Oil+-+Lara

Oil is a non-renewable energy source because it takes millions of years to create. It is formed from the remains of animals and plants that lived millions of years ago in a marine environment. These animals and plants then eventually died, sunk to the ocean floor where they were later on compressed by sand and silt. Heat and pressure turned these remains into what we call crude oil today. The world “petroleum” means “rock oil” or “oil from the earth”. Today we drill through layers of rock, sand and silt to reach the oil.  Oil is used to propel cars, trucks, boats, to heat homes, and drive industry and to provide raw material for petrochemicals. Oil can be made into power in lots of ways. It is a fuel or source of energy, which is usually combusted. When it is combusted, chemical energy is transformed into kinetic energy, and can be used to do things such as move pistons in a car’s engine. Oil combustion is exothermic, so it also releases thermal energy (heat). This heat can be used to boil water – to spin turbines – to make electrical energy. **Chemical** **à** **Heat** **à** **Kinetic** **à** **Electrical.**

Other products made from petroleum include: - Ink - Crayons - Dishwashing liquids - Deodorant - Eyeglasses - CDs and DVDs - Tires - Ammonia - Heart valves.

OPEC (Organization of Petroleum exporting countries) believes that oil demand will continue to grow strongly and oil will remain the world's single most important source of energy for the foreseeable future. Oil is expected to account for 32% of the world’s energy supply by 2030 from about 36% in 2006. The top five crude oil producing countries are: - Saudi Arabia - Russia - United State - Iran - China
