Drilling deep for knowledge about fossil fuels
the energy from sunlight stored in the tissues of the buried organisms as a result of photosynthesis
a natural substance like oil or coal, formed from the buried remains of organisms
usage has steadily increased since the Industrial Revolution
At the start of the 21st century, fossil fuels made up nearly 90 percent of the world’s energy supplies
Coal, petroleum and natural gas are the most commonly known fossil fuels.
the most widely used of the solid fossil fuels
creat during the Carboniferous Period, which was about 359 to 299 million years ago
Hard coals are considered the best energy sources among the coals because they burn the hottest and do not release as many pollutants into the air
Oil And Natural Gas
Petroleum, or oil, is the most common liquid fossil fuel and natural gas is the most gaseous fossil fuel
As these organisms died and sank to the muddy bottom, their buried remains changed into a substance called kerogen.
Natural gas is used for heating and cooking in the home and for industrial heating. It is also used to generate electricity.
Where Fossil Fuels Are Found
United States, Russia, and China have the largest coal deposit
Australia, India and South Africa have large amounts.
The Middle East contains more oil than the rest of the world combined.
Other Fossil Fuels
Peat and coke are solid fossil fuels that are commonly used today
Peat is used as a heating fuel in areas where other fuels are not available
Coke is a residue that remains after gases and tar are extracted from some types of coal
Extracting useful substances from them is difficult and costly -> these resources were not good fuel options.
Limited Supply, Pollution Problems
. Burning petroleum and coal releases harmful gases into the air. These gases pollute the air and react with moisture in the atmosphere to create acid rain
Burning fossil fuels also releases carbon dioxide into the atmosphere -> contributes to climate change
These problems have led scientists and engineers to develop new ways to generate power without using fossil fuels.
