Global energy consumption by source
Global Energy Consumption by Source

  • What is the total percentage for fossil fuels?

    • 80%

  • What is the total percentage for nuclear?


Fossil fuels
Fossil fuels

  • Oil (crude oil, petroleum)

  • Coal

  • Natural Gas

  •  all formed millions to hundreds of millions of years ago

    • Carboniferous age (360-280 million years ago)

  • ``cooking’’ of dead organic matter


How do we generate electricity from these fuel sources
How do we generate electricity from these fuel sources?

  • -A fancy way of boiling water

  • Heat is generated by burning of fossil fuels or nuclear reaction

  • Heat causes water to boil which generates steam

  • Steam causes a turbine to spin which generates electricity

Coal

-World coal production in 2010

Non renewable energy resources
Coal

  • How does coal form?

    • Forms from dead and decaying organic material (plants) in swampy areas

    • As it gets buried, temperature and pressure “cook” it



Non renewable energy resources
Coal

  • Shaft mining

    • Less environmental impact than open pit

    • More dangerous


Non renewable energy resources
Coal

  • Open pit coal mine

    • Very large! Some can be seen from

      space

Coal

More impacts on the environment

Less dangerous than shaft mining


Non renewable energy resources
Coal

  • Burning coal produces air pollution

  • All coal burning produces sulfur which can cause acid rain

  • In China there are “blue sky” ratings based on the days Air Quality Index (AQI) as a result of air pollution


Natural gas
Natural Gas

  • Mainly methane: CH4

  • Does methane smell?

    • No. The gas that is piped into your home for heating or cooking has a smell added to it so you can detect a leak or malfunctioning appliance.

  • Burns relatively cleanly

Natural Gas

  • Electric power is the largest use of natural gas

  • Residential use includes home heating and cooking


Non renewable energy resources

State-of-the-art landfill

Captures methane


Natural gas and oil formation

In seas

Small organisms—plants and animals—settled out in the mud at the bottom

Buried under more silt, mud

Cooked under heat and pressure

Oil eventually moved into permeable rock—reservoirs—where oil is found today

Tiny plants and animals

Exxon Valdez aground on a reef, Prince William Sound, Alaska

-March 1989

11 million gallons of oil were spilled

(roughly equal to 17 Olympic size swimming pools)

Oil

  • Deep ocean oil drilling is more difficult and more expensive than drilling on land


Non renewable energy resources

The Deepwater Horizon offshore oil platform caught fire and sank with the loss of 11 crew members, as the well was being closed pending later production.

April 20, 2010
