### fuel:

Fossil fuel
* All fossil fuels contain carbon
  - produce air pollution to some extent, even natural gas, which is the cleanest
* Any fossil fuel releases heat and chemical energy after combustion.
* Are carbon-based fuels, formed from remains of living matter.
* Every fossil fuel gives off carbon monoxide when it burns.
* Most fossil fuel affects environments
  - comes from materials
  - consists of carbon
* Most fossil fuel contains compounds
  - sulfur compounds
  - creates gases
  - is used by humans
* Most fossil fuel produces electricity
  - heat energy
  - provides energy
* Most fossil fuel provides high energy
  - quality energy
* Most fossil fuel releases carbon dioxide
  - sulphur dioxide
* Some fossil fuel contains energy
  - much energy
  - includes coal
* accounts for all power production.
* are a byproduct of solar energy
  - finite resource
  - leading source of air and water pollution
  - limited resource as well
  - limited, nonrenewable resource
  - major contributor to air pollution in the form of smog and acid deposition
  - short-term, finite resource
  - valuable source of energy
  - all hydrocarbons formed from decaying organic matter under severe pressure
  - among the most commonly used forms of energy in the world
  - at the core of the current climate crisis
  - burned to generate much of our electricity
  - by far the leading source of energy for the world currently
  - coal , oil , and natural gas
  - coal, oil and natural gases
  - concentrations of peat, coal, oil, and natural gas
  - considered minerals
  - crude oil, natural gas, and coal
  - energy sources that are naturally found in the earth's crust
  - essentially the same thing, just old
  - fast depleting, name some future fuels
  - finite resources, and are being exhausted at an unsustainable rate
* are formed by natural processes such anaerobic respiration of buried dead organisms
  - under the ground
* are fuels excavated from the earth, such as petroleum, natural gas, or coal
  - such as coal, oil, and natural gas
  - just one of countless sources of energy
  - largely carbon, which burns to carbon dioxide
  - less expensive than other types of energy and are easy to be found
* are made up mainly of carbon
  - of plant and animal matter
  - non renewable resources
  - one finite resource that has created much turmoil in our world
* are one-time energy gifts to the human race
  - rock-like, gas, or liquid resources that are burned to generate power
* are the basis of modern urban civilization
  - chief source of the pollutants that are disrupting the earth's climate
  - fossilized remains of prehistoric animals and plants
  - greatest contributors to air pollution and acid rain
  - key to the high-productivity agriculture upon which American consumers rely
  - leading non-renewable energy sources around the world
  - to the world economy what blood is to the human body
  - used in the shipping and transport of the product and materials
* can have significant damaging impacts locally, regionally and globally.
* cause pollution, heating the atmosphere and water systems.
* come in three major forms coal, oil and natural gas.
  - the earth and was produced by a natural process
* consist of decomposed plant and animal matter.
* contain carbon from the earth surface at one point as well
  - stored solar energy and are considered nonrenewable resources
* create pollution and global warming.
* drive the digital age.
* give off tremendous amounts of water vapor.
* harm biodiversity in two other ways.
* have a limit as to how much is available
  - powerful attractions to cold naked apes who have cut down too many trees
* is also environmentally costly
  - an energy source that is used widely in the world
  - another term for nonrenewable energy sources
  - inanimate objects
  - mostly carbon, created in a carbon cycle that closed millions of years ago
  - the result of plants storing energy after photosynthesis
* produce a lot of pollution when burned
  - greenhouse gases that many scientists believe are making the planet warmer
* provide most of the energy that powers U.S. industry
  - ninety five percent of the energy consumed
* remain the dominant fuel.
* remove carbon that is stored underground and transfer it to the atmosphere.
* represent carbon storage areas
  - natural capital
* supplies energy.
* take millions of years to form, and minutes to consume
  - make but burn and disappear in seconds
  - produce in the ground
+ Fossil fuel, Problems: Geology :: Fuel
  * Fossil fuels produce a lot of pollution when burned. This pollution is responsible for causing the earth to get warmer, called global warming. They are also non-renewable resources, there is only a limited amount of coal, gas, and oil, and it is not possible to make more. Eventually all the fossil fuels will be used. Scientists think that coal will have run out by 2230 and oil by 2030. Scientists are looking at ways of using renewable energy sources like biomass energy such as wood.
