FOSSIL FUELS
NATURAL GAS
found in deposits of petroleum
transported by PIPELINES
made up of
Methane mixed (butane-propane-ethane)
before it can be used
it's cleaned + all gases are removed (NO Methane)
mainly used Heating + Cooking
provides 23% word's energy
quite efficient (making electricity)
is relatively ---
clean-burning
contains only Solphur+Nitrogen
OIL
petrolio
it comes from CRUDE OIL (or Petroleum)
Liquid Fuel
CRUDE OIL recovered by
Drilling Wells
through the rock barrier that traps it
Cleaned from impurities
in an OIL REFINERY
Separated into different products such as
gasoline-diesel fuel-kerosene tar and petrochemicals
provides 40 % world's energy
COAL
carbone
first fossil fuel to be used
recovered from the earth by
MINING (estrazione)
DEEP MINING
provides 27% world's energy
relatively easy to use to
Generate Energy
because only require direct combustioni
Natural Substances
