fossil fuels (history and usage) Flashcards
name the 3 main fossil fuels in use
Coal, oil and natural gas
what percentage of global energy demand to these fuels meet
87%
in what years are these fossil fuels estimated to run out
coal ____
oil_____
natural gas ____
coal: 250
oil: 50
natural gas: 70
before fossil fuels, name the sources of power and fuel
slaves
human power
horse power
wood burners
in what century was the industrial revolution
the 18th century
list the 4 uses of fossil fuels
plastics, pharmaceutics, transport and fibres
what reaction are these fuels used for
combustion (generation of heat)
what other process is oil used for
fractional distillation
approximately how long do fossil fuel take to form
2 hundred millions years
name the four soil materials that pressurised the fossils
dirt, rock, sand and silt
since the industrial revolution, is the main driver for electrical power.
growing human population (power, heating and health)
what other uses does coal have
steel production, liquid fuel (refrigerant) and cement.
approximately how many barrel of oil are used at a daily average
19.5 million
describe how fossil/fossil fuels are formed
million of years ago, there were numerous primordial swamps and oceans filled with small lifeforms. over many years and due to unsustainable conditions (smog, ash and heat) many of these plants and animals within the swamps and oceans dies and became buried/sank. over time these materials became buried under sand,silt,dirt and rocks. these materials were under severe pressure and heat for million of years and due to lack of oxygen, they could not decompose naturally and so instead formed what we know today as fossil fuels.
what are the advantages of using natural gas as a combustion alternative, compared to using oil or coal.
0% sulphur dioxide emissions
less nitrogen oxide and no particulate realises.
name 3 substances created through the fractional distillation of crude oil
gasoline (petrol for cars), kerosene (aircraft fuel)and diesel (fuel for acts, lorries and buses)
another term for man-made
anthropometric
what can be used as a substitute for the production of ethanol (a bi-product of oil)
sugar cane
over reliance on fossil fuels can lead to issues in human needs. what conflict occurred within the past few years due to natural gas reliance
Russia doubled Ukraine gas prices, causing riots and disputes between the nations.
what are the two main drivers for an increased electrical need
electric car and electric heating
china has be estimated to double the US energy demand by what year.
2040

____in 2020
____in 2040
meaning at ___% increase over 30 years
global Co2 emissions are set to be:
36.4 million metric tons in 2020
45.5 million metric tons in 2040
meaning at 46% increase over 30 years
