Fossil fuels

Facts: 1. Fossil fuels ultimately get their energy from the sun. The plants 2. 85.6% of all energy consumed in the U.S. comes from fossil fuels 3. Greenhouse gases act like a blanket around Earth, capturing energy in the atmosphere and causing it to warm.

Fossil fuels are the remnant of plants and animals. They contribute us with a source of nonrenewable energy. Fossil fuels can either come in the structure of an oil, coal, or natural gas. They are the result of the decomposition of dead plant and animal matter buried deep in the Earth's crust. These fossil fuels are then pumped from underground and used in a variety of ways.

Facts [cont.]: 4. Fossil energy sources, are non-renewable resources that formed when antient plants and animals died and were little by little buried by layers of rock. Over millions of years, different types of fossil fuels formed 5. Millions of years ago, Fossil fuels are formed by the anaerobic decomposition of remains of organisms including phytoplankton and zooplankton that settled to the sea (or lake) bottom in large quantities under anoxic conditions

Facts [cont.] 6. Coal is a hard, black colored rock-like substance formed when dead plants were subjected to extreme heat and pressure for millions of years. It is made up of carbon, hydrogen oxygen, nitrogen and varying amounts of sulfur. 7. Natural gas was formed from the remains of tiny sea animals and plants that died millions of years ago. The gas then became trapped in layers of rock like water in a wet sponge.

Facts [cont.] 8. Oil was formed from the remains of tiny sea animals and plants that died millions of years ago. The organic material was then broken down into hydrogen and carbon atoms and a sponge-like rock was formed, full of oil. 9. When fossil fuels are burned, they release unhealthy toxins into the air we breathe.

Facts [cont.] 10. At current usage, the coal supply will last 1500 years. However at a 5% growth rate the coal supply will last only 86 years.
