1.5 million years ago a spark lit the
first human-made fire and ignited a
great revolution for our species a
revolution of energy our ancestors first
use energy by burning biomass like wood
to create fire fire was eventually
controlled and used to cook food cooking
breaks down food quicker than a primates
our justice system and allows for a
greater intake of calories in a shorter
amount of time
this extra nourishment enabled our
energy intensive brains to grow larger
extra time previously used for foraging
and eating could now be spent on more
cerebral tasks like thinking socializing
and creating in 6000 BCE early humans
created a thermally insulated chamber
used for drying and hardening clay known
as a kiln which became a common
technology by burning biomass and
generating temperatures in excess of 900
degrees Celsius humans can now create
pottery tiles and bricks as technology
advanced kilns became hot enough to melt
metal humans eventually pioneered in
metallurgical studies the science of
metals in 3200 BCE civilizations and
places like the Middle East Asia and
Europe discovered that the smelting of
copper with tin created bronze a hard
durable alloy this technological leap
gave life to the bronze age an age which
fostered trade agriculture and the first
intermingling of cultures while early
kilns were hot enough to melt copper and
tin advancements were needed before they
could melt iron a stronger more abundant
metal
it was also discovered that infusing
iron with carbon resulted in a high
tensile alloy known as steel in 1200 BCE
steel transformed civilization and move
2mins into the Iron Age the Iron Age was
a period of lighter sharper weapons
armored Calvary and more resilient tools
today still remains one of the
foundational building blocks of our
modern society in 300 BCE humans
harnessed the energy of flowing water
water wheels were used for drawing water
from rivers to fill aqueducts irrigate
farmland and to mill flour Oh energy and
wind was later captured using windmills
starting in 900 AD in Persia and
independently in Europe wind energy was
primarily used in greeneries for powder
and grains into flour used for cooking
and baking in the 1800's mankind saw a
second energy revolution the revolution
is transformational as first harnessing
fire the use of fossil fuels the first
major fossil fuel pole saw demand soared
during the Industrial Revolution as a
flurry of new mechanical and electrical
technologies emerged from steam engines
to electric turbines the world was
transformed with industrial machinery
and communication for the first time in
history humans could travel at state's
greater than a horse on land and faster
than the wind
about the same time natural gas was
discovered and used in Britain and the
United States for additional lighting in
the evenings this extended the hours of
human productivity deep into the night
as a result of the technological and
energetic changes from the Industrial
Revolution household incomes rose across
the world and populations boom the coal
powered steam engine was eventually
overtaken by the oil powered internal
combustion engine during World War one
Sir Winston Churchill and the British
Navy opted to replacement steam-powered
battleships with oil powered ones which
were faster and more maneuverable this
technology gave Britain a significant
military advantage over the Germans who
are using the now outdated steam power
ships this switch from coal to oil has
been argued to thin the deciding factor
in World War one it clearly cemented oil
as the most important commodity on earth
oil was later harnessed for things like
plastics asphalt commercial aviation and
space travel while the First World War
gave rise to oil a second gave rise to
nuclear after Albert Einstein's famous
equation e equals mc-squared
demonstrated the colossal quantities of
energy inside an atom the scientists and
engineers of the Manhattan Project
unleashed the power of the atom with two
nuclear bombs dropped on Japan
that atomic energy was later harnessed
to boil water into steam which could
spin turbines to generate electricity
the future is unknowable creating and
focusing energy and the discovery of new
energy sources has been the genesis for
technological advancement Thomas Edison
didn't create the lightbulb from an
incremental improvement of the candle
but neither has electricity replaced the
need for fire our ancestors who first
learned to harness fire could not have
imagined their descendants using fire to
travel to the Stars as we weigh the
benefits of a fossil fuel powered
society with its long-term drawbacks
like scarcity and climate change the
future remains uncertain with increasing
global populations and rising individual
energy needs the only certainty is we
will use more energy tomorrow than we do
today
