Coal:
Bringing hot water from coal mines
to houses was too difficult. James Watt basically solved
this problem by inventing the steam engine. His invention
totally changed the whole life of industry and
transportation.
1885-1950 Although producing heat from coal in
compare to wood was cheap and twice efficient, but
cleaning the houses that heated by coal was very
difficult.
1993 and on the demand for oil in the U.S.A has passed
the production due to decline in oil production.
Nuclear:
1906 Albert Einstein’s theory of relativity opened a new
chapter in the field of physics. The Theory speaks about
mass, Light, energy, electricity and magnetism. The most
important development of the 20th century was
the invention of formula by Einstein, called E=MC2
It says that energy is equal to mass multiply by square
of the light speed. This invention opened new era in the
fields of medicine, astrophysics, and electricity.
1942 Nuclear Energy was introduced in this year.
1957
In
this year the first nuclear energy plant started its
production.
1995 Nuclear power plants produce 20 Percent of
electricity.
Transportation:
1781 Passenger travel was only possible by horse-drown
coaches.
1800 Horse coaches mainly moved goods and
passengers. In this year there were no trains, no big
ships, as we know to day.
1980’s Coal became the super star
to the steel industry.
1982 Although coal was not used
for heating in the houses but became the main source for
generation of electricity. In general heating the coal
generated 50 percent of energy, but only 10-15 percent of
energy generated from natural gas, nuclear power or from
dams.
