the concept of clean energy has become
[3]
the trend recently with climate change
[5]
and other environmental issues the
[8]
global transition towards clean energy
[11]
is considered as the most essential
[13]
thing what is this clean energy all
[16]
clean energy and renewable energy the
[18]
same
[20]
what is the difference between renewable
[22]
energy and non-renewable energy to get
[24]
the answer for all these questions

hi i'm danila
[30]
this video is all about energy if you
[33]
want to know whether nuclear power
[34]
plants produces clean energy watch till
[37]
the end of this video for hundreds of
[40]
millions of years plants and animals
[42]
have lived and died their remains have
[44]
gotten buried deep beneath earth's
[46]
surface
[47]
the heat and pressure turn them to
[50]
fossil fuels like coal oil and natural
[52]
gas the fossil fuels we have used over
[55]
the past 200 years were formed over the
[57]
past 500 million years it takes millions
[61]
of years to form and we are removing
[63]
them much faster than that it is like we
[66]
are emptying a bathtub with huge shrine
[68]
while refilling it with a tiny slow drip
[71]
even with the drip the tub will still
[74]
empty completely in the same way if we
[77]
keep burning the fossil fuels at a
[79]
current rate it is estimated that all
[82]
our fossil fuels will be depleted in
[84]
near future in other words once these
[87]
resources are used up they cannot be
[89]
replaced this kind of resources is
[92]
called non-renewable resources
[94]
unfortunately we are depending on
[96]
non-renewable resources as a primary
[98]
source of energy we are burning fossil
[100]
fuels to generate electricity power
[102]
transportation and run industries now
[105]
comes the question of sustainability
[107]
what happens when we run out of fossil
[110]
fuels what will be like to live a life
[112]
without electricity and transportation
[115]
and this is not the only problem we have
[117]
to face with non-renewable resources
[120]
another major problem with this is
[122]
burning fossil fuels releases greenhouse
[124]
gases into our atmosphere which is the
[127]
major cause for climate change now we
[130]
need a solution we need resources that
[132]
can fulfill our current energy needs
[134]
without affecting future generations
[137]
that's when renewable energy comes into
[139]
picture
[140]
what is renewable energy
[142]
renewable energy is the energy we derive
[145]
from many earth's naturally available
[147]
resources including wind water and sun
[150]
these resources will be with us today
[153]
tomorrow and years to come now let's see
[156]
few renewable energies we use now let's
[159]
start with solar energy solar panels
[162]
convert the light energy from the
[163]
sunlight into electrical energy another
[166]
important energy is wind energy the wind
[169]
turbines convert this wind energy into
[171]
electrical energy the earth's gravity
[174]
makes the water to flow downwards the
[176]
hydropower plants convert this flowing
[178]
water into electrical energy now let's
[181]
talk about the energy from moon as the
[184]
moon's gravitational pull generates
[186]
tidal force the tidal stream generators
[189]
draws energy from water currents and
[191]
converts it into electrical energy we
[194]
all know that in thermal power plants we
[196]
burn coal and natural gas to produce
[198]
steam which runs the turbine as i said
[201]
earlier this coal and natural gas are
[204]
non-renewable resources if we can
[206]
produce steam from renewable resources
[208]
then we will get renewable electricity
[211]
we have three different renewable power
[213]
plants that uses the same thermal power
[215]
plant technology first one uses the
[218]
earth's internal heat to produce steam
[220]
this is called geothermal energy this
[223]
thermal energy is contained in the rock
[225]
and fluids beneath earth's crust second
[228]
one produces heat from burning wood as
[231]
biomass energy is derived from organic
[233]
matter such as wood or crop waste
[236]
third one uses the temperature
[238]
difference between the ocean surface
[240]
water and deep ocean water to produce
[242]
steam ocean thermal energy conversion or
[245]
votec produces renewable electricity if
[248]
you want to know more about this otech i
[251]
have got a video over here where i have
[253]
explained this concept very clearly
[256]
please do check it out
[257]
electricity from renewable resources
[259]
generally do not contribute much to
[262]
climate change or air pollution so do
[264]
you think renewable energy is clean
[266]
energy if not what exactly is clean
[270]
energy clean energy works by producing
[272]
power without having negative
[274]
environmental issues although the
[276]
impacts are small some renewable energy
[279]
technologies can have an impact on the
[281]
environment
[282]
for example large hydroelectric
[284]
resources can have environmental issues
[287]
like deforestation clean energy also
[290]
means zero emission for example burning
[293]
wood from sustainably managed forest can
[296]
be renewable but it is not clean since
[298]
this releases carbon dioxide into the
[300]
atmosphere so overall solar energy and
[304]
wind energy are seen as being truly
[307]
clean and renewable the clean power
[309]
source for engine is hydrogen fuel cells
[312]
here the electric motor is powered by
[314]
the electricity generated from the
[316]
hydrogen when hydrogen gas is converted
[319]
into electricity just water and heat are
[321]
released that is it produces
[324]
zero harmful vehicle emissions now what
[327]
about nuclear energy is it a renewable
[330]
or non-renewable energy nuclear power
[333]
plants uses uranium although uranium is
[335]
found in rocks all over the world
[338]
nuclear power plants usually uses a very
[341]
rare type of uranium u235 therefore it
[344]
is a non-renewable energy the best thing
[347]
about the nuclear energy is that they
[349]
produce clean energy that is they emit
[352]
zero emissions
[354]
but the radioactive waste they produce
[356]
can be extremely toxic so while building
[359]
the nuclear power plant safety should be
[361]
given the first priority if you find
