Target: Describe each type of fossil fuel. Explain how it forms, is removed, and is processed. Discuss where it is found and the supply of the fossil fuel.

 99% solar energy  Indirect forms of renewable solar energy such as wind, falling and flowing water, and biomass  1% commercial energy sold in the marketplace  Nonrenewable mineral resources such as oil, natural gas, and coal

 78% fossil fuels (33% oil, 23% coal, 22% natural gas)  6% nuclear  10% biomass  5% hydropower  1% geothermal, wind, and solar nonrenewable renewable In developing countries, half of the people use biomass.

 Net energy: the usable amount of high-quality energy available from a given quantity of a resource.  Net energy = total energy available from the resource over its lifetime – amount of energy used, automatically wasted, and unnecessarily wasted.  Figure 17-7
