Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and will vanish shortly. Non-renewable types of energy sources are not environmental friendly and can have serious effects on our health & environment. They are called non-renewable because they can not be re-generated within a short span of time. Non-renewable types of energy sources exist in the form of fossil fuels, natural gas, oil and coal etc.
Non-Renewable Types of Energy Sources
Coal:
Coal is a combustible black or brownish-black sedimentary rock formed from fossilized plants. It consists of amorphous carbon with various organic and some inorganic compounds and is normally occurring in rock strata in layers or veins called coal beds.
Chemical energy is stored in coal. Coal is a Hydrocarbon. When coal is burnt its chemical energy comes out in the form of light and heat energy which result in formation of vapors of Carbon Dioxide(CO2) and water(H2O). After this burning (combustion) ashes are left which different chemical bonds.
Gas:
Natural gas is a combustible mixture of hydrocarbon gases that occurs with petroleum deposits consisting primarily of methane. It is found with other fossil fuels and in coal beds and is created by the decay of methanogenic organisms in marshes, bogs, and landfills. Lower temperatures are likely to produce more petroleum, and higher temperatures are likely to produce more natural gas.
Oil:
Petroleum, also known as crude oil, is a naturally occurring toxic combustible liquid primarily made up of hydrocarbons. Petroleum is the result of partial decay of living organisms occurring in the rock strata of certain geological formations.
Nuclear fuels:
Nuclear power is produced by controlled nuclear fission (splitting atoms). In most cases nuclear power plants use nuclear fission reactions to heat water, using the steam to produce electricity. Uranium, specifically, uranium -235, is one of the few elements easily fissioned.
Wood:
Wood and wood products used as fuel, including round wood (cord wood), limb wood, wood chips, bark, sawdust, forest residues, charcoal, pulp waste, and spent pulping liquor.
