Nonrenewable Energy Resources The higher the concentration of carbon in coal is, the cleaner it burns. Oil and natural gas form from altered and buried marine organisms and often are found near one another. Nuclear energy is obtained from the fission of heavy isotopes.

To return to the chapter summary click Escape or close this document. 2 2 Reviewing Main Ideas Inexhaustible energy resources—solar energy, wind energy, hydroelectric energy, and geothermal energy—are constant and will not run out. Renewable Energy Resources Renewable energy resources are replaced within a relatively short period of time. Biomass energy is derived from organic material such as wood and corn.
