Fossil Fuels

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.

how is the earth heated
How is the earth heated?
  • 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
what is the world s current consumption
What is the world’s current consumption?
  • 78% fossil fuels (33% oil, 23% coal, 22% natural gas)
  • 6% nuclear
  • 10% biomass
  • 5% hydropower
  • 1% geothermal, wind, and solar

what is net energy and how do you determine it
What is net energy and how do you determine it?
  • 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.
