throughout human history access to
energy resources has often meant the
difference between illness and health
poverty and wealth and illiteracy and
education so it's not surprising that
today the world's energy use is growing
even faster than its population Global
energy consumption has doubled since the
early
1970s and experts predict it will expand
another 50% by
2035 unfortunately this Rising demand
poses a couple of major problems the
first is that most of the energy sources
we rely on today won't last forever coal
oil and natural gas supply about 80% of
the energy we currently use and while
these fuels continue to form through
natural processes we're using them much
faster than they're being created in the
us alone we burn more than 100,000 tons
of coal and nearly 800,000 barrels of
oil every
hour so unless we develop large scale
Alternatives when these fuel sources run
out our power supply will run out too if
that weren't enough burning fossil fuels
releases a lot of carbon into the
atmosphere mostly in the form of carbon
dioxide and all this CO2 is affecting
earth's climate carbon dioxide and other
greenhouse gases build up in in the
atmosphere as they do they act like
insulating blankets allowing sunlight to
pass through to Earth's surface while
slowing the release of heat back into
space the more CO2 in our atmosphere the
warmer our planet becomes and this will
affect everything from sea levels and
ocean currents to weather patterns and
Seasons leading to more natural
disasters and potential food shortages
in our future these problems of
skyrocketing energy demand dwindling
resources and increasing environmental
consequences are very real and
scientists agree it's not a question of
if but when these problems will catch up
with us so the race is on to find new
energy sources and Innovative
Technologies it's our best hope for a
sustainable future
