply
• have unlimited supplies
• don't cause any pollution
• include wind, solar, biomass, and geothermal energy.
