my grandmother was a housekeeper in
the highs of saint paul for a rich
family descendants of the family of
basins his grandfather was a slave
the shore by boat as animals
positive bastien his daughter my mother was
hairdresser and I am electro
chemist
so I am a student researcher I
works at the university of the meeting
in energy physics
since very young she kept telling me
thing my child my child is not letting
sun except umbria in the morning at night
my child spas sun except zombré
literally in French that means
do not let the sun heat up and at
navel so to remove her from big
things work you have to get up everything
you have to have toughness
self-denial for great success
things this thought guided me during
my studies and in my current job
second thing the sun is thanks to
this Creole saying that I understood
paradoxically that the sun was a
immense energy
let’s talk about energy you know that the island
Of the reunion
we do not have fossil energy this
that I mean by fossil energies what
are all those energies that are not
renewable fuel oil coal for
the example but we have the sun
solar energy can be captured through
photovoltaic panels
we have wind energy the wind
we have the energy of the seas and we
also have energies that are
untapped such as geothermal energy at
the challenge
a simple question why in
2007
soon 2008 solar energy is not
our primary resources why 67 %
electrical energy that is produced
on the island of the meeting comes from
fossil energy to there are answers
so what is this a
technical scientific problem
political economy
you know I’m a scientist and I
will talk about science
the answer is in the question this is
a multiple problem with many
answers we can say good let’s develop
solar energy so let’s take some
photovoltaic panels and put in
on the roof on our schools
even on our heads this is what we are
is currently selling the expansion of
solar energy panels
PV
but that’s only a small part of the
reply
Why
solar is by definition an energy
fluctuating
indeed when you have one of the sun
nice sunny day you have a
electric production
the photovoltaic panel you have a
cloud this fall production
you have the night that comes there is no
more production so this energy
is by definition fluctuating
it is intermittent and we can not
consider as a constant energy
in the same way as the fossil so the
real problem behind
renewable energies
it is the storage of these energies then
what to do so
let’s go back to the time lontan invest
in the oil alan finger candle
it’s going to bef all the love I have
own Creole Reunionese culture I
do not think it can be
possible at the moment consumption
and tablets computer consoles of
games have self tune and it’s not
possible
to develop things that’s
my job is the work of
my colleagues at the university meeting
including storage
let’s talk about this storage two scenarios
possible
take a Reunionese family
single parents two children and
photovoltaic panels installed on
the roof of the house
you have beautiful days
sunshine the panel
photovoltaic will produce you from
electricity
imagine that this production is
greater than the demand
we stop the surplus of
cyclone scenario sullen day the
electricity production is less than
the demand
we use the heavens more than we have stored
to produce electricity
it’s very simple we call it
decentralized energy
I think that’s the future then
storage you tell me but it exists
why it’s not answered on the island of
the meeting
storage we know we all have
batteries in our cars
lead batteries
we have in our phones and
lithium battery of our computers
but the step in the paradox is there one
can not store energy
renewable using a storage
which is not renewable
so we need to develop
renewable storage systems this is
there that hydrogen intervenes in paris to
hydrogen
let’s talk about hydrogen take a
molecule from where they water molecules is
composed of one oxygen atom and two
hydrogen atoms are held by
lions if I put an electric source
electrons with
on ecology you get to
dissociate these anti social molecules these
molecules I get to get from
the hydrogen this process it exists since
long time
this is called the electrolysed water
so from water zoo algae
their cock for example you
did not store electrical energy
without going through topics such as
lead such as incidental materials
which are renewable
it’s beautiful the reverse process
also exist
take hydrogen you just
create you put with oxygen
you gather and you have a
electrical production the process exists
it’s called fuel cells and
which is beautiful in these
technologies that I defend I believe
highly secure the only reagent that h2o
so there we are totally renewable
he has several locks still to lift the
first lock that’s the price it costs
expensive
saving the second lock the
durability
the systems have to be more
more sustainable
the third verse where the sua t1 that sits
as we do to answer 7 this
problematic of this yacht and I you
say you have at home with goals
butane and propane bottles
highly flammable
so in fact following pedagogy for not
tell this problem the yacht is
so sect at home this technology
it exists and I hope we
will allow tomorrow to the east of the meeting
the mauritius island seychelles
all these islands of the Indian Ocean that
have a strong solar potential to have a
coefficient of energy dependency
close to zero bye bye the oil
we consume what we produce
my dream
I imagine this meeting tomorrow we
consume what is produced
I imagine this meeting tomorrow which
no longer needs to call someone to
15000 kilometers to bring some
tons and tons of fuel
I imagine a meeting tomorrow where each
family each neighborhood has its own
electric production
I think it’s possible the
energy transition is possible I
quote a sociologist florence rey us
the says that energy is not a
simple variable that feed a
system
it’s a choice it’s a social choice
energy is a societal choice
no society it’s you it’s us and
our children
so please make your choice
I will end up
little anecdote you know in the
80s at the island of the meeting
we were renewable without fish
have worked totally on energy
hydroelectric on the island of the meeting
before the 80’s we were 300 miles
we did not have that way of life that we
currently have
but what’s so funny about it when
we listen to the global discourse that we
of course you have to go to
new technologies
directing the great consciences of
scientists
the future will be renewable what is
paradoxical is that we our past and
is renewable and as
reunion as a island law as
that people without resources
fossil
the future our future will be our past
will be the return to our old values
at the reunion its Creole values of
reasoned consumption of consumption
decentralized me I find that
beautiful to finish it was I like
maloya badly thanks to the music
traditional island meeting
I love this style I also like the
science as you could understand it
and with my friends we invent to invent
a maloya renewable maloya
renewable energy
it’s like that in the sunshine clerity
baballe is dirty clery when lives
happens to t1 to rodez way for
turn ali thank you
