Resources Notes Renewable vs Nonrenewable A renewable resource
Resources Notes
Renewable vs. Nonrenewable • A renewable resource is a natural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. • A nonrenewable resource is a natural resource that cannot be renewed or replaced.
Fuel • Fuel: a substance that provides energy as a result of a chemical change. • Energy: The ability to do work. – Examples of energy provided by fuel: • • Heat Light Electricity Motion
Energy Transformation • Definition: changing from one form of energy to another • Also called: • energy conversion
Combustion • Fuel contains stored chemical energy which can be released by combustion or burning. • When fuels are burned, the chemical energy that is released can be used to generate other forms of energy, such as heat, light, motion and electricity.
Making Electricity
Fossil Fuels • Definition: Energy-rich compounds that are formed from the remains of organisms. • Fossil fuels are made from hydrocarbons – which are compounds containing hydrogen and carbon • Fossil Fuels = Nonrenewable energy resource • LIMITED SUPPLY! • Examples: – Coal – Oil – Natural Gas
Coal • Definition: Solid form of fuel from plant remains. • Nonrenewable • Mined from the ground • Formation of Coal: – Textbook page 161, figure 2
Oil • Definition: Thick, black liquid fossil fuel. • Also called petroleum • Nonrenewable Refinery: a factory in which oil is heated and separated into fuels and other products. Petrochemicals – compounds made from oil. (used to make: cosmetics, plastics, paints, medicines, etc. )
Natural Gas • Definition: mixture of methane and other gases. • Comes from the same organisms as oil. • Less dense than oil • Produced large amount of energy – but releases less pollutants than oil or coal • HIGHLY FLAMMABLE!
