متن انگلیسی درباره Fossil Fuels سوختهای فسیلی

All the machines of modern life require energy to make them run. About 90 percent of that energy comes from burning fossil fuels. Fossil fuels include petroleum (oil), coal, and natural gas. These materials are called fossil fuels because, like fossils, they are the remains of organisms that lived long ago. Organisms are plants, animals, and other living things.
Fossil fuels formed in the Earth hundreds of millions of years ago. Dead organisms sank into mud and rock. Over time many layers of rock built up. The remains of the organisms slowly changed in form to become different kinds of fossil fuels. Coal came from plants. Petroleum and natural gas came mainly from microscopic organisms such as algae.
Fossil fuels and their products have many uses. Power plants use fossil fuels to produce electricity. People heat their homes and other buildings by burning fossil fuels. Gasoline, a product made from petroleum, fuels cars and other kinds of motorized equipment.
Many countries produce fossil fuels. The greatest producer of petroleum is Saudi Arabia. Russia has the largest reserves of natural gas. Major coal-producing countries include the United States and China. The United States uses more fossil fuels than any other country.
