COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considerednonrenewable because they can not be replenished in a short period of time. Theseare called fossil fuels.
COAL Coal is the most abundant fossil fuel in the world. During the formation of coal, carbonaceous matter was first compressed into a spongy material called "peat,“. When the coal is burned, the pollutant sulfur dioxide is released into the atmosphere.
OIL AND GAS Oil forms underground in rock such as shale, which is rich in organic materials. oil also provides base material for plastics, provides asphalt for roads and is a source of industrial chemicals. Natural gas is a mixture of gases, CH4,C2H5,C3H8,C4H10. Natural gas is highly flammable and is odorless.
NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!
Nuclear Reaction Ba n U + n → 139Ba + 94Kr + 3n235 U 235 n n Characteristics: Kr • Bombarded by neutron Ba n Ba n • Chain reaction: n U 235 n U 235 n n n 1 neutron in, This neutron starts the chain reaction Kr Kr 3 neutrons out. Ba n U n 235 But not every neutron can hit n Kr an 235 U nucleus.
COST AND AVAILABILITY : For example, it is difficult to find a car or truck that runs off of rechargeable battery power, solar power, or electricity
When theyre gone, theyregone.You cant replace natural gas,oil, or coal. Also, mining for these sources at such an intenserate can have devastatingenvironmental effects.
